BI-PLANAR DIFFERENTIAL PRESSURE TRANSMITTER WITH ORTHOGONAL PROCESS CONNECTIONS

摘要

A pressure transmitter apparatus includes a unitary body with two, normally vertical pressure passageways communicating respectively between opposed pressure openings extending normally horizontally through the body portion. A transducer for generating a differential pressure signal mounts on a transducer element, coupled to the body portion and located above the pressure passageways. A pair of diaphragm elements can form first and second process diaphragms, closing first and second pressure openings. Flange elements overlie the diaphragm elements and are removably and replaceably secured to the body portion, having liquid drainage and gas purging passageways. An overrange protection element can be integrally arranged with the unitary body portion to protect the transducer from overrange pressure fluctuations. Extensions on the flange elements afford a variety of mounting options, including mounting to industry standard pipe mountings.
