    Tips for installing the non-contact infrared temperature sensor

    1. According to the measurement requirements and the measurement coefficient of the infrared temperature sensor, select the appropriate distance and orientation, and fix the infrared temperature probe and the adjustment bracket well.
    2. Adjust the measurement direction of the probe so that the measured object is roughly facing the observation site.
    3. Lock the orientation of the adjustment bracket.

    Question for linear relationship
    We recently purchased a few High Temperature Pressure Transducers for measurement ranges of 0-2.5MPa, 0-10 MPa, and 0-20MPa, each with an output signal of 4-20mA. Is there a calibration curve that correlates the output signal to the measured value or is it just a linear relationship with 4mA being equal to a pressure of 0 which increases linearly up to 20mA being equal to the maximum measurement range of that specific sensor?

    ATO Responded
    The range and output signal of these pressure sensors are only a linear relationship, 4mA is equal to 0 pressure, and linearly increases to 20mA.
