SGF100

Conventional stand-alone sensor for different types of gas, wall and attic. IP64

The stand-alone sensor SGF serie has the prerogative to control through sensors catalytic technology the presence of Gas Methane. The sensor is managed by a microprocessor, which not only supplies an alarm signal to the control unit connected to it, but also allows execution of a self-diagnosis and therefore an automatic calibration, in order to always have the maximum detection accuracy.

The self-calibration allows the probe to adapt in difficult environments and variable temperature avoiding false alarms due to anomalous events. Furthermore with this sensor it is possible:

1) To select the working range to 20% of the LEL or 100% of the LEL

2) To select the positive safety of the relaye

Test: to perform a precise and self-certified test, use the TS1008 instrument, which also serves to carry out the annual check.
