Sierra Monitor Corporation

Sierra Monitor offers products in two primary categories or the hydrocarbon processing industry. The gas and flame detection product line provides state-of-the-art hazardous gas management systems for plant-wide monitoring of hazardous gases including combustible gas, toxic gases and oxygen deficiency.  With Modbus output, central alarm controls, and non-intrusive calibration, Sentry has been the system of choice for years.

The Communications Bridge product line is also a leader in its field. The Communications Bridge is the only multi-channel product capable of translating from several different protocols with the same device and providing Ethernet access and hot standby for redundant application needs. Link old or new PLCs, SCADA and control devices to each other or the Ethernet backbone easily with the Bridge.
