When using a 2-wire Pt100, the transmitter's terminals 3 and 4 are internally short-circuited, and the wire resistance to the Pt100 is as small as possible.
When the wire distance from Pt100 is long, use 3-wire PT100.
The working temperature is -20 ~ +60 °C.
When the load is 500Ω, the 4-20mA line resistance should be less than 80Ω; when the load is 250Ω, the 4-20mA line resistance must be less than 80Ω.
When the Pt100 input range is 100°C, the temperature coefficient is ≤250ppm/K FS
When the Pt100 input range is greater than 150°C, the temperature coefficient is ≤150ppm/K FS
Current output type temperature transmitter such as 4-20mA output, load resistance with 1% accuracy, 0.5 watt metal film resistors can basically meet the requirements.
However, it is necessary to adjust the two potentiometers on the transmitter to correct them accordingly, because the 1% accuracy resistor itself has a large error.
Left potentiometer: zero potentiometer, clockwise -> increase, counter clockwise -> decrease.
Right potentiometer: Amplitude potentiometer, clockwise -> decrease, anti-clockwise -> increase.
