Una célula de medición inductiva consiste en dos bobinas, una transmisora y otrareceptora. Ambas bobinas se montan una junto a la otra . La zona de las bobinas sesumerge en el líquido y este pasa a través de los agujeros de las bobinas toroidales. Acontinuación se aplica una tensión alterna sinusoidal a la bobina transmisora. Estoproduce una corriente en el fluido proporcional a su conductividad. A su vez, estacorriente induce una tensión en la bobina receptora. La conductividad se determinamidiendo esta segunda tensión y conociendo la constante de la célula. El sistemaintegra también un sensor de temperatura que permite aplicar correcciones detemperatura.

SENSORES DE CONDUCTIVIDADTecnología

La conductividad eléctrica, se define como la capacidad que tienen las salesinorgánicas en solución ( electrolitos ) para conducir la corriente electrica.

El agua pura, practicamente no conduce la corriente, sin embargo el agua con salesdisueltas conduce la corriente eléctrica. Los iones cargados positiva y negativamenteson los que conducen la corriente, y la cantidad conducida dependerá del número deiones presentes y de su movilidad.

En la mayoría de las soluciones acuosoas, cuanto mayor sea la cantidad de salesdisueltas, mayor será la conductividad, este efecto continúa hasta que la solución estátan llena de iones que se restringe la libertad de movimiento y la conductividad puededisminuir en lugar de aumentar, dándose casos de dos diferentes concentraciones conla misma conductividad.

Temperatura de la muestra 25 ° C Conductividad, µS/cm

Agua ultrapura 0.05

Agua de alimentación a calderas 1 a 5

Agua potable 50 a 100

Agua de mar 53.000

5 % NaOH 223.000

50 % NaOH 150.000

10 % HCl 700.000

32 % de HCl 700.000

31 % HNO3 865.000

Algunas sustancias se ionizan en forma más completa que otras y porconducen mejor la corriente. Cada ácido, base o sal tienen su curva característica deconcentración contra conductividad.

los ácidos, bases y sales inorgánicas: HCl, NaOH, NaCl,Na CO ....etc.

: Las moléculas de sustancias orgánicas que por la naturalezade sus enlaces son no iónicas: como la sacarosa, el benceno, los hidrocarburos, loscarbohidratos.... etc, estas sustancias, no se ionizan en el agua y por lo tanto noconducen la corriente eléctrica.

Un aumento en la temperarura, disminuye la viscosidad del agua y permite que losiones se muevan más rapidamente, conduciendo más electricidad. Este efecto de latemperatura es diferente para cada ion, pero tipicamente para soluciones acuosasdiluidas, la conductividad varía de 1 a 4 % por cada ° C.Conociendo estos factores, la medición de la conductividad nos permite tener unaidea muy aproximada de la cantidad de sales disueltas.

esta razón

Son buenos conductores :

Son malos conductores

La conductividad eléctrica es lo contrario de la resistencia en ohms, medida entre las carasopuestas de un cubo de 1.0 cm de una solución acuosa a una temperatura especificada. Estasolución se comporta como un conductor eléctrico donde se pueden aplicar las leyes físicas de laresistencia eléctrica.Las unidades de la conductividad eléctrica son el Siemens/cm ( las unidades antiguas, erán losmhos/cm que son numéricamente equivalentes al S/cm ).En la práctica no se mide la conductividad entre electrodos de 1 cm sino con electrodos dediferente tamaño, rectangulares o cilíndricos, por lo que al hacer la medición, en lugar de laconductividad, se mide la conductancia, la cual al ser multiplicada por una constante ( k ) de cadacelda en particular, se transforma en la conductividad en S/cm.

Conductividad = Conductancia de la muestra * kk = d/A

k: Constante de la celdad: distancia de la separación de los electrodosA: Area de los electrodosAsí, un electrodo de 1 cm de separación y con una

area de 1 cm , tendrá una k = 1

La medición eléctrica se efectúa mediante un puente de Wheastone para medir resistencias.Las resistencias R1 y R2 son fijas y su valor va de acuerdo al intervalo de conductividad que sepretende medir. La resistencia Rx es la que proporciona la solución a la cual se le va a medir laconductividad. La resistencia R3 se varía en forma continua hasta poner en equilibrio el puente, detal forma que no pase corriente hacia el medidor.

INTERFERENCIAS EN LA MEDIDASustancias no disueltas o materiales que precipiten lentamente en la muestra, puedencausar ensuciamiento en la superficie de los electrodos y causar lecturas erroneas.El ensuciamiento por sustancias orgánicas, bioensuciamientos y corrosión de loselectrodos, causan lecturas inestables o erroneas.El factor de correlación para obtener los valores cuantitativos de los sólidos totalesdisueltos solo es válido cuando la muestra tiene un pH entre 5 y 8, a valores mayoreso menores de pH, los resultados no serán confiables.


CONDUCTIVIDAD INDUCTIVA

Una célula de medición inductiva consiste en dosbobinas, una transmisora y otra receptora. Ambasbobinas están integradas en un alojamientohueco. El alojamiento se sumerge en el fluido, queinunda su interior. A continuación se aplica unatensión alterna sinusoidal a la bobina transmisora.Esto produce una corriente en el fluidoproporcional a su conductividad. A su vez, estacorriente induce una tensión en la bobinareceptora. La conductividad se determinamidiendo esta segunda tensión y conociendo laconstante de la célula. El sistema integra tambiénun sensor de temperatura que permite aplicarcorrecciones de temperatura.

080102.1pH and O.R.P. microtransmitter

The microtransmitter is a differential preamplifier enclosed in a water-tighthousing and makes the characteristics of the measuring electrodes signalcompatible to those of a normal connection cable.

With this technically advanced solution it is possible to make connectionsat considerably long distances between the measuring probe and thecontrol panel without the use of a shielded cable maintaining a high signalresponse speed and the complete absence of interferences, thereforegreater precision.

The connection between the microtransmitter and the panel regulator ismade using a 4-pin waterproof connector type SZ 9490 and a normal4-wire cable.

The accessory type SZ 9491 consisting of SZ 9490 + 10 m marked cable isavailable.

The microtransmitter is protected against eventual connection inversions.It is mounted in the usual way on ST type probes.

For unfixed mounting, the SZ 911 accessory must be used.Recommended cable: 4 x 0.5 mm or 4 x 0.75 mm non shielded.

Gas sensing analyzersResidual Sulfite, D. Sulfide, Total Residual Chlorine

This Monitor series takes a unique approach to the measurement of ionconcentration. In operation a small amount of sample is pumped into thesystem and mixed with a suitable reagent.The mixed sample flows into a special chamber where the ion is convertedin a gas stripped from the sample.A sensor located in the gas stream measures the gas concentration anddisplays the results in terms of equivalent ion concentration.

Monitors consist of two separate components:

- a chemistry module where the sample is conditioned properly to make themeasurement

- an electronic readout module containing the measuring display, analogoutput, and alarm contacts.This module is the S 7685 for Sulfite/Sulfide, and the CL 7685.010 for theTotal Chlorine.

A 25 foot sensor cable is supplied to connect the two modules together, andthe separation can be increased to 100 feet by the use of a junction box andadditional signal cable.

A sample inlet overflow block is provided on the left side of the chemistrymodule.Systems are extremely easy to operate and maintain, with the reagentusage limited to one liter every 10 days at standard flow rate.Sample and reagent are pumped using long life peristaltic pump tubingthat requires replacement approximately every 6 months.The sensor requires no maintenance other than an occasional visualinspection to insure that no deposits have collected due to airborneparticulates.

Dissolved OxygenAutoclean system

• Applications:- water treatment- activated sludge- de-nitrification- fish pond

The on-line monitoring system is designed for the continuousmeasurement of oxygen gas in solution.

The full scale operating range of the system may be selected by the userfor 0-20.00 PPM or 0-40.00 PPM, and the sensing system will operateon water streams with temperature from 0 to 50 °C.

The measured dissolved oxygen concentration is displayed on a backlitliquid crystal display on the front of the instrument. The D.O. monitor iswell suited for wastewater treatment aeration tanks, effluent monitoring,or stream monitoring.

The basic sensing element used in the D.O. monitor is a galvanicmembraned sensor assembly that automatically delivers high pressureair to the tip of the sensor to effectively blast accumulated growth fromthe membrane.

The system includes two main components and fittings:

• OD 8112 D.Oxygen assembling with cleaner

• OD 8182 D.Oxygen sensor with cleaner nozzle

• Installation accessories

• Spares

For special applications, the D.O monitor can be supplied without thecleaner, and the customer will provide the pressure air to the sensor.

Submersible sensors are designed for direct immersion in an aeration tankor flowing stream.

A 15 m cable is potted into the top section of the sensor assembly, andconnects directly to the D.O. monitor,.A separate tubing connection located at the top of the sensor assembly isprovided for connection of a 15 m length of plastic tubing between thesensor and the monitor.

The D.O. sensor assembling is mounted to a 1" pipe using a specialmounting adapter.The 1" pipe is attached to the tank handrail with a bracket assembly thatholds the sensor at a slight angle in the tank.

Once installed and placed into operation, the Autoclean D.O. sensor willprovide months of reliable D.O. measurement in almost any application.Sensor should be checked for build-up after the first 3 months to verify thatthe cleaner is keeping the membrane clean.However, sensor maintenance intervals of 6 months or more are likely inmost aeration tanks.

The sensor cleaning frequency is user programmable, and units are shippedwith a default cleaning frequency of once every 24 hours.This frequency has proven sufficient for most aeration applications, but canbe increased if needed for a specific application.A cleaning frequency of more than every 2 hours is not recommended.

System installationThe installation of the auto-clean D.oxygen system is quick and simple.A special mounting adapter connects the sensor to standard 1" conduit orpipe, and another adapter provides secure connection of the pipe to astandard handrail system.

SZ 283Potentiostatic electrode

This sensor is made for the measurement of Free Chlorine, Chlorinedioxide and D.Ozone in water.

The potentiostatic method is an “amperometric” measure with constantpotential, made through 2 metal electrodes and a reference electrodedipped in a cell.

The current running through the cell consumes Chlorine or Ozonecontents, therefore they must be renewed through a constant liquid flow.

In the traditional amperometric measurement it results difficult tomaintain a constant relation between cell current and Chlorine (Ozone)concentration, especially near the zero, because of the ORP and liquidresistance effects. As result frequent zero and sensitivity calibration areneeded.

In the potentiostatic measuring, the electrodes potential is electronicallycontrolled in relation to the liquid, providing a linear relationshipcurrent/concentration and a very stable zero value in oxidative absence.

The sensor is shaped so that it is easy to clean and replace.

It is suggested to place the sensor in a measurement cell SZ 7231or SZ 7233 provided with overflow in order to maintain the sample flowconstant.If placed in different types of cells or in a pipe-line, in order to avoid aninstable measurement, it is necessary for the flow to be constant.

CL 7615Potentiostatic Chlorine controller

This unit, together with the flow cell and the potentiostatic electrode, is thebest and most advanced system for chlorine measurement.Because of the potentiostatic measuring method, it is not necessary torecalibrate the zero, the measuring is very accurate and direct chlorinereadout appears on the display.Also this accurate method prevents the fluctuation of the chlorine levels ason the amperometric and ORP methods.

This potentiostatic system represents the state of the art in the drinkingwater, swimming pool industry and others.
