  • Maintenance of pressure sensors

    1. What is a sensor At present, the sensor that people say is composed of two parts: a conversion element and a sensitive element. Among them, the conversion element refers to the part of the sensor that converts the measurand felt or responded by the sensitive element into an electrical signal s...

  • Four-wire and Two-wire system of Pressure transmitters

    Most of the transmitters are installed on site, and their output signals are sent to the control room, and its power supply comes from the control room. There are usually two ways of signal transmission and power supply for the transmitter: (1) Four-wire system The power supply and the output sig...

  • Advantages of Digital Pressure Sensors

    To get the highest possible pressure sensor accuracy, you need an output signal that is not easily damaged and has a very high resolution. 1. Reduce signal loss and interference The digital output signal is not subject to signal loss or interference like an analog signal, otherwise the intact sig...

  • What is the temperature drift of the pressure sensor

    What is “warm drift”? Under the interference of external factors, the output of the sensor will usually change unnecessarily, which is independent of the input. This kind of change is called “temperature drift”, and the drift is mainly caused by the sensitivity element of ...

  • Pressure hysteresis of a pressure sensor

    As an important component of a pressure transmitter, the sensor has three important indicators that can determine whether a pressure transmitter can perform the measurement task well, they are: pressure hysteresis, pressure repeatability, and stability. Each transmitter must be tested and adjuste...

  • Urea sensor

    The front part of the urea pressure sensor is used to detect the urea pressure, and the rear part is responsible for detecting the mixing pressure of urea and air in the mixing chamber. When the component fails: the urea consumption is abnormal, and the vehicle lights the fault light. When the fa...
