Brief description of the pressure gauge
2011-9-14 15:19:21

压力表 可以 分为 指针压力 表和 数显压力表 其中指针压力表是靠弹性元件和很高的机械强度来工作的 数显压力表 是靠传感器受压来工作的 Pressure gauges are commonly used equipment in industrial control and measurement processes . Pressure gauges can be divided into pointer pressure gauges and digital pressure gauges . Among them, pointer pressure gauges work by elastic components and high mechanical strength. The watch works by pressure on the sensor . 越来越 受使用者的青睐, 在工业生产环节使用 比较 广泛 With the development of industry, digital pressure gauges are more and more popular with users, and they are widely used in industrial production .
     指针压力表 的工作原理是通过内部的弹性敏感元件在压力 作用 发生弹性变形来指示压力数值 指针压力表一般都使用弹簧管 膜片 膜盒 及波纹管作为弹性元件 这些弹性元件在发生形变后会通过齿轮传动机构将变形放大 从而显示出相应的压力值 1. The working principle of the pointer pressure gauge is to indicate the value of the pressure through the elastic deformation of the internal elastic sensor under pressure . The pointer pressure gauge generally uses spring tubes , diaphragms , diaphragms and bellows as elastic components . After deformation of these elastic elements, the deformation is amplified by the gear transmission mechanism , thereby displaying the corresponding pressure value .
    2   的工作原理是压力通过压力传感器 由压力传感器传输给芯片再通过显示屏将压力值显示出来 的, 数显压力表一般分为 普通数显压力表 精密数显压力表 防爆数显压力表 The working principle of the digital pressure gauge is that the pressure is transmitted through the pressure sensor , transmitted by the pressure sensor to the chip, and then the pressure value is displayed on the display screen . The digital pressure gauge is generally divided into : ordinary digital pressure gauge , precision digital pressure gauge , Explosion-proof digital pressure gauge .
     也就是以在气压力作为相对点来进行测量 The pressure measured by the pressure gauge is generally relative pressure , that is, the pressure is measured as the relative point to measure . The final result displayed by the pressure gauge is also the pressure presented by the measured object under atmospheric pressure .

误差大 ,而 数显压力表精度高 直观 方便读数 The pointer pressure gauge has low accuracy and large error , while the digital pressure gauge has high accuracy , intuitive and convenient reading .
