Pressure Transmitter with Pressure Relief

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

A true "relief" transmitter is uncommon; protection is typically achieved by installing a mechanical relief valve or bursting disc upstream. When system pressure exceeds a safe set point, the valve opens to divert excess fluid, preventing sensor diaphragm rupture. Some designs include internal overload stops that tolerate burst pressures up to 10× the rated span for brief transients. Units with vent ports also release trapped air or condensate from impulse lines-essential in steam or viscous fluid services to avoid hydraulic locking. Manifold blocks with isolation and equalizing valves permit safe transmitter removal under full line pressure. Pressure transmitter with pressure relief combined approach enhances plant safety, reduces unplanned outages, and prolongs transducer life. Found in high‑pressure hydraulic presses, wellhead monitoring, and steam distribution networks, pressure transmitter with pressure valve must be positioned close to the tap point for rapid actuation. Periodic testing of the relief mechanism guarantees continued set‑point accuracy.

Pressure Transmitter with Pressure Relief is found in high-pressure hydraulic presses, wellhead monitoring, and steam distribution systems. Prevents sensor damage from sudden pressure spikes. Also used in pipeline pigging operations and high-pressure gas storage, where mechanical relief valves vent excess pressure to protect both the transmitter and the overall system integrity.

Integrated overload stops tolerate burst pressures up to 10× rated span. Vent ports release trapped air or condensate to prevent hydraulic locking. Manifold with isolation/equalizing valves enables safe removal under pressure. Mechanical relief valve upstream diverts excess fluid, protecting the sensor diaphragm from sudden spikes and extending service life.
