Temperature monitoring device

Abstract

The invention discloses a temperature monitoring device, which comprises a heat isolation device, a data collection module and a data processing module, wherein a tested object is arranged outside theheat isolation device; the data collection module is arranged inside the heat isolation device and is used for collecting temperature signals of the tested object and converting the temperature signals into thermoelectromotive force signals; and the data processing module is connected with the data collection module and is used for converting the thermoelectromotive force signals into the temperature value. The temperature monitoring device has the advantages that through the arrangement of the heat isolation device, the temperature of the data collection module is kept below 60 DEG C, so that the electric characteristics of the data collection module are ensured; and the monitoring on the temperature in various high-temperature environment can be realized.

Description

technical field [0001] The invention relates to the field of high temperature measurement, in particular to a temperature monitoring device. Background technique [0002] At present, in the field of high temperature measurement, the main measurement methods are contact measurement and non-contact measurement. Infrared thermometers are widely used in non-contact measurement. Monochromatic infrared thermometers are usually affected by dust and light in the environment, and are rarely used in practice; Thermometers are widely used, but most of them are all-in-one and need to be hand-held manually. Although it increases portability, it has strict requirements on the operation of the inspectors. Once the angle deviates, it will cause a large deviation in temperature; therefore, Infrared thermometers have relatively large limitations in the face of long-term high-temperature monitoring, and are not suitable for use in this environment. The contact thermometers mainly include the...

Infrared thermometers are widely used in non-contact measurement. Monochromatic infrared thermometers are usually affected by dust and light in the environment, and are rarely used in practice; Thermometers are widely used, but most of them are all-in-one and need to be hand-held manually. Although it increases portability, it has strict requirements on the operation of the inspectors. Once the angle deviates, it will cause a large deviation in temperature; therefore, Infrared thermometers have relatively large limitations in the face of long-term high-temperature monitoring, and are not suitable for use in this environment

The contact thermometers mainly include thermal resistance thermometers and thermocouple thermometers. Traditional contact thermometers often need to directly contact the temperature measuring element with the measured object, and process and display it at the measurement position ( Measuring and display all-in-one machine), but in the actual high temperature environment, the temperature will be too high (maybe as high as 400 ℃), and the temperature measuring element will not work properly when it is applied to some high temperature environment
