Fixed co gas leak detector with relay output to start the ventilation system
Our QB2000 is used for car test.
When you test the car, a lot of excessive co will be produced, to keep the good air quality,and keep worker safe in the test room, online fixed co gas leak detector with relay output is necessary to start the ventilation system.
Gas leak detector with relay output 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.
Features of gas leak detector:
1.4-20mA analog output for direct communication to DCS system
2.Relay output for connecting external device
3.User-selectable alarm setpoint(s).
4.Sensor module(block) design on -spot replacement s and automatically distinguish sensor fault and current display fault simultaneously.
5.Password verification for repeat operation, avoid fault operations.
6.-40~+70℃ following compensation for accurate detecting.
7.Second grade visual alarms on-site and Relay(connected with audible/visual alarms or drive exhaust device).
Our QC auditors perform aging test for continuously 48 hours strictly to ensure quality before shipping
With relay output, once the concentration exceeds the preset alarm point(threshold) it will start the acoustic-optical alarm on the central unit and drive the external equipment like exhaust fans to dilute the co gas concentration.
