Innovative Hybrid Technology for Gas Detection

摘要

Sensitron (Italy) has developed the innovative Hybrid gas detector, ATEX and SIL2 (3) approved. Among the gas detection instrumentation for tough environments an innovative alternative is now available, which compares the signals received from two different sensors (Pel+IR) installed in a single head setting the improper alarms apart. The Sensitron's SMART S-IR is an innovative concept in the gas detection for the Premium Safety market. The detector uses a hybrid technology sensor (Pel+IR) installed in a single head. The behaviour of the sensors is constantly monitored by a microprocessor and the incoming signals are compared in order to supply an output corresponding to the worst situation revealed in the shortest time: it guarantees the highest accuracy with false alarm conditions close to zero. Other important features of the SMART S-IR are: non-intrusive calibration; 3 wires 4-20mA output with a further three relay output and HART communication module (optional).
