Pressure Measuring Instruments

Micro manometer u tube with enlarged ends.

Pressure measuring instruments. National instruments offers a wide variety of pressure measurement solutions ranging from simple secure wi fi devices to high channel rack mountable systems. The barometer is a device meant for measuring the local atmospheric pressure. Gauge pressure absolute pressure differential pressure flow and level. Within pressure measuring instruments there are thousands and thousands of options and varieties on the method and connection of pressure measuring many industries facing the challenge of excellent and reliable pressure measurements.

The diaphragm pressure gauge 6. Manual sphygmomanometers are used with a stethoscope when using the auscultatory technique. And the devices are. Electronic assemblies or components are integrated into a mechanical pressure measuring instruments the measured pressure is displayed locally however in addition the pressure measuring instrument offers an electrical signal or includes an electrical switching function.

You can integrate all ni pressure measurement systems with other measurements and sensor types because of the modular design. Differential where the sensor has two ports for the measurement of two. There are 4 main types of pressure measurement. Digital pressure transmitter for gauge and differential pressure with an increased measuring accuracy of 0 04.

Pressure measurement devices such as inclined manometer bourdon gauge diaphragm gauge bellows pressure transducers and electronic pressure sensors are used to measure extreme pressures with high accuracy. Types of pressure measurement with pressure application examples. The indication of the pressure is made by a pointer on a dial with a standardised scale range over 270 angular degrees. The bourdon gauge 5.

Pressure is typically measured in units of force per unit of surface area many techniques have been developed for the measurement of pressure and vacuum instruments used to measure and display pressure in an integral unit are called pressure meters or pressure gauges or vacuum gauges. Sealed referenced to a sealed chamber closed with atmospheric pressure approximately 1bar. Sitrans p ds iii the tried and tested sitrans p ds iii portfolio offers the right solution for every measurement task. The barometer 2 piezometer or pressure tube 3.

A sphygmomanometer also known as a blood pressure monitor or blood pressure gauge is a device used to measure blood pressure composed of an inflatable cuff to collapse and then release the artery under the cuff in a controlled manner and a mercury or aneroid manometer to measure the pressure. Absolute the reference is a vacuum 0bar or no pressure. For pressure measurement in hydraulics analysis in civil engineering the knowledge of construction and working of these devices is a must. Gauge reference to atmospheric pressure.

If the pressure measuring device is in addition filled with a liquid then the measuring instrument is optimally protected by damping against destruction from high dynamic pressure loads or vibrations. List of pressure measuring devices.
