Honeywell ST3000 Honeywell Smart Absolute Pressure Transmitters

Honeywell Smart Absolute Pressure Transmitters

Absolute pressure transmitters are used primarily in applications where the pressure being measured is less than standard atmospheric pressure such as a suction or vacuum application. These devices provide a linear analog output signal pressure measured relative to absolute zero. The temperature of the media being measured is very important as the fill fluid used in the transmitter may boil at levels well below their normal boiling point.

Smart transmitters have the benefit of adjustable measuring span or range within specified limits. These units can be re-ranged in the field or instrument shop with hand-held communication tools and/or pressure standards. To select the appropriate model, determine the pressure range of the media being measured, identify the temperature of the media being measured, understand the corrosive nature of the media, and consider the mounting of the unit for practical installation, calibration and maintenance of the unit.
