CL 3630 Transmitter for Free Chlorine and Dissolved Oxygen

Brand: Van London Company

The CL 3630 is a 4/20 mA Isolated Transmitter for Free Chlorine and Dissolved Oxygen Systems.
Features
  • The transmitters incorporate a large LCD display which is easily readable even from considerable distances.
  • Transmitters are powered by an external power supply from 10 to 30 Vdc. The same two wires which provide power to the transmitter also carry the 4/20 mA output signal.
  • The 4/20 mA output is isolated from the input.
  • The isolation allows the connection to PLC, DCS or Personal Computers accepting 4/20 mA signals.
  • The transmitter will display temperature and the temperature coefficient values of manual/automatic temperature compensation.
  • The automatic temperature compensation is achieved with the use of a Pt100.
  • Detachable terminal blocks and Din Rail mounting enclosure provide for easy field installation.
  • Two wire 4/20 mA operation
  • Isolated current loop output
  • Potentiostatic, polarographic and galvanic sensors input
  • LCD display
  • Temperature and TC display
  • Automatic or manual temperature compensation
  • 10/30 Vdc power supply
  • Direct connection to PC's
  • Din Rail mounting
  • Detachable terminal blocks
