392 Industrial Conductivity Transmitters Product Description

The industrial conductivity transmitter is a 4-wire 4-20 mA conductivity transmitter enclosed in a 1/8 DIN aluminum mounting enclosure.  The industrial conductivity transmitter has an isolated 4-20 mA output with display on a large LCD screen powered by 115/230 VAC.  The conductivity transmitter has selectable conductivity values from 19.99 uS/cm to 199.9 mS/cm via internal dip switch and jumper settings.  The industrial conductivity transmitters use a 10k thermistor for 5 to 55°C values for automatic temperature compensation.  The industrial conductivity transmitter connections are made with terminal blocks via spade lug connectors.

Global Water’s GL500 Conductivity Recorder adds recording capabilities to the conductivity transmitter.  The GL500 Conductivity Recorder connects to the conductivity transmitter’s 4-20mA output to record data.  In addition, Global Water offers the PC320 Conductivity Controller to use the conductivity transmitter’s output to control pumps or alarms.
