Abstract

The invention provides a temperature and pressure cooperative measuring device. The device comprises a thermometer, a pressure sensor and a jacket which is used for being communicated with a process pipeline; the measuring end of the thermometer is inserted into the jacket; one side of the jacket is provided with a pressure guiding pipe communicated with the jacket; and the measuring end of the pressure sensor is inserted into the pressure guiding pipe. A fluid working medium in the process pipeline is guided into the jacket, the thermometer and the pressure sensor measure the temperature and the pressure of the fluid working medium at the same time and the same position, the accuracy and the reliability of measured data are guaranteed; the structure of the device is simple; the device just occupies small space; and the installation and implementation of the device are convenient.

Description

technical field [0001] The invention relates to the technical field of temperature and pressure measurement, in particular to a temperature and pressure coordinated measurement device. Background technique [0002] In liquid air energy storage technology, temperature and pressure measurement are extremely important for system testing, status monitoring and automatic control. On the one hand, a temperature difference of 1K at low temperatures can cause large Accurate measurement can feed back the thermodynamic parameters of the working fluid to the central control system, which is convenient for parameter correction; on the other hand, timely temperature and pressure data feedback can start the chain stop device when the system is under abnormal working conditions. [0003] Traditional temperature and pressure measurements usually use separate thermometers and pressure sensors, and two holes need to be opened at a certain distance on the equipment or pipeline. When it is ne...
