Usually used in conjunction with display instruments, recording instruments, electronic computers, etc. Directly measure the temperature of liquid, vapor, gas media, and solid surfaces within the range of -200~500 ℃ during the production process.
·Pressure spring type temperature sensing element with good anti vibration performance;
·High mechanical strength and good pressure resistance.
Thermistor measures temperature by utilizing the characteristic that the resistance of a substance changes with temperature. When the resistance value changes, the working instrument displays the temperature value corresponding to the resistance value.
The basic structure of assembling thermocouples mainly consists of junction boxes, terminal blocks, protective tubes, insulation sleeves, and thermoelectric electrodes, and is equipped with various installation and fixing devices
Note: t is the measured temperature * * * value of the temperature sensing element.
thermal response timeT0.5
When there is a step change in temperature, the time required for the output of the thermocouple to change to 50% of the step change is called the thermal response time, represented by τ 0.5.
Nominal Pressure
Generally refers to the static external pressure that the protective tube can withstand at working temperature without breaking. In fact, work pressure is not only related to the material, diameter, and wall thickness of the protective tube, but also to the structure, installation method, insertion depth, and flow rate and type of the medium being used for the thermocouple.
*Less depth of insertion
Thermocouples with a minimum insertion depth of 8-10 times the outer diameter of their protective tube (except for special products)
Room temperature insulation resistance
At an ambient temperature of 15-35 ℃, a relative temperature not exceeding 80%, and a test voltage of 10-100V (DC), the insulation resistance of platinum resistance should not be less than 100 M Ω· m; the insulation resistance of copper resistance should not be less than 50 M Ω
