NTC thermistor temperature thermocouple sensor installation and application requirements

by:JVTIA     2020-11-10
Thermocouple temperature sensor installation in the design, because the product features and installation location, at the time of installation of thermocouple temperature sensor will encounter this or that problem, for example: temperature thermocouple sensor installation location will affect the speed, the corresponding probe installation of sealing, thermocouple temperature sensor installation simple or complex, probe the choice of shell material and so on, these will affect the performance and service life, only properly installed temperature sensing device, select the probe shell material, can accurate temperature measurement, accurate count.

in the product structure design, the NTC temperature thermocouple sensors ( The probe) Installation has been the most concern of the engineer friends, how easy, convenient and effective temperature thermocouple sensors installation? In fact is the best way to combine your product temperature thermocouple sensor manufacturers can provide all kinds of style, design specifications, models of thermocouple sensor shell.

in the case of NTC temperature sensor response speed depends on the probe of shell material, probe the shell wall thickness, the thermal conductivity of epoxy resin adhesive properties, the size of the NTC head size and so on. The water in the large thermal conductivity and thermal conductivity, relatively small in the air, the speed of response is not the same. Protecting tube inner diameter and outer diameter of different will not have an impact on response times.

the NTC temperature thermocouple sensors installed mechanical strength should be paid more attention to, especially should pay attention to the location of the installation are not allowed to have water in order to avoid the probe filling and sealing moisture permeability damage the NTC thermistor chip. In addition, in order to avoid the protection tube heat loss will affect the temperature of the element, you also need to consider the flow and the protecting tube insertion length, appearance, heat insulation, thermal insulation, and other issues.

in addition, you should also note that when temperature thermocouple sensors installed, should choose the typical installation location, as far as possible to avoid blind Angle installation, avoid the strong magnetic field or heat source, reduce the influence of external factors on the results. Vertical installation, and the temperature thermocouple sensors can best prevent because of the high temperature deformation, pipe bend very good installation location. Also, pay attention to the temperature of the thermocouple sensor and health protection and maintenance, to guarantee the normal work of the thermocouple sensors can be.
