Senva TGD-BNX-AS : Duct Mount Toxic Gas NO2 Sensor/Controller, BACnet MS/TP, Modbus RTU, Modbus ASCII Output, LCD Display, Solid/Opaque Enclosure, 7-Year Warranty

The Senva TGD-BNX-AS is a duct-mount toxic gas NO2 sensor/controller featuring BACnet MS/TP, Modbus RTU, and Modbus ASCII output, as well as an LCD display, all housed in a Solid/Opaque enclosure with a 7-year warranty. This device is particularly useful in ensuring adequate airflow in occupied spaces, making it ideal for applications such as parking lot garages. The TGD-BNX-AS can also alert occupants of elevated gas levels and directly control exhaust fans. The device features a 3-1/2 digit LCD display, LEDs for status indication, and an 85dB piezo transducer for audible alarm exposure. The NO2 sensor is electrochemical, with an accuracy of ±5% of the default range and a resolution of 0.1ppm. The sensor's life expectancy is greater than 7 years, covering an area of 5000-7500 square feet. The enclosure, suitable for both wall and duct installations, is made of ABS/Polycarbonate material and complies with UL61010-1 standards, being UL, cUL, and CE listed.

Applications

  • Ensure adequate air flow in occupied spaces
  • Ideal fo parking lot garages 
  • Alert occupants of elevated gas levels
