Why do you need a temperature rise test / Heating cycle test ?
The parts that can be touched when the product is working, if the temperature is too high, it may cause personal injury; In addition, excessive temperature inside the equipment can also affect the performance of the product, and even lead to a decrease in the insulation level or increase the mechanical instability of the product. Therefore, in order to ensure that the product can work safely and stably, it is very necessary to test the temperature rise of the product.

The purpose of the temperature rise test
 / Heating cycle test
The temperature rise test / heat cycle test set is one of the important tests for the safety performance of electronic and electrical products, which is used to evaluate the quality and electrical safety characteristics of electrical products. During normal use, due to the heating of some high-current components, the temperature rise of the electrical product itself is too high, and working in this state for a long time may reduce the performance of the insulating material, resulting in electric shock, scalding or fire danger of the equipment. Temperature rise tests / Heating cycle test are an important way to detect and avoid these dangers.

Temperature rise test method
The temperature rise test method can be divided into two categories: non-contact and contact according to the different measuring temperature instruments.

1. Non-contact measurement method
The non-contact measurement method can measure the temperature expressed on the outside of the measured object, and the real temperature can only be obtained by correcting the emissivity of the measured surface of the problem, and the measurement method is affected by the distance between the measured object and the instrument, as well as other media such as water vapor, smoke, and dust on the radiation channel, so the measurement accuracy is low. The methods we often use in daily life include spectral temperature measurement technology, holographic interferometric temperature measurement technology, and CCD-based trichromatic temperature measurement technology.

2. Contact measurement
Contact thermometer temperature probes generally have two types: thermocouple and RTD:
The working principle of thermocouples is based on the Seeback effect, two conductors of different compositions are connected at both ends to form a loop, and if the temperature of the two connected ends is different, a thermal current is generated in the loop, and the temperature is measured by using this phenomenon.
The measurement principle of RTD is to measure the temperature according to the characteristic that the resistance itself changes when the temperature changes.
In the contact test method, the temperature measuring element is in direct contact with the measured medium to directly measure the temperature of the measured object, so it is simple, reliable and has high measurement accuracy.
