What device automatically stops the operation of the pressure-imposing element when a certain pressure or temperature is reached?

The pressure-limiting device is designed to monitor and control the pressure within a system, automatically ceasing the operation of a pressure-imposing element when a predetermined pressure threshold is reached. Its primary function is to prevent overpressure conditions that can lead to equipment failure or safety hazards. By halting operation at specific pressure levels, it helps to maintain a safe operational environment and protect both the system and personnel.

Other options may refer to different mechanisms with distinct functions. For example, a pressure-relief valve is intended to release pressure when it exceeds a safe limit, rather than stopping operation. A pressure-imposing device is involved in applying pressure but does not have the same safety control function. The term pressure-relief device can encompass various mechanisms but typically focuses on venting excess pressure rather than managing operational stoppage when a preset limit is reached.
