nyomatékmér

Nyomatékmér is a Hungarian term that translates to "pressure gauge" in English. It refers to an instrument used to measure the pressure of a fluid, typically a gas or liquid, relative to a reference pressure. These devices are essential in a wide variety of applications, ranging from industrial processes to everyday domestic systems.

The fundamental principle behind most nyomatékmérs is the detection of a force exerted by the pressure being measured. This force is then converted into a readable display, often a dial with a needle or a digital readout. Common types of nyomatékmérs include Bourdon tube gauges, diaphragm gauges, and digital pressure sensors. Bourdon tube gauges utilize a curved tube that straightens when subjected to internal pressure, moving a pointer. Diaphragm gauges use a flexible membrane that deflects under pressure, which is then mechanically amplified. Digital sensors often employ strain gauges or piezoelectric elements to translate pressure into an electrical signal.

Applications for nyomatékmérs are extensive. In industrial settings, they are crucial for monitoring and controlling pressure in pipelines, boilers, tanks, and processing equipment, ensuring safety and efficiency. In automotive systems, they are used to check tire pressure and monitor engine oil pressure. In household appliances, they can be found in water heaters and HVAC systems. The selection of a specific type of nyomatékmér depends on factors such as the pressure range, required accuracy, operating temperature, and the properties of the fluid being measured.
