HBProducts | Safety / Leakage Detection | Gas Alarms| NH3
Product Series: HBGS
HBGS exist in five versions ranging from 0-100 ppm and up to 0-15 %. The most sensitive sensors are suited for detection in cold stores where it can detect very small amounts of ammonia before it harms the frozen goods, and the less sensitive versions fulfils the requirements for gas leakage measurement in accordance with F-GAS regulation EU/517/2014.
The five versions are:
- 0-100 ppm
- 0-300 ppm
- 0-1000 ppm
- 0-5000 ppm
- 0-15 % (1-100% LEL)
All sensors in the ppm range are based on 3-electrode electrochemical gas sensor cells and the one in the percentage range is a catalytic cell. for the detection of Ammonia, and all must be supplied with 24 V DC. All has 3 built-in digital alarm outputs and one analog 4-20 mA output. The sensor can be set up using a PC with the HB Configuration Tool. The sensor element has a lifetime of 2 years and 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 comes with a calibration certificate as well as preconfigured alarm limits. Verification during the lifetime can be done with high gas concentrations. The sensor can be used in areas where cleaning solvents are used. A built-in heating element ensures the functionality down to -30 ° C ambient temperatures.
