    Temperature Transmitter, PT100/E/K/S/B/T/J/N/R Type

    5 out of 5 based on 1 reviews | Write a review
    Temperature transmitter adopts 2-wire transmission mode. Temperature transmitter converts PT100 RTD sensor and E/K/S/B/T/J/N/R type thermocouple signal to 4-20mA output signal that is linear with the input electrical signal or the measured temperature. Head mounted temperature transmitter can be installed in the protection head of the thermocouple and RTD sensor to form an integrated structure. DIN rail temperature transmitter can be installed in the control cabinet.

    Tips: Temperature transmitter calibration

    1. Calibrate the temperature transmitter on site, particularly the transmitter with thermocouple input. If there's automatic temperature compensation for reference end, the compensation lead method shall be adopted for connection calibration. When calibrating, the output impedance of the calibrator shall be smaller enough than the input impedance of the calibrated thermocouple temperature transmitter, otherwise a large measurement error may occur.
    2. Adjustment before calibration. Use the method of changing input temperature signal to adjust the corresponding output lower limit value and output upper limit value, make it consistent with the lower and upper limits value of the standard. Do not adjust zero and range during the measurement process.
    3. Calibration process. Selection of the calibration points is evenly distributed by measuring range. Generally no less than 5 points shall be selected, including the upper limit, the lower limit and the points near the 50% range. Read and record in turn from the lower limit to the upper limit and then reverse to the lower limit, measure for three cycles. Calculate the difference between the average value and the standard output value of the calibrated points within the 3 cycles through the comparison method, thus getting the error of all the calibrated points.

    My questions about temperature transmitter
    Hey good day Im looking for a thermocouple and a transmitter for it. Do you have any low powered solutions? The desired ranges are: Temperature range: -20ºC to 185ºC. The output signal can be either: 4-20ma or 0-10v (the first one is better for us) and a power consumption of 5v if possible I know it might not though, thank you.

    We can customize the temperature transmitter to be with a 5V power supply, but it can only output 0-5V signal.
