Hydrogen Gas Detection
The HGD-2000is Hydrogen Gas Detector allows the user to monitor hydrogen gas buildup in storage rooms and facilities that house batteries. The HGD-2000is is easy-to-use and easy-to-install. The detector has color-coded wires for connection to single-phase AC power source and two internal alarm relays. The relays can be used to switch a remote exhaust fan and/or alarm on and off. If the concentration of hydrogen gas in the air surrounding the sensor reaches 1% by volume, the yellow LED will light and the 1% internal relay will close. A four second delay prevents false activation. If the concentration reaches 2%, the red LED will flash, the internal 80 db warning alarm will sound, and the 2% internal relay will close.
This HGD-2000is model is designed to be intrinsically safe and meets the requirements for either Class I Division I or Class I Division II areas. The NFPA also has a new system that uses Zones in Chapter 505. This detector also meets the requirements for Zone 0 AEx ma ia IIC T6.
