H2 SENSOR KIT-030-040
H2 sensor kit for GC oven
This H2-SENSOR Kit 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 6940.00.055 controller reads the percentage of Hydrogen measured by the sensor 6940.00.070 and, if the value exceeds the threshold alarm, the Controller deactivates the solenoid valve in the 6940.00.056 block. The alarm can be signaled to a PC and to a remote device.
Sensor 6940.00.070 is engineered to work in standalone mode connected by RS-485 network to a Hydrogen Generator. The sensor can be connected directly with the LNI 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.
