HBProducts | Safety / Leakage Detection | Gas Alarms| CO2
Product Series: HBGS-CO2
HBGS fulfils the requirements for gas leakage measurement in accordance with F-GAS regulation EU/517/2014. HBGS detects CO₂ (R744) in a range of 0…10000 ppm. The sensor applies NDIR (Non-Dispersive Infra-Red) detection technique. This technique is based on the fact each gas has a unique and well-defined light absorption curve in the infrared spectrum that can be used to identify the CO₂ gas. The concentration can be determined by using a suitable infrared source and analyzing the quantity of energy absorbed from the gas inside the optical path.
It is an independent unit that must be supplied with 24 V DC. It has 3 built-in digital alarm output and 1 analog 4… 20 mA output. The sensor can be set up using a PC with the HB Configuration Tool. The CO₂ sensor version has a lifetime of more than 5 years. Both sensor elements can easily be replaced and does not require a new calibration. 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. Verification during the lifetime can be done with high gas concentrations. The sensor is optimized for use in areas where cleaning solvents are used. Built-in heating element ensures low ambient temperatures down to -30 ° C. The sensor comes with a calibration certificate as well as with preconfigured alarm limits.
