Brief introduction:
Wall mounted oxygen gas leak monitor features range of 0-30%vol,it's designed to monitor oxygen gas concentration and sound an alarm.
With relay output, once the concentration exceed the preset alarm point(threshold) it will start the acoustic-optical alarm on the central unit and drive the external equipment like exhaust fans.
It has been widely used in petrol, chemistry, metallurgy, artifice, gas transportation, biological medicine and water procession etc.
Characteristics:
◆4-20mA analog output for direct communication to DCS system
◆Relay output for connecting external device
◆No display screen
◆Sensor module(block) design on -spot replacement s and automatically distinguish sensor fault and current display fault simultaneously.
◆Password verification for repeat operation, avoid fault operations.
◆ -40～+70℃ following compensation for accurate detecting.
◆ Second grade visual alarms on-site and Relay(connected with audible/visual alarms or drive exhaust device).
◆User-selectable alarm setpoint(s).
