Temperature-pressure sensor

Abstract

The sensor includes a body case composed of a probe head and a cavity connected to the head, as well as a temperature-sensing element, four pieces of pressure sensor, a temperature-sensing circuit and a pressure induction circuit, which are setup inside the cavity. There is a mounting hole on an end face of the probe head; and the temperature-sensing element is setup on the mounting hole. There are four holes in intervals for liquid to flow in or out on the end face of the probe head; and pressure sensors are set up at these holes respectively. The disclosed temperature - pressure sensor simplifies manufacturing structural technique. Parameters of temperature and pressure are collected at same position so as to guarantee position identity of measured point. It is in favor of carrying out interfusion and compensation of data of each parameter.

Description

technical field [0001] The invention relates to a temperature and pressure sensor which integrates temperature sampling and pressure sampling. Background technique [0002] The sensor is an important part of the industrial control system. The existing sensor measurement technology is very mature, and the measurement indicators are constantly improving. However, a sensor can only measure one parameter, and the measurement of more physical and chemical signals and multi-parameter signals In terms of measurement, the signal types and functional coverage are very narrow, which is far from meeting the growing needs of the development of automatic monitoring technology. In engineering, it is often necessary to measure multiple parameters at one location. For example, in the application field of diesel engines, it is often necessary to measure the temperature and pressure of the exhaust port at the same time. If a separate temperature sensor and pressure sensor are used to measure ...

[0002] The sensor is an important part of the industrial control system. The existing sensor measurement technology is very mature, and the measurement indicators are constantly improving. However, a sensor can only measure one parameter, and the measurement of more physical and chemical signals and multi-parameter signals In terms of measurement, the signal types and functional coverage are very narrow, which is far from meeting the growing needs of the development of automatic monitoring technology

In engineering, it is often necessary to measure multiple parameters at one location. For example, in the application field of diesel engines, it is often necessary to measure the temperature and pressure of the exhaust port at the same time. If a separate temperature sensor and pressure sensor are used to measure these two physical quantities at the same time, usually in the Punching holes on the pipeline increases the number of openings, and it is difficult to ensure the identity of the measured point position, which is not conducive to data fusion and data compensation of various parameters
