Differential pressure transducer: Precise measurement for building automation

What types of measurement pressure are there?

There are several types of measured Pressure, which occur frequently in different applications. The most common are differential pressure, relative pressure (also known as an overpressure) and absolute printing. Knowing the specific type of pressure to be measured is of crucial importance for the selection of the suitable pressure sensor or converter and the exact interpretation of the pressure measurement values. You will find an explanation of the individual printing types below.

What is the difference between differential pressure, relative pressure and absolute pressure

The main difference between an absolute pressure measuring shape and a differential pressure measuring former is the reference point against which the Pressure is measured. The following texts and graphics illustrate these differences. In it are P0 = vacuum pressure, P1 = atmospheric pressure and p = Pressure (measured at the point where you want to measure).

  • What is a differential pressure measuring former?

    A differential pressure converter is a pressure sensor or converter that serves between two points in a liquid or gas system to measure the pressure difference. It converts the adjacent pressure difference into an electrical signal that can be used for monitoring, control or data acquisition purposes.

  • How does a differential pressure measuring former work?

    A differential pressure transfer measures the pressure difference between two points in a fluid or gas system. It consists of three main components: a pressure sensor element, a signal preparation circle and an output group.

    Here you will find a simplified explanation of the functioning of a differential pressure measuring former:

    1. Pressure sensor element: As with a differential pressure transfer, the pressure -sensitive element of a differential pressure trans segment captures the pressure difference between two points in the system. It usually uses membranes, stretching strips or other sensor technologies that are responding to the adjacent Pressure deform.
    2. Disagination and strength compensation: The pressure sensor element turns proportionally to the differential pressure, which creates a weight of the strength. This deflection is used to the mechanical Pressure to convert it into an electrical signal.
    3. Signal preparation: The electrical signal generated by the pressure sensor element is prepared with the help of signal preparation circuits. This circuit can include amplifiers, filters, linearization techniques and other components to improve the accuracy, stability and linearity of the signal.
    4. Output group: The prepared electrical signal is converted into a standardized output signal, e.g. B. a 4-20-MA current or a 0-10 V voltage signal that can easily be transferred to a control system, a data acquisition device or an advertisement. The output signal represents the measured differential pressure.
    5. Calibration and adjustment: Similar to a differential pressure transfer, a differential pressure measuring shape is calibrated to ensure precise measurement. In the calibration, the output signal of the measurement converser is set so that it matches exactly with known pressure differences. Some measurement conversers have calibration options or adjustment mechanisms for the fine -tuning of the output.

    By measuring the differential pressure and its conversion into an electrical signal, the differential pressure transformer provides a reliable and proportional representation of the pressure difference between two points in the system. This information is crucial for monitoring, controlling and automating various processes in industries from HLK to manufacturing.

A differential pressure measuring form, as the name suggests, measures the pressure difference between two points in a fluid or gas system. He calculates the pressure difference by the Pressure At a point with the Pressure Compared to another point. It does not provide the absolute pressure value, but focuses exclusively on the difference between the two measured pressures.

The relative pressure, also called overpressure, is the measurement of the pressure in relation to the atmospheric Pressure Or a certain reference pressure. It represents the difference between the actual Pressure and the reference pressure.
