Ceramic Heater Quality Identification

ceramic heating plate is a common electric heating element, made of ceramic as the main raw material. It has the advantages of uniform heating, stable high temperature, corrosion resistance, stable performance, etc., and is widely used in various fields. The working principle of

ceramic heating sheet is to convert electrical energy into thermal energy, and produce a heating effect through the high temperature characteristics of ceramics. After the power supply is connected to both ends of the heating element, the current passes through the resistance inside the ceramic heating plate to generate heat, causing the surface temperature of the heating element to increase.

Zhongke Testing provides ceramic heating chip quality appraisal services.

ceramic heating piece quality identification can be analyzed from the following aspects:

1. Appearance inspection The appearance of
ceramic heating piece is the first step to judge its quality. Check whether the surface of the ceramic piece is smooth and has no obvious scars and flaws; check whether the edges are neat and free of cracks and scratches; check whether the wiring joints are firm. At the same time, consumers should pay attention to whether the certification mark and related parameter information are clearly visible.
2, resistance test
resistance test is one of the important indicators of whether the ceramic heating piece is working properly. Before testing, turn off the power and allow the ceramic piece to cool down naturally. Then use a multimeter to perform a resistance test. Generally speaking, the resistance value of the ceramic heating piece should be between 50-100 ohms. If it is outside the range, it means there is a problem with the ceramic piece.
3, temperature test
In addition to resistance test, temperature test is also one of the important judgment criteria. Before testing, first connect the ceramic heating piece to the power supply, set the temperature and time according to the instruction manual, and let it run for a period of time. Use a linear thermometer to test whether the surface temperature of the ceramic piece reaches the temperature value indicated in the instruction manual and whether the temperature is evenly distributed. If the temperature value does not meet the standard, or the temperature distribution is uneven, it indicates that there is a quality problem with the ceramic sheet.
