Industrial Grade Conductivity Sensor KE- CDS 3000 SERIES

The industrial standard KE- CDS 3000 series sensor is used for continuous monitoring of electrical conductivity / TDS of surface water, ground water, pure water, aqueous solutions and industrial effluent water. The durable PTFE enclosure consisting of 316L Stainless Steel twin electrodes which have an excellent chemical compatibility with anticlogging design which provides easy maintenance.

Sensor Features
1- High accuracy with fast response and good repeatability.
2- Works on temperature upto 130°C.
3- High level of process safety due to durable materials and robust design.
4- Widely spaced electrode which do not trap ion exchange resin particles, corrosion particles or bubbles and yield more reliable, maintenance-free operation.
5- Pt1000 RTD, the temperature element used in the KE- CDS 3000 Series sensor is highly accurate and linear throughout the range.

Sensor Installation

1- Do not put Sensor directly into water, the sensor should be installed in Female Thread Socket for Inline Flow through Measurement and Threaded Sensor Housing for Offline Measurement.

2- Before installation, use Teflon Tape ( 3/4" Thread) to ensure no leakage occurs.

3- Connect the Sensor to Controller, let it stable for 3 Mins, then start calibration work.

4- Connect / Insert the Sensor vertically upright in the calibration Solution whenever doing calibration.

5- Sensor to be installed Inline to piping where the pipe line doesn’t get dry whenever process is not operational.

6- Sensor to be installed in pipe lines opposite to flow direction.

× Sensor Maintenance

1- Check if the tinned wires are dry and clean, otherwise use ethanol to clean and blow some air to wipe out dust particles.

2- Stir the test solution with sensor to accelerate sensor response when calibrating than place the sensor in calibration solution.

3- Use 1 point Calibration through any NIST or TCT standard buffer for use with RCB Conductivity Controller KE-CD 1000.

4- The sensor should be cleaned and calibrated periodically, if the junction between sensor electrode and PTFE enclosure is contaminated, use surfactant for cleaning.
