ENDRESS+HAUSER  CLS13-A1D1A

This conductivity sensor is designed for industrial and power plant applications (e.g. condensate measurement) where low conductivities must be measured under high pressures and temperatures.

The measuring range of the sensors depends on the cell constant k.

• k = 0.01 cm –1 : 0.04 ... 20 μS/cm
• k = 0.1 cm –1 : 0.1 ... 200 μS/cm

Sensors with a Pt 100 temperature sensor are used together with conductivity measuring instruments equipped with automatic temperature compensation:

• Mycom S CLM 153
• Liquisys M CLM 223/253
• MyPro CLM 431

For measurement of specific resistance, MΩ · cm measuring ranges are available in the menues of these transmitters.

With ATEX approval for application in hazardous areas.

• Optimum adaptation to process conditions or mounting place due to different designs
• Mounting in pipes or flow chambers
• Application with temperatures of up to 160 °C / 320 °F and pressures of up to 40 bar / 580 psi
• Simple measuring cable connection due to large connection compartment
• Quality certificate stating the individual cell constant

The conductivity of liquids is measured with a measuring system that has two coaxially arranged electrodes like a capacitor. The electric resistance or its reciprocal value, the conductance G, is measured according to Ohm’s law. The specific conductivity κ is determined using the cell constant k that is dependent on the sensor geometry.
