High Temperature Explosion Proof Pressure Transmitter

Shanghai Zhaohui Pressure Apparatus Co., Ltd. is one of the leading manufacturers and suppliers of high temperature explosion proof pressure transmitter in China, also supports customized service and 1 year warranty. Welcome to wholesale bulk durable high temperature explosion proof pressure transmitter in stock here from our factory.

High temperature explosion proof pressure transmitter is purpose-built with a two-stage heat dissipation tower comprising radial cooling fins and a thermal barrier gasket, which actively reduces heat transfer from the 400°C process media to the sensitive piezoresistance die. The capillary line is filled with high-stability silicone oil formulated with low thermal expansion coefficient, minimizing volumetric changes that cause false readings. An optional remote diaphragm seal with extended flexible hose can distance the electronics up to 5 meters from the heat source, enabling measurement in furnace flues or cracking coil outlets. The internal micro controller runs a proprietary temperature correction algorithm using three independent RTD sensors, dynamically adjusting zero and span every 50 milliseconds. The housing uses heat-reflective paint and stands-off mounting brackets to avoid direct heat radiation from adjacent pipelines. Certified for Class I Division 1, high temperature explosion-proof pressure transmitter operates reliably in continuous 250°C ambient conditions near unfired process heaters. Key installations include sulfur recovery units, reformer reactors, waste incinerators, and plastic extrusion dies.

High temperature explosion proof pressure transmitter is used in pharmaceutical ferments, dairy pasteurizers, breweries, and cosmetic cream mixers. The sanitary connection allows quick dismantling for CIP/SIP sterilization, meeting FDA and 3A standards for bacteria-free measurement in edible oil, vaccines, and juice production.

Two-stage heat sink with cooling fins isolates electronics from 400°C media. Multi-point RTD compensation corrects thermal drift. Remote seal option distances sensor from extreme heat. Reflective coating resists radiant furnace temperatures.
