DG-TT7-S with MOS H2S sensor receives SIL 2 approval
Tyco Gas & Flame Detection is pleased to announce that the DG-TT7-S H2Sgas detector with Metal Oxide Semiconductor (MOS) sensor underwent stringent functional safety assessments by an external certification body and is now SIL 2 approved.
The DG-TT7-S is solid-state metal oxide semiconductor (MOS) gas detectors used mainly for the detection of hydrogen sulphide (H2S) in arid locations having air present or in locations with continuous H2S background. The sensor specifies a wider continuous operating temperature range than the standard electrochemical sensors up to +65 °C.
