The craft engineer of a large chemical manufacturer was difficult to hold. The response time of their process temperature sensors is often poor, and the reason cannot be figured out at all. The response time for temperature changes is always nearly 30 minutes longer than the due time, but all system diagnostic tests indicate that the sensor instrument is fine. After checking everything they could think of, the engineer contacted the supplier of the temperature sensor and explained the problem. However, the technicians of the well -known instrument manufacturer cannot explain the abnormal lag of the resistance temperature detector sensor. Keep in mind that temperature control is essential in almost all chemistry processes, and half an hour lag is a serious problem.

 

In order to seek solutions, the factory's control system engineer consulted Vendon's temperature experts. In just a few minutes of conversation, Velian's temperature experts were very sure that he knew the problem. He had heard of this lagging problem before: it was almost always related to the medium that had no actual contact with the tip of the sensor. It usually needs to be directly contacting between the tip of the sensor and the process of the media or the storage tank to obtain the near -time temperature reading. Any type of gap between the tip and the surface to be tested can cause the heat to be transmitted before the sensor. After the factory was checked, the initial suspicion of the temperature expert was confirmed. The length of the temperature sensor is not enough to reach the bottom. This leads to a delay in reading.

 

The RTD temperature sensor loaded with a spring solves the problem of delay

TR10 Industrial temperature sensor

 

Weilina's temperature engineering team recommends that the RTD (resistor temperature detector) component loaded by the spring is the best way to ensure that the tip of the sensor reaches the inner bottom of the ultra -deep heating sleeve. Weilian provides three spring loading sensor component samples for the maintenance team of the factory. They have passed all tests and seamlessly connected to the factories' distributed control sensor (DCS). The performance of the new temperature sensor is perfect.
