Tg Ul Series Wall And Duct

TG UL Series Wall and Duct

Senva Dual Toxic Gas Sensor and Controller

Senva TG UL Series wall and duct sensors can be ordered as individual sensors or as any dual combination of CO / NO₂/ CO₂/ Methane / Propane / Hydrogen / Oxygen / H2S / Ammonia / Refrigerants sensor in a shared enclosure.

The analog output model features two 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.
