Senva TGW-ACX-AW : Wall Mount Toxic Gas CO Sensor/Controller, 0-10V, 0-5V, 1-5V and 4-20mA Selectable Output, LCD Display, All White Solid Enclosure, 7-Year Warranty

Senva UL Listed TG Series sensors can be ordered as individual CO or NO2 sensors or as a combination CO/NO2 sensor in a shared enclosure. 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. The BACnet/Modbus model supports BACnet MS/TP & Modbus network communication in one unit. Standard features include network auto-configuration, a programmable fan relay, LED indicators, integrated display and audible alarm.

APPLICATIONS

  • Ensure adequate air flow in occupied spaces
  • Ideal fo parking lot garages 
  • Monitor multiple toxic gases with one mounted unit
  • Alert occupants of elevated gas levels
  • Directly control exhaust fans
