RTM Conductivity Sensor Cell Constant

A. Product Overview

The RTM Conductivity Sensor is an industrial conductivity cell designed to measure the electrical conductivity of liquids in water treatment and process applications. It is available in multiple cell constant options to cover different conductivity ranges, from ultrapure water to high conductivity liquids.

The sensor is available in different model variants including:

RTM-ANL-CTDS-SENS-001K
RTM-ANL-CTDS-SENS-01K
RTM-ANL-CTDS-SENS-1K
RTM-ANL-CTDS-SENS-10K

Cell constant options include:

0.01K for ultrapure water and very low conductivity measurement
0.1K for pure water, RO water and DM water
1K for general water treatment and process water
10K for high conductivity liquids, wastewater, chemical process water and saline applications

The sensor body and contact parts are available in combinations such as S.S. 316, Teflon, Nylon, ABS, PP, PVDF and Titanium. Connection options include 1 inch TC, 3/4 inch thread and 3/4 inch BSP male depending on the selected model. PT-100 temperature output is available for temperature compensation.

B. Working Principle

The RTM Conductivity Sensor works by measuring how easily electric current passes through a liquid. Conductive ions present in the liquid allow current to flow between the sensor electrodes. The higher the ion concentration, the higher the conductivity value.

The sensor is connected to a conductivity controller, transmitter or analyzer. When the sensor is placed in the liquid, the instrument applies a small electrical signal across the electrodes. The response is measured and converted into conductivity units such as µS/cm or mS/cm.

The cell constant defines the measuring range and sensitivity of the conductivity sensor. Lower cell constants such as 0.01K and 0.1K are used for low conductivity liquids like pure water and DM water. Higher cell constants such as 1K and 10K are used for general water, process water, wastewater and high conductivity liquids.

The PT-100 temperature output helps compensate for changes in liquid temperature, improving conductivity measurement accuracy.

C. Why It Is Used
