Toxic Gas Transmitter TGT 1000
TGT 1000 is a series of direct use Sensor + Transmitter combination units housed in weather-proof (IP65) enclosures.  Transmitters are designed for standard two-wire operation where the output is supplied via the same wire pair as the power supply. The external circuit loop is connected to the transmitter via a screw terminal Connector.The  Units  are  supplied  pre-calibrated  for  the  specified range, and the sensitivity of the device should not drift by more than 2% of full signal per month. Some sensors have cross interference effect of  other gases. It is important to specify air composition to help choose appropriate sensor.Except  requiring  periodic  re-calibration,  transmitters  are maintenance-free,    and    should   give faultless service throughout the working life of the sensor.TGT is available with  many    optional enhancements like 4 digit  LED  display,  multi-parameter back  lit LCD  display. HART  protocol  output.  Modbus  protocol,  PC  calibration and programming facility etc.
