INDUSTRIAL MEASUREMENT & CONTROL
ST 3000® Gauge Pressure Transmitters
For High Temperatures
Field Instrument Solutions
ST 3000® Transmitters for High Temperatures can withstand process temperatures in excess
of 300 degrees Fahrenheit (150 degrees Celsius). Designed to measure pressure or the level
of fluid in open or non-pressurized tanks, these unique transmitters can replace troublesome
capillary-filled remote seal systems to yield better overall accuracy, much greater stability,
and substantially reduced installation and maintenance costs. A patented sensor provides
high-temperature performance and functionality.
