CL 3630 Transmitter for Free Chlorine and Dissolved Oxygen TEXT SIZE: A A A    PRINT THIS PAGE   EMAIL THIS PAGE

The CL 3630 is a 4/20 mA Isolated Transmitter for Free Chlorine and Dissolved Oxygen Systems


CL 3630
Chlorine - Dissolved Ozone 4/20 mA Transmitter


· 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

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.
