Conductivity Sensor 4-20mA Transmitters

Sensorex currently offers a compact, low cost, loop-powered blind conductivity transmitter with a 4-20 mA output for use with contacting conductivity probes and model CT-1000. Also available is a loop-powered 4-20mA transmitter in 1/4 DIN box with a display and programmable ranges. Another transmitter available is the new TCSTX or TCSMA transmitter; it can be used with (toroidal) inductive conductivity sensors. These are perfect choices to use with your PLC, Data Logger, or other monitoring-control device requiring a 4-20 mA input.

CON500 4-20mA Conductivity Transmitter

The CON500 features microprocessor based technology and offers six user programmable conductivity ranges. Both conductivity and temperature are displayed simultaneously on the large LCD display. Out of range current indicator and current hold during calibration are just a few of the user-friendly programming features that come standard with this transmitter. The CON500 ranges allow for use of sensors with k=0.1, k=1.0, and k=10.0, a feature not possible with the CT-1000 (fixed range & k-factor).  Both "ZERO" and "SPAN" calibration adjustments are made via the easy-to-use membrane touch pad. The housing is a 1/4 DIN box with IP65 & NEMA4X rating that can be panel or wall mounted.

TCSMA 4-20mA Toroidal Conductivity Transmitter

The new TCSMA two-wire transmitter is designed for use with our TCS3020 series toroidal sensors. It is a blind transmitter (no display). DC power requirement is 16-35VDC and output is isolated 4-20mA. Download Specs for details.

TCSTX 4-20mA Toroidal Conductivity Transmitter

The new TCSTX two-wire transmitter is designed for use with our TCS3020 series toroidal sensors. It features a local display; DC power requirement is 16-35VDC and output is isolated 4-20mA. Download specifications for details.

CT1000 4-20mA Conductivity Transmitter

The model CT-1000 (encapsulated miniature transmitter) is a compact-sized two-wire, 4-20mA blind conductivity transmitter featuring encapsulated construction, high performance, and ATC. Connect a conductivity cell of k=0.1 or 1.0 then transform the output to a 4-20mA current proportional to the conductivity level. This output may be transmitted over two wires to a control location. The same two wires provide power to the transmitter. Any DC power supply from 12 to 36V DC may be used. There are two adjustments on the transmitter to standardize the conductivity output marked as "SPAN" and "ZERO". The output can be monitored with a loop-powered meter, a loop resistor, PLC, Data logger, or a multimeter during the standardization process. ATC is available when connected to a 10k NTC thermistor.
