Combustible gas detector has Hart communication for industrial applications

01 July 2008

General Monitors’ S4000C combustible gas detector is now available with Hart communications. The new Model S4000CH is suitable for demanding industrial applications where the potential presence of dangerous hydrocarbon-based combustible gas is a threat.

Gas monitor with Hart compatibility

Hart permits remote process variable interrogation, cyclical access to process data, parameter setting and diagnostics. Unlike other protocols, Hart is backward compatible with the installed base of instrumentation in use today.

The S4000CH is suitable for use in SIL 3 applications and approved by FM, CSA, ATEX, GOST and has CE Marking. It is also available with an optional relay configuration that is appropriate for SIL 2 processes
The S4000CH reliably monitors combustible gas and vapors within the lower explosive limit (LEL) and provides status indication and alarm outputs. It is equipped with relay contacts that can be used to indicate an alarm or fault condition and dual redundant Modbus or Hart communication.
