From a simple 4-point monitoring system to a complete plant wide hazardous gas monitoring system with hundreds of gas detection points, Sentry meets the need.

PC-based DCS software in conjunction with Sentry provides the operator enhanced data acquisition, alarming and alarm management, historical trending, distributed architecture, and integration into the plant’s distributed control system. Sentry’s Modbus communication interface provides over 620 different parameters accessible by the PC-based DCS software, including: gas concentration alarm setpoints sensor diagnostic messages historical reset time/date power up/down time/date trouble alarm time/date minimum/maximum values plus time/date high/low alarm latch/non-latched auto calibration enabled calibration status/coefficients calibration concentrations calibration due date zone option enabled operate mode Using the optional FieldServer Technologies Gateway the user can convert from the Modbus RTU output to a wide variety of other protocols including DF1, DH+, Profibus, Modbus TCP, ControlLogix and many more.
