The TGM-APX-A is a Senva TG UL Wall & Duct dual Combustible Gas Sensor/Controller. Senva TG Series sensors can be ordered as individual CH4 sensor, C3H8 sensor, H2 sensor, O2 sensor, H2S sensor, or specify two sensing elements in one enclosure including CO and NO2. The analog output model features 2 outputs that support daisy chain wiring - multiple sensors may be used in a parallel sequence (0-10V) for cost effective coverage of large areas. The unit can also act as a stand alone controller, utilizing the relay for exhaust fan operation or the output for direct control of a VFD.
