What does the thermal resistance pt100 mean?

The thermal resistance PT100 means that its resistance value is 100 ohm at 0 degrees, the negative 200 degrees is 1852 ohm, at 200 degrees is 17586 ohm, and 800 degrees is 37570 ohm.
The thermal resistance formulas are expressed in the form of RTRO1ATBTTRTRO [1ATBTTCT-100TTT].
PT100 Temperature sensor Celsius temperature RO is the resistance value of zero -degree Celsius. ABC is a specified coefficient, which is equal to 100 for PT100RO.
 
The main technical parameters of the thermal resistance PT100 temperature sensor are as follows < /strong>
Measurement range-200 ~ 850 allows the deviation △ ℃
A -Class 015+0002 | T | B -Class 030+0005 | T | Thermal response time 30s minimum depth heat,
The minimum depth of the resistance is ≥200mm, the Yun pass current ≤5mA, in addition, the PT100 temperature sensor also has the advantages of good anti -vibration stability accuracy and high pressure.

When you see that the current cannot be greater than 5mA, the resistance is to change with temperature, so the voltage should be noted.
In order to improve the accuracy of the temperature measurement, the 5V reference power supply of the 1V bridge power AD converter should be used to stabilize at the 1MV level. Under the condition of price permitted, the linearity of the PT100 sensor AD converter and the op amp must be high. = At the same time, the use of software to correct its error can make the accuracy of the measurement temperature at ± 02,
PT100 means that its resistance value is 100 ohm at 0 degrees PT100 temperature sensor . It is a resistor -type temperature sensor made of platinum PT. The relationship is as follows RRO LAT.
PT100 temperature sensor's main technical parameters are as follows
Measurement range -200 ℃ ~ 850 ℃ allows the deviation value △ ℃ △ ℃ A-level soil 015.
+0002 | | T | B -Class 030+0005 | T | Thermal response time
current ≤5mA Another PT100 temperature sensor also has the advantages of anti -vibration stability, good accuracy and high pressure.
