First of all, it depends on the temperature measurement module, which is fast, accurate and stable. According to the experience of our customers for more than ten years, imported thermometers are still the first choice.
Secondly, the principle of temperature algorithm and PID is not difficult, but it is difficult for manufacturers to have a lot of product data experience to support the algorithm. The process parameters of each product are different, and the manufacturer should have a database to support the algorithm.
Finally, it depends on whether the manufacturer is the original research manufacturer or the agent manufacturer. Those with independent development ability will definitely be the first choice.
