Description

Medium cavity and medium cavity covering part

Technical Field

The utility model relates to a temperature measurement technical field, concretely relates to medium chamber and medium chamber covering.

Background

In the thermal industry, calibration of temperature sensors is an important item, and it is necessary to calibrate more temperature sensors in the shortest possible time and to protect the equipment used. In calibrating the temperature, a standard mercury thermometer is usually used as a standard, a large amount of media, such as high-purity industrial alcohol, purified water or specified oil, is stored in a medium cavity such as a constant temperature bath, and the temperature sensor is placed in the medium cavity such as the constant temperature bath for calibration. The existing covering part of a medium cavity such as a thermostatic bath is usually a stainless steel cover, and the cover is opened when in use and covered to reduce the loss of the medium when not in use. Frequent opening or closing of a media chamber such as a temperature sink can present the following problems: 1. part of the medium such as alcohol and the like is volatile, so that the medium is lost; 2. the temperature difference between the inside and the outside of the medium cavity can influence the uniformity of the temperature in the medium cavity when the medium cavity is opened or closed; 3. frequent opening or closing can bring the problems of complicated operation steps and inconvenient operation.

When the sensor is calibrated, the whole covering part needs to be opened for the sensor which can be immersed in liquid, and then the sensor is placed in a constant temperature groove; for the sensor which can not be immersed in liquid, a glass tube is fixed on a cover part of the thermostatic bath, a temperature sensor is put into the glass tube, and an opening on the glass tube is sealed by cotton.

The calibration work of the temperature sensor has certain drawbacks: firstly, a large amount of media need to be stored in medium cavities such as a thermostatic bath in use to maintain the temperature of the medium cavities, and in the process of using the media for a long time, if the temperature is at a high point or a low point during calibration, the media are easy to volatilize, which leads to the increase of the cost of the media, and meanwhile, impurities can enter the medium cavities such as the thermostatic bath to influence the temperature uniformity and the fluctuation degree of the medium cavities. Secondly, after the calibration process is finished, when the sensor is taken out, a large amount of medium can be remained on the sensor, so that a large amount of medium can be lost, and after the sensor is taken out, the sensor can be placed everywhere.
