Description

Product Description

The Senva TGW-AHX-A is a wall and duct sensor that can be ordered as an individual sensor. The analog output model features two outputs that support daisy chain wiring. 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.

  • Cost-effective dual gas sensing and control
  • Flexibility of analog output model
  • Versatility with BACnet/Modbus model. High reliability reduces callbacks

Product Highlights

The Senva TGW-AHX-A is easy to install and has a 7-year warranty. It has an LCD display and selectable output.
