Gas detector with replaceable sensor
BETA
BETA detectors warn the gas presence in the environment where they are installed with an
optical and acoustic signal. They are equipped with an output relay for controlling a solenoid
valve for intercepting gas.
After that period, an optical signal warns to replace the sensor, simply by removing a front plate
and using the sensors parts supplied in blister packs.

Standards certified: EN 50194
Power supply: 230 Vac – 50÷60 Hz and 12Vdc
Absorption: 4,5VA max (230Vac) - 2,5W (12Vdc)
Alarm level: 10% L.E.L. - Measuring range: 0÷20% LEL

Gas detector with acoustic alarm and output relay
GAMMA
The IMQ certification in accordance to the standards CEI EN50194 gurantees the perfect
working of these gas detectors.
In presence of gas concentration, the alarm spy is lighting, the buzzer emits a loud signal
and thanks to the output relay, it is possible to manage the closing of the solenoid gas
valve.
