ABB Model 9437 Low and High Level Dissolved Oxygen Monitor


The 9437 Series transmitter provides the operator interface and communications to other devices. The signal from the sensing system is converted by the transmitter and the information is presented on a large, custom-designed, easy-to-read, backlit liquid crystal display (LCD) as a μg/kg or mg/kg value.

A process retransmission signal and two alarm relay outputs are provided as standard, while an optional RS485 serial interface allows the transmitter to be easily incorporated into the ABB PC30, or other Modbus™ compatible supervisory system.

Available in wall-mounting or 1/4 DIN panel-mounting versions, the transmitter is protected to IP66, ensuring reliable operation in the most demanding situations. The same level of protection is maintained during programming and calibration.
