Survemõõturid

Survemõõturid, also known as pressure gauges, are instruments used to measure the pressure of a fluid, whether it be a liquid or a gas. They are essential in a wide range of applications, from simple household appliances to complex industrial processes. The fundamental principle behind most pressure gauges is the use of a sensing element that deforms in response to pressure changes. This deformation is then translated into a readable pressure value, typically displayed on a dial or digitally.

One of the most common types of pressure gauges is the Bourdon tube gauge. This gauge utilizes a curved, flattened tube that straightens out when subjected to internal pressure. The movement of the tube is linked to a pointer that indicates the pressure on a calibrated scale. Diaphragm gauges and bellows gauges are other types that employ flexible membranes or corrugated tubes, respectively, to detect pressure variations. Digital pressure gauges offer a more modern approach, using electronic sensors to convert pressure into an electrical signal, which is then displayed numerically.

The applications of survemõõturid are vast. They are found in plumbing systems to monitor water pressure, in automotive engines to check oil and fuel pressure, and in manufacturing plants to control pneumatic and hydraulic systems. They are also critical in safety systems, such as those used in boilers and gas cylinders, where over-pressurization can be dangerous. The selection of a specific type of pressure gauge depends on factors like the pressure range, the medium being measured, environmental conditions, and the required accuracy. Regular calibration of these instruments is crucial to ensure their continued reliability and precision.
