NH3 Gas Leakage Alarm/Sensor

Technical data: HBGS

HBGS fulfils the requirements for gas leakage measurement in accordance with F-GAS regulation EU/517/2014. HBGS detects
NH3 (R717) in a range of 25… 500 ppm. It is an independent unit that must be supplied with 24 V DC. It has 3 built-in digital alarm outputs and 1 analogue 4… 20 mA output. The sensor can be set up using a PC with the HB Configuration Tool.


The sensor differentiates itself from other sensors on the market by having a measuring head that remains stable in the longterm (thick film metal oxide semiconductor type). The sensor element can easily be replaced. On the front, you can find 4 integrated LEDs for display of the supply (green) as well as 3 alarm levels (red, orange, and yellow). Similarly, there is a reset button in case an alarm is triggered. The sensor is factory calibrated and does only require additional calibration in special applicationwith high gas concentration. The sensor is optimized for use in areas where cleaning solvent are used. Built-in heating element ensures low ambient temperatures down to -20 ° C.

The sensor comes with a calibration certificate as well as with preconfigured alarm limits.
