Overview
Dual Head Gauge Pressure Transmitters are suited for typical applications involving reaction vessels in the chemical industry and level applications with process temperatures up to 257°F /125°C.
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.
The following models are available:
