When designing the temperature sensor installation, due to the different product characteristics and installation location, when installing the temperature sensor, you will encounter this or that problem. For example, the installation position of the temperature sensor will affect its corresponding speed and the seal of the probe installation. Sex, sensor installation is simple or complex, temperature probe shell material selection, etc., these will affect its performance and service life, only properly installed the temperature sensing device, select the probe shell material, in order to accurately measure temperature, accurate count.
In the product structure design, the installation of NTC temperature sensor (probe) has always been the most concerned issue for engineers' friends. How to install temperature sensor effectively? In fact, the best method is to design your product with a variety of styles, sizes, and models of sensor housings that can be provided by temperature sensor manufacturers.
The response speed of the NTC temperature probe depends on the material of the probe housing, the wall thickness of the probe housing, the thermal conductivity of the epoxy adhesive, the size of the NTC head, and so on. In water with high thermal conductivity and relatively low thermal conductivity, the response speed is different. The difference in the inside diameter and outside diameter of the protection tube does not affect the response time.
When installing the NTC temperature sensor, pay attention to the mechanical strength. In particular, pay attention to the location where the installation is not allowed to have moisture so as to prevent the NTC thermistor chip from being penetrated by the moisture in the probe seal. In addition, in order to avoid the thermal loss of the protection tube will affect the temperature of the component, it also needs to consider the flow direction and protection tube insertion length, shape, heat insulation, thermal insulation and other issues.
In addition, it should also be noted that during installation, temperature sensors should be installed in a location that is as representative as possible. Avoid installation at dead angles, avoid strong magnetic fields or heat sources, and reduce the impact of external factors on the results. Moreover, the temperature sensor is preferably installed vertically to prevent deformation due to high temperatures and a very good installation location for the pipe bends. Also pay attention to the hygienic protection and post-maintenance of the temperature sensor to ensure that the sensor can work properly.
