Platinum Resistance Temperature Detector PT1000M213B -M213 Thin
Film Platinum Resistance Series PT1000B
At 0 degrees Celsius, the resistance of PT1000 is 1000 ohms, and
its resistance increases at a constant rate as the temperature
rises. pt1000 is a platinum resistance thermometer, and its
resistance value is directly proportional to the change in
temperature. The resistance value of PT1000 and its temperature
variation relationship are as follows: When the temperature of
PT1000 is 0℃, its resistance value is 1000 ohms, and at 100℃, its
resistance value is approximately 1385 ohms.
The resistance value and temperature of a metal thermal resistor
can generally be expressed by the following approximate
relationship, that is, Rt=Rt0[1+α (t-t0)], where Rt is the
resistance value at temperature t. Rt0 represents the resistance
value corresponding to temperature t0 (typically t0=0℃). α is the
temperature coefficient. The relationship between the resistance
value of a thermistor and temperature is Rt=AeB/t, where Rt
represents the resistance value at a temperature of t. Constants A
and B depend on the structure of the semiconductor material.
The temperature ranges are different. PT1000 is suitable for
measuring small-range temperatures, while PT100 is suitable for
measuring slightly larger-range temperatures
The reaction sensitivity of PT1000 is higher than that of PT100.
When the temperature of PT1000 changes by one degree, its
resistance increases or decreases by approximately 3.8 ohms. When
the temperature of PT100 changes by one degree, its resistance
increases or decreases by approximately 0.38 ohms
The pt1000 differential sampling bridge circuit is used for
measurement. The voltage at one end is basically constant. When the
temperature changes, the voltage output of the pt1000 will also
change. After the variation is amplified by op07 and sent to the
adc for sampling, the corresponding voltage value can be obtained.
Based on the voltage value, the temperature can be calculated.
There are also cases where pt100 and resistors are directly
connected in series, and the partial voltage is calculated to
convert the temperature value. This method can achieve good
accuracy within a relatively small temperature range, basically
within 0.5 degrees.
