CX105 Loop-Powered 4-20mA Conductivity Transmitter

CX105 Loop-Powered 4-20mA Conductivity Transmitter

Our CX105 conductivity transmitter is an isolated output 4-20mA industrial transmitter for reading contacting conductivity sensors. The CX105 transmitter also measures Resistivity and TDS. Easily power the unit with available two-wire power supply loop. This transmitter is ideal for connecting to a PLC for advanced control systems. The CX105 has versatile mounting options for wall or panel mount. With a dual display LCD, monitoring both the measuring value and the temperature is simple.

• Dual display shows the measuring value and temperature

• Compatible with a wide variety of contacting conductivity, resistivity, and TDS sensors

• One year limited warranty

• CE certified – compliant with European Community Standards
