There're a lot of hydrogen gas produced in the battery room.
But hydrogen gas leak should be controller for safety.
Hydrogen gas transmitter is used to monitor the concentration of hydrogen.
Hydrogen gas transmitter can sound an alarm by visual and audible signals to operators in the area where the leak is occurring, giving them the opportunity to leave.
It is important because there are many gases that can be harmful to organic life, such as humans or animals.
Characteristics:
◆Sensor types:electrochemical sensor
◆4-20mA analog output(3+ channel) for direct communication to DCS system and RS485 ModBusoutput
◆Sensormodule design on -spot replacement s and automatically distinguish sensor fault and current display fault simultaneously.
◆LED Display(LCD optional)
◆Password verification for repeat operation, avoid fault operations.
◆-40~+70℃ following compensationfor accurate detecting.
◆Second grade visual alarms on-site and Relay(connected with audible/visual alarms or drive exhaust device).
◆User-selectable alarm setpoint(s).
