Vendor NewsDetcon, an IST Company, is pleased to announce that its environmentally bulletproof TP-700 hydrogen sulfide MOS gas detector is now certified SIL 2 capable. The device recently underwent stringent functional safety assessments by third party agency exida and was found to be in compliance with IEC61508 : 2010 Parts 1-7.

The Model 700’s rugged framework includes an electro-polished 316 stainless steel housing with fully encapsulated electronics and dual layer surge protection. These details in design virtually eliminate the threat of outside damage to internal components due to water ingress, corrosion, vibration and transient spikes.
Sensor elements are simple plug-in components for easy replacement in the field while operator interface is user friendly via a small handheld magnet. Configuration and routine calibration are intuitive and menu driven with fully scripted instructions. The intelligent transmitter module features dual redundant outputs; a linear 4-20 milliamp analog signal and a Modbus RS-485 serial output. Product options include a Remote Alarm Module (RAM), HART, Foundation Fieldbus, and wireless. Additional approvals include CE, ATEX, CSA, CEPEL and GOST.
