Smart Gas Transmitter 1X Series BI 500

Bhoomi BI500 – 1X Series Smart Gas Transmitter is a Single Gas Transmitter comprising of transmitter and sensor which detects Flammable, Toxic and Oxygen gas present in Industrial & Commercial premises and provides Audio and Visual alarm indication for Industrial and Human safety. It is designed to use hazardous & non-hazardous area.

It is 3 wire transmitter with 4-20 mA, Modbus and Relay output. Electrochemical, Infrared and Pellistor technology based sensors used for detection of Flammable, Toxic and Oxygen gases. 1.8” TFT Graphic LCD Display provides information about gas type, concentration, unit, alarm set point, temperature and time.

The transmitter enclosure has three threaded entries. The two cable/conduit entries either side of the upper part of the transmitter housing are for connecting the power source, signal output and relay contacts to associated signalling equipment. The bottom entry allows direct connection of the sensor socket.
