Pressure Gauge Extensive Use
- Oct 16, 2017 -

Instrument for measuring fluid pressure. It is usually a comparison between measured pressure and a certain reference pressure, such as atmospheric pressure or other given pressure, and thus measured against pressure or pressure.

The precision digital pressure gauge has been accepted and accepted by lecturers because of its advantages such as easy operation, stable performance and easy reading. Ann, instrument and meter plant is one of the earliest development and production of digital pressure gauge enterprises, products of the first generation has developed from 1986 to now, the sixth generation, continuously improve product performance, variety, from single barometer to hydraulic table, active table, vacuum gauge, the company in the digital pressure gauge development and manufacturing has accumulated many successful experiences.

Precision digital pressure gauge is the crystallization of intelligent digital pressure meter. Instrument fully adopted the customers in the process of actual operation experience of advice, and reasonable and flexible use of microcomputer, integration, laser technology, to ensure the accuracy and long-term stability of the instrument. Can be used for lecturer room or online testing, calibration pressure transmitter, spring tube (precision) ordinary pressure gauge, pressure controller can pass pressure instruments, magnitude 0.05 is the best choice for customers ideal pressure standard instruments.

feature

The pressure gauge plays an important role in the formation test with its high precision, wide range, low maintenance cost and good vibration resistance. In particular, the pressure gauge is used as the preferred measuring instrument during the process of the test. At present, there are 2(X) one J pressure meters in every oilfield in our country, so it is still the main fault of the relief pressure meter

Instrument for measuring fluid pressure. It is usually a comparison between measured pressure and a certain reference pressure, such as atmospheric pressure or other given pressure, and thus measured against pressure or pressure. According to the principle of work, there are three types of fluid column, elastic and sensor. The liquid column type, such as u-tube pressure gauge and tube pressure gauge, is based on the hydrostatic principle to transform the pressure signal into a liquid column height signal. Water, alcohol or mercury are used as the test pressure. The elastic type, such as the packing tube pressure gauge, transforms the pressure signal into the mechanical deformation of the elastic element, which outputs the signal in a deflection way. Such pressure gauges are used in industrial systems. The principle of the pressure sensor is to convert the pressure signal into some kind of electrical signal, such as strain, which causes the resistance change through the deformation of the elastic element. Piezoelectric, piezoelectric effect, etc. The hydraulic pressure gauge is simple, sensitive and accurate. It is often used to calibrate other type pressure gauges. The disadvantages are large size, slow reaction and difficulty in automatic measurement. The elastic pressure gauge is easy to use and the range of pressure measurement is large, but the precision is low, and it can't be measured automatically. All kinds of pressure sensor to miniaturization, accurate and rapid measurement, especially to measure the dynamic pressure, for detecting multipoint circuit, signal conversion, long-distance transmission, connected to the computer, timely treatment, etc., and thus get rapid development and wide application.
