Brief introduction:
Fixed carbon dioxide gas detector is mainly designed to
monitor carbon dioxide gas concentration and sound an alarm.
It detect CO2 gas by use of natural diffusion, not by pump.
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:
◆RS485 analog output for direct communication to central unit
◆Relay output for connecting external device
◆LED 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).
