H2 Sensor


OPT.H2.SENS.2 is a security system that constantly detects the amount of Hydrogen present in the GC’s oven and blocks the Hydrogen generation if it detects an amount greater than the safety threshold.
The OPT.H2.SENS.RCV controller reads the percentage of Hydrogen measured by the sensor OPT.H2.SENS.2 and, if the value exceeds the threshold alarm, the Controller deactivates the solenoid valve in the OPT.H2.SENS.VB.V2 block. The alarm can be signaled to a PC and to a remote device.

OPT.H2.SENS.2 is engineered to work in standalone mode connected by RS-485 network to a Hydrogen Generator. The sensor can be connected directly with the MicroPROGEL Hydrogen Generators.
When the hydrogen concentration detected exceeds a threshold of safety, the Hydrogen Generator automatically stops the production and audible and visual alarms will be reported.
