In the gas detection for tough environments, an innovative alternative which compares the signals received from two different sensors (Pel+IR) installed in a single head setting the improper alarms apart.
The Sensitron (Italy) 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 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.
The other important features of the SMART S-IR are: a non-intrusive calibration; 3 wires 4-20mA output with a further two relays output and the HART communication module (optional).
The SMART S-SS and the SMART S-MS belong to the same family. The SMART S-MS is a double-head detector and two different sensors (Pel-IR; IR-IR; Pel-Electrochemical; Electrochemical-Pel) can be installed on it. It guarantees two different independent outputs and can be compared. The detectors are SIL 2(3) certified in compliance with EN50402/EN61508.
