About the difference between digital pressure gauge and ordinary pressure gauge

Digital pressure gauges are widely used for measuring the pressure of medium, gas, steam and other medium without gas, liquid pipes and containers for measuring the risk of no explosion, no crystals, no solidification, and no corrosion to the alloy. It has the advantages of small size, safe and reliable performance, and clear display. Can accurately measure flow, liquid level, gauge pressure, absolute pressure, vacuum degree and specific gravity. It is directly connected with the secondary instrument and the computer control system to realize the automatic detection and control of the production process. Can be widely used in various industrial fields of gas, liquid pressure detection digital pressure gauge principle: digital pressure gauge through the table of sensitive components (Boden tube, bellows, bellows) elastic deformation, liquid level transmission Device, input type liquid level transmitter, static pressure level transmitter, and the pressure transformation is transmitted to the pointer by the conversion mechanism of the movement in the digital pressure gauge, causing the pointer to rotate to display the function of the pressure digital pressure gauge. : Provides high resolution and accuracy in the low pressure range when needed Stability mode: The stabilization function is used to stabilize readings. It will display the average of the first four readings. Auto-shutdown: Auto-shutdown after 40 minutes Save battery Zero-return function: Provides quick one-button zero return Digital pressure gauge pressure representation There are two ways to express pressure: One is The pressure represented by the absolute vacuum as the reference is called absolute pressure; the other is the pressure expressed by the atmospheric pressure as the reference, Jiangsu Hengtai Instrument Co., Ltd. Com is called relative pressure. Since most pressure gauges measure the relative pressure, the relative pressure is also called gauge pressure. When the absolute pressure is less than the atmospheric pressure, the absolute pressure in the container may be expressed as a value less than one atmosphere. Our statutory pressure unit is Pa(N/m2), which is called Pascal, or Pa. Because this unit is too small, it often uses its 106 times unit MPa (megapascals).
