4 electrodes conductivity measurement with high measurement accuracy

even if the contacts are dirty.
The 4 electrode conductivity measuring cells LM4E are available with cell constants of 0.5, 1.0, 2.0 and 3.0. By putting on different caps it is very easy to choose between cell constant 1, 2 and 3.

The LFTR 40 transmitter is plugged directly onto the 4-electrode conductivity sensor , so that there is no need for any wiring work between the sensor and the transmitter and no cable resistances can be included in the measurement result. From the transmitter it then goes directly to the PLC, whereby the cable length is irrelevant.
A measuring range from 0...120 µS/cm to 0...1200 mS/cm is covered. In between, the finest gradations are possible by changing the measuring cell and by moving jumpers.
The media temperature is measured by NTC and is used for temperature compensation of the conductivity as TK-nat.
The media contacting materials are electrographite , titanium and EPDM. The housing of the measuring cells and the immersion fitting are made of PP.
Thus, a very inexpensive measuring unit is available as immersion fitting TA 40 or as fitting for installation in fittings as 2 ¼" and 2 ¾".
