What type of temperature transmitter is suitable for measuring temperature in such situations?
Thread Content
The company’s cooking tower is equipped with a platinum resistance temperature sensor at the outlet where the material is ejected by the jet pump; such sensors cannot be installed elsewhere. It is common for the platinum resistance sheath to wear out, resulting in inaccurate temperature readings. It works normally after replacing the platinum resistor.
This has little to do with the temperature transmitter; it mainly depends on where the temperature measurement point is located. If the instructions regarding the protective sleeve are not followed and the temperature measurement point is installed in the wrong place, its location should be changed.
A wear-resistant armored thermoresistor can be used instead.....
The temperature measurement point needs to be wear-resistant; this is true provided that the location of the measurement point cannot be changed. If the location of the measurement point can be altered, then it is possible to consider changing the measurement approach. In fact, when it comes to thermometers, choosing a good measurement method is more important
Consider improving the wear resistance of the protective sleeve; talk to the manufacturer to see if there are sleeves made from materials with enhanced wear resistance
The main reason is that the flow velocity of the medium at the ejector’s outlet is too high, resulting in erosion wear.
Casing damage is a common occurrence; due to factors such as flow velocity, corrosion, and erosion, it is sufficient to strengthen the material and thickness of the protective tube surrounding the thermoresistor. While it’s impossible to guarantee that the casing will never get damaged, it will definitely be in much better condition than before! As for how to make a decision, it’s best to explain the situation to the manufacturer and communicate with them!
