Rõhulangumõõturid

Rõhulangumõõturid, or pressure transducers, are devices used to measure pressure in fluids, gases, or other materials. They convert the pressure into an electrical signal, which can then be interpreted and displayed by an instrument or control system. There are several types of pressure transducers, including:

Piezoresistive transducers: These use the piezoresistive effect, where the resistance of a material changes in response to applied pressure. They are known for their high accuracy and linearity.

Strain gauge transducers: These operate on the principle of strain gauges, where a thin film of material is bonded to a substrate. When pressure is applied, the substrate deforms, causing a change in resistance that can be measured.

Capacitive transducers: These use the change in capacitance of a device to measure pressure. They are known for their high sensitivity and linearity.

Piezoelectric transducers: These use the piezoelectric effect, where a material generates an electric charge in response to applied mechanical stress. They are often used in high-frequency applications.

Resonant transducers: These operate on the principle of resonance, where the frequency of a vibrating element changes in response to applied pressure. They are known for their high sensitivity and low power consumption.

Pressure transducers are used in a wide range of applications, including industrial process control, automotive, aerospace, and medical devices. They are chosen based on factors such as the range of pressure to be measured, the required accuracy, the operating environment, and the specific application requirements. Proper calibration and maintenance are essential to ensure the accuracy and reliability of pressure transducers.
