Senva TG Series refrigerant sensors are a great solution for refrigerant leak detection in many applications. It can be ordered as individually calibrated R134A or R410A sensors or any combination with CO or NO2 sensors in a shared enclosure. Buy pre-calibrated for R134A or R410A or factory calibrate to any refrigerant including R134A, R410A, R407C, R404A, R22, R123.
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.
Refrigerant leak detection in mechanical rooms
Pre-calibrated for R134A or R410A or factory calibrate to any refrigerant including R134A, R410A, R407C, R404A, R22, R123
(1) One side transformer secondary is connected to signal common. Dedicated transformer is recommended. No mains circuit connection allowed. In addition, it is required to use an isolated power supply that is certified by a national or international standard (i.e. UL). Use of a Class 2 LPS power supply or greater is required.
(2) R134A sensor is factory calibrated to R134A gas but may be used as a general purpose refrigerant sensor. Sensitivity to other gases can be found in the installation manual or Refrigerant Cross Sensitivities document. Actual response may vary depending on installation. For more accurate response to a specific gas, a unit may be field calibrated.
