The GSM-05 gas detector

The GSM-05 gas detector is used to detect the under-explosion-hazardous combustible vapor concentrations, flammable liquid vapors and their mixtures of the IIA, IIB, IIC categories and Т1, Т2, Т3, Т4 types. It is installed in the explosion hazardous zones indoors and outdoors, as well as on the open-air fields. Two types of sensors are used: thermochemical sensor and solid-state sensor. Controlled environment temperature range varies from - 60 °С to +50 °С. Functions: the remote combustible gas sensors can be located up to 1000 meters from the detector (if the resistance of each conductor is not more than 15 Ohm); the current combustible gas concentration value is indicated on the front panel of the gas detector; the adjustment, calibration, control and measurement mode of the gas detector are accessed using the in-built keyboard; warning light glows when the limit concentration value of the components from 0 to 50% of the lower explosive limit (LEL) is reached; two alarm thresholds are formed: Threshold 1 and Threshold 2; the alarm threshold levels are set by the software; to avoid a breakdown, the sensor power is interrupted if the gas concentration limit is reached.
