Pressure measuring techniques can be used to measure not only process or differential pressure, but also level, volume, density or mass flow in all areas of process technology.
The measuring ranges of pressure transmitters start at a few mbar and extend to extreme pressures up to 1000 bar. Different measuring cells are used in these pressure instruments.
VEGA pressure transmitters deliver high-precision readings in gases, vapours and liquids.
DCM – as industry specialists – provides expert-knowledge in pressure measurement solutions for even the most difficult applications.
Pressure transmitters measure the pressure of liquids, gases and vapours in pipes or closed vessels. The pressure of the measured medium acts on a pressure measuring cell, which converts it into an electronic signal.
The process pressure transmitters are ideal for detecting the relative or absolute pressure in applications with condensation or rapid temperature changes.
The measuring cell of the pressure transducer detects minute changes in hydrostatic pressure, which increases or decreases depending on the filling level. The acting pressure is converted into an output signal by the integrated electronics.
Ceramic-capacitive and metallic measuring cells are used to detect the pressure in hydrostatic pressure measurement.
In differential pressure measurement, different pressures act on an oil-filled, pressure difference measuring cell from two sides. The instrument converts the pressure differential into an electronic signal.
Pressure, level, density and flow of liquids, suspensions, gases and vapours can be measured using the principle of differential pressure.
