    RS485 output wiring diagram

    Note: For the output signal RS485, it is only a 485 communication protocol, if you need the data to be received from the PC through the RS485 port, then the PC used should be a PC for industrial application, which can support 485 communication function (such as touch screen HMI upper computer, etc.), A USB to 485 communication interface is also needed to connect the sensor to the PC.

    Tips: Selection of pressure sensor sensitivity
    Generally, within the linear range of sensor, it is better that the sensitivity of pressure sensor is as high as possible. Only when the sensitivity is high, the value of output signal corresponding to the measured change is relatively large, which is conducive to signal processing. However, it should be noted that if the sensitivity of pressure sensor is too high, the external noise which is irrelevant to the measurement is easy to mix in, which will also be amplified by the amplification system, thus affecting the measurement accuracy. Therefore, it is required that the digital pressure sensor itself should have a high signal noise ratio to minimize the interference signal introduction from the outside.
    The sensitivity of digital pressure sensor is directional. When the measured object is a single vector and has high directional requirements, the sensor with low sensitivity in other directions should be selected. If the measured vector is a multi-dimensional vector, it is better to select the digital pressure sensor with smaller cross sensitivity.

    Pressure range of digital pressure sensor
    We are needing pressure transducers for continuous pressure measurement, gage type. Water and air pressure transducer pressure range: -0.1~0-0.02~100MPa. Do you proivde?

    Unfortunately, don't provide, as the pressure of 100Mpa is too high, our pressure sensor supports only up to 60Mpa.
