GAS DETECTOR WITH
REMOTE SENSOR
RFG 361
C1 Eng.
• Remote sensor for detecting methane, propane-LPG, carbon monoxide (CO)
• Sensors with sensing element specific for each type of gas
• 1 SPDT voltage-free output relay
• Adjustable alarm threshold (for methane and propane-LPG)
• Self-diagnosis sensor fault
• Construction and operation according to
CEI EN 50194 and CEI EN 50244 for Methane and Propane LPG
CEI EN 50291 and CEI EN 50292 for CO - carbone monoxide
• Installation on DIN rail; Protection IP 40
• Power supply 230 V ~
1. APPLICATION
RFG 361 is designed for the detection of gas in spaces such as: boiler rooms, laboratories, workshops, garages.
parking silos.
According to the type of sensor connected, monitors the concentration in air of the following gases: methane,
propane-LPG, carbon monoxide.
The sensors used are selective, and so are not influenced by gases other than that for which they are dedicated.
They have the following characteristics:
– methane and propane-LPG: sensors with semiconductors rendered selective by means of special filters,
– carbon monoxide (CO): the sensor is an electrochemical cell with two electrodes specific for CO.
The detector provides as outputs a pre-alarm signal and an alarm signal
• exceeding the pre-alarm threshold is indicated visibly by a flashing light.,
• exceeding the alarm threshold is indicated by visible and acoustic warnings and, by means of an output relay,
permits making an operational intervention such as, for example:
– closing a N.C. shut-off valve,
– closing a N.O. shut-off valve,
– switching on an aeration fan,
–sending an alarm signal to a remote site.
