What to pay attention to when infrared thermometers are connected
- 2019-03-12-

Infrared temperature measurement technology plays an important role in the production process in product quality control and monitoring, equipment online fault diagnosis and safety protection, and energy conservation. In the past 20 years, non-contact infrared human body thermometers have developed rapidly in technology. When using an infrared thermometer , what problems should be paid attention to during wiring? Today Wuxi very Xiang Technology Co., Ltd. takes you to understand:

A. After the connection between the thermometer and the wires is completed, the outlet hole bolts on the junction box should be tightened, and then the junction box is closed. The outlet hole of the junction box should be down to prevent water, dust, and stolen goods from falling into the junction box due to poor sealing;

B. The temperature in the infrared junction box should not be too high. Because the thermoelectric characteristics of the compensation lead are only in the range of 0-100 degrees (or 200 degrees), the thermoelectric characteristics of the infrared thermometer are consistent. Exceeding this temperature will cause additional errors, so the junction box should be avoided from the high temperature area during installation. . The usual practice is to bend the thermometer to a certain angle, keep the junction box away from heat sources, or cool the junction box with water to prevent the junction box from becoming too hot;

C. The connectors of the thermometer circuit (including the terminals and lugs in the junction box) will not affect the thermoelectric potential of the infrared thermometer circuit if the temperature is uniform. However, in many cases, due to the different heating conditions of the connector, the measurement error caused by the additional thermoelectric potential. In order to reduce this error, the connecting wire should be as close as possible to the hot electrode, and the two connectors connecting the positive and negative hot electrodes should be as close as possible, so that the two contact points of the compensation wire and the hot electrode are as consistent as possible.

The above are the issues that need to pay attention to when connecting the infrared thermometer.
