A pressure sensor is a mechanism which physical parameters changes depending on the pressure of the medium being measured. In the pressure sensor, the measured medium is converted into a unified pneumatic, digital code or signal.

What is a pressure sensor for?

Endress Hauser pressure transmitter is a device for measuring and converting the pressure of a medium - liquid, gas or steam. The resulting value is displayed or transmitted as an analog or numeric outlet beep. The principle of operation depends on the type of measured pressure, which can be absolute, gauge and differential.

The principle of its operation is to gauge the stress inequality betwixt two cavities - plus and minus. They can be used for flow metering, with the help of narrowing devices. The narrowing device in the pipeline is a local resistance, passing through which the nature of the flow changes.

Areas of use

Pressure sensors as devices that transform the measured importance into a single digital signal can be used in production (chemical, food, petrochemical, mechanic engineering, metallurgy, shipbuilding, energy) and for laboratory experiments.

Application of pressure sensors Endress Hauser:

  • Engineering
  • Shipbuilding
  • Control and measurement technologies
  • Hydraulics and pneumatics
  • Pumps and compressors
  • Transport
  • Utilities
  • Construction
  • Medicine

Types:

  • Optical sensors
  • Magnetic
  • Capacitive
  • Mercury actuators
  • Piezoelectric sensors
  • Piezo resonant detectors
  • Resistive

Optical pressure sensors have two construction methods: fiber optic and optoelectronic. Fiber-optic actuators have a very high accuracy and do not depend significantly on temperature conditions. The main sensitive element in such sensors is an optical waveguide. They can work in fluid and aeriform media, including aggressive ones.

Optoelectronic pressure sensors are made from complex multilayer transparent structures. Light passes through this structure. The parameters of the layers change, on the basis of which the pressure is calculated. Changing these and other parameters will change the properties of the transmitted light.

Magnetic sensors are based on E-shaped plates. In the structure of this system is a coil, and a pressure-sensitive conductive membrane.

Capacitive sensors are a capacitor with a variable gap. Capable of capturing very small changes in pressure, have high accuracy.

Mercury sensors work on the principle of communicating vessels. Press the measured pressure on one of these vessels. The pressure is determined by the value of the mercury column.

Piezoelectric pressure sensors are only suitable for measuring rapidly changing pressure. Lofty sensitivity of semiconductor strain gauges, high reliability and stability, technological compatibility with signal processing integrated circuits, miniature size of semiconductor sensitive elements, the possibility of using group manufacturing technology are their main advantages.

Piezo resonant sensors work on the piezoelectric result. This type of actuators uses a piezoelectric resonator, to which electrodes are applied on both sides. A voltage of different sign is alternately applied to the electrodes. The resonator frequency will indicate the amount of pressure exerted on the membrane.

Resistive tension detectors operate on the basis of a strain gauge, which is installed on a membrane that is sensitive to pressure changes. As a result, under pressure on the membrane, it bends and bends the strain gauges attached to it. Because of this, the resistance on them changes and the amount of current in the circuit changes.

Endress Hauser pressure switch

Endress Hauser produces three main types of Pressure measurement equipment:

  1. Pressure transducers for continuous measurement. Includes gauge and absolute digital pressure transmitters. The main lines: Cerabar and Ceraphant.
  2. Compact pressure sensors and probes to be used for hydrostatic level measurement. They use in water and other liquids. Main families: of E&H hydrostatic level transmitters: Deltapilot and Waterpilot
  3. Differential pressure sensors and transmitters. Thea are devices that are used in various fields to obtain pressure parameters. Measurements are made without interruptions, as a result, the parameter is transformed into an output signal of voltage or current according to the requirements of the Customer. The devices are also called pressure sensors.E&H series: Deltabar FMD and Deltabar PMD.
