Sensor Termination Box (STB)

ATEXCSAEU Conformity (CE)Det-Tronics Point IR Termination Box (PIRTB) FM Approval

Sensor separation and termination solution

When your gas monitoring requirements include a flexible, cost-effective means of terminating a combustible sensor and other 4-20 mA devices, the STB is the perfect solution. Also, the STB can be used to separate the sensor and transmitter/display where installation requirements dictate separation. 

Models are available to accommodate Det-Tronics catalytic combustible gas sensors (CGS), C706X electrochemical sensors (retired), GT3000 gas sensors, as well as components of the Eagle Quantum Premier® (EQP) System.
