Tyco Gas & Flame Detection is pleased to announce that the DG-TT7-S H2S gas 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.
The device supports HART 7 protocol option for full configuration and diagnostics over non-proprietary interface. The MultiTox DG-TT7-S features on board relays, plug and play sensors and a high visible display that changes colour depending on the status mode.
