Gas Sensors Transmitter /Gas Transmitter/Combustible Gas Transmitter Approved By CCOE for IIA IIB & IIC Measured gases : All Combustible Gases , Hydrogen , CH4 Etc Applied Field proven gas Transmitters continuously monitors for dangerous concentrations of gases. The linearize 4-20 mA transmission can interface directly with any receiving instrument starting from indicators, controllers to large control systems. Provision for directly connection of buzzer/Hooter for Alarm through Relay. The standard system consist of a compact electronic module housed in a Weatherproof or explosion proof Metallic or Polyester box with an application specific sensor. This state of the art transmitter is carefully designed with and manufactured with Industrial grade Components for reliability accuracy and long life. It is certified for usein hazardous areas Class 1, Division 1, Group B, C & D. (IIA, IIB or IIC), IP 65 apart from being available in weatherproof Enclosure Transmitters are equipped with micro controller and are heavily featured with self diagnostics, Auto calibration (in case of toxic, O , combustible gases only) through embedded Software, can be done at site. RS 232/485 output with baud rates of 2400 bps is available as an options.
