What should we be guided by when choosing a thermal converter? The design features of the place of use and the temperature range of use can affect the ability to use a particular model of the sensor. We recommend that you take into account the following criteria for the optimal selection of a thermal converter: Correspondence of the measured temperatures to the operating ranges of the sensors. Note that contact thermocouples are designed for much higher temperatures than RTDs. For example, when measuring the temperature of water, thermoresistances with a copper sensitive element operating in the range from -50 to 180 ° C are used; and when measuring higher temperatures, thermocouples TChK (chromel-copel), TCA (chromel-alumel) and TLC (iron-constantan) are used. Access class. Consider the required measurement accuracy, the permissible conversion error depends on the operating temperature range. The need for an explosion-proof design for work in explosive areas. For example, when measuring in highly dusty rooms, as well as in gas-polluted places where there is a possibility of explosion, a thermal converter with the Ex marking is used. Correspondence of the strength of the sensor housing to the operating conditions. Length of the immersed part of the sensor. It is recommended to immerse the sensor approximately two thirds of its length in the medium to be measured. Length of the connecting cable. Compliance of the overall connection characteristics with the seat requirements. When choosing, it is necessary to have drawings of the seat, since thermal converters are produced with various design features - diameter and thread pitch, diameter of the immersion part, etc. © 2005-2014 PK Forward-Komplekt LLC.
