Important auxiliary parts in high and low temperature alternating test chambers

When users buy high and low temperature alternating test chambers, they probably look at compressors, control instruments, heating systems, etc. at first glance, but do you know that some small auxiliary parts need us to pay more attention to them? Otherwise, the security of the device may not be guaranteed. Some users may feel a little alarmist, don't worry, and listen to Xiaobian and then tell you.

The function of the temperature limiter in the high and low temperature alternating test chamber is to implement the second protection for the over temperature in the tank when the temperature of the controller is out of order. When an alarm occurs, the shutdown will be protected, and the alarm will vary with the test temperature. The corresponding changes can be made to effectively protect against over-temperature protection. The principle is that when the current flowing through the fuse exceeds the limit, the temperature of the fuse rises and fuses, and when the heat generated by the fuse does not exceed its rated capacity, the temperature of the fuse does not reach the melting temperature. It won't break.

The leakage protector of the high and low temperature alternating test chamber not only turns the main circuit on or off like other circuit breakers, but also has the function of detecting and judging leakage current in the high and low temperature alternating test chamber, when leakage occurs in the main circuit or When the insulation is broken, the leakage protection switch can turn on or off the switching element of the main circuit according to the judgment result. It cooperates with fuses and thermal relays to form a fully functional low-voltage switching element.

Now that you know, some of the gadgets in the high and low temperature alternating test chamber may play a big role!
