differenciálnyomásmérk

Differenciálnyomásmérő is a Hungarian term that translates to differential pressure gauge or differential pressure transmitter. It is a device used to measure the difference in pressure between two points in a system. This measurement is crucial for monitoring and controlling various industrial processes.

These instruments work by sensing the pressure at two separate locations and then calculating the difference between them. The output of a differential pressure gauge can be a direct reading on a dial or a transmitted electrical signal representing the pressure difference. Differential pressure transmitters are commonly used in applications such as flow measurement, where the pressure drop across an orifice plate or venturi tube is proportional to the flow rate. They are also used for level measurement in tanks, filter monitoring, and leak detection.

The design of a differential pressure gauge can vary, but many utilize a diaphragm that is subjected to the two pressures. The displacement or strain on the diaphragm, caused by the pressure difference, is then converted into a readable or transmittable signal. Factors like accuracy, range, and the environment in which it will be used influence the choice of a specific type of differential pressure gauge.
