Digital Pressure Gauge More And More Extensive
- Oct 10, 2017 -

In the process of industrial process control and technical measurement, Digital Pressure Gauge mechanical pressure gauge has been widely used because of its high mechanical strength and convenient production.

Elastic-sensitive elements in mechanical pressure gauges produce elastic deformations as the pressure changes. Mechanical pressure gauges using spring tube (Bourdon tube), Digital Pressure Gauge diaphragm, membrane box and bellows and other sensitive components and according to the classification. The measured pressure is generally regarded as relative pressure. General relative point is chosen as atmospheric pressure. The elastic deformation of the elastic element under the action of the dielectric pressure, which is amplified by the gear drive mechanism of the pressure gauge, shows the relative value (or high or low) relative to the atmospheric pressure. 1. Digital Pressure Gauge The requirements for measurement in process production process, including range and accuracy. In the case of static test (or slow change), the maximum value of the pressure gauge is chosen to be two-thirds of the full scale of the pressure, and the maximum value of the measured pressure in the case of fluctuating pressure is selected by One-second of the scale value of the pressure gauge.

The accuracy level of common pressure measuring instruments is 0. Level 4, 1. Level 0, 1. Level 5 and 2. 5-Level 4-level, from the production process accuracy requirements and the most economical angle selection. The maximum allowable error of the instrument is the product of the range of the meter and the degree of accuracy, and if the error value exceeds the accuracy of the process, Digital Pressure Gauge the pressure meter with a higher accuracy must be replaced.

2. The properties of the measured medium, such as state (gas, liquid), temperature, viscosity, corrosivity, degree of contamination, flammable and explosive degree, etc. Digital Pressure Gauge such as oxygen table, acetylene table, with "Forbidden oil" sign, specially used for special medium corrosion-resistant pressure gauges, high temperature pressure gauges, diaphragm pressure gauges.

3. On-site environmental conditions, such as ambient temperature, Digital Pressure Gauge corrosion, vibration, moisture level. such as shockproof pressure gauges used for vibration environmental conditions.

4. Suitable for staff observation. According to the position and illumination of the instrument, the meter with different diameter (dimensions) is selected.

The horizontal section of the connecting catheter should have a certain inclination to facilitate the removal of condensed liquids or gases. When the measured medium is a gas, Digital Pressure Gauge the catheter should be inclined toward the pressure inlet, and when the medium is measured, the catheter should tilt to the direction of the measuring instrument, and the tilt can be slightly larger when the measured parameter is a smaller differential pressure value. In addition, if the catheter is in the upper and lower corners, Digital Pressure Gauge the discharge condensation liquid device or the discharge device shall be placed at the lowest point in accordance with the medium of the catheter to ensure that the accuracy of the measurement is not affected by the accumulation of condensation liquids or gases in the catheter for a considerable period of time.
