Industrial Process and Sensor: Honeywell Models 811 FMA and 811 FMG Pressure Transmitters

The Two Wire Factory Mutual Approved Models 811 FMA and 811 FMG transmitters have welded, stainless steel diaphragms for use with liquid, gas, or corrosive vapors. Both models have hermetically sealed, stainless steel cases which require no adjustments. These transducers are corrosion and shock resistant, as well as reverse polarity protected. The two wire 4-20mA output permits cable runs up to 10 miles long with high signal to noise ratio. Model 811 FMG utilizes our proprietary “true gage” design. A dual pipe thread pressure fitting is provided for easy bulkhead mounting.
