About Honeywell SmartLine STG800
ST800 Dual Head Gauge Pressure Transmitters are suited for applications requiring small flange or 1/2 NPT connections. Typical applications include gauge pressure measurement of reaction vessels in the chemical industry and level applications with process temperatures of up to 302F /150C.
In-Line transmitters are screwed directly onto a 1/2 male NPT nipple and can be installed in hazardous environments for accurate, repeatable pressure measurement. Typical applications include high-pressure measurement in boilers, fuel feeds and high-pressure reaction vessels in the petrochemical and hydrocarbon recovery industries.
