Description

Technical Field

[0001] The utility model belongs to the technical field of waste gas treatment, and in particular relates to a temperature and pressure integrated sensor. Background Art

[0002] The thermometer reaches thermal equilibrium through conduction or convection, so that the indication of the thermometer can directly represent the temperature of the object being measured. Generally, the measurement accuracy is high. Within a certain temperature measurement range, the thermometer can also measure the temperature distribution inside the object. The pressure sensor is a device or device that can sense the pressure signal and convert the pressure signal into a usable output electrical signal according to a certain rule. The pressure sensor is usually composed of a pressure sensitive element and a signal processing unit. According to different test pressure types, the pressure sensor can be divided into a gauge pressure sensor, a differential pressure sensor and an absolute pressure sensor. The temperature sensor and the pressure sensor are usually installed separately on the detection equipment. The split installation method not only increases the installation steps, but also fails to detect the temperature and pressure at the same place. The detection data will be biased. Therefore, the inventor proposes a temperature and pressure integrated sensor. Utility Model Content
