Overview

Pressure gauge specifications and selection are common measuring instruments widely used in various fields. It can intuitively display the pressure changes in each process link, insight into the conditions in the product or medium process, and form a monitoring of production operation. It first carries out safety movements in the process and constructs a fast and reliable safety guarantee through automatic interlocking or sensing equipment, playing an important role in preventing accidents and ensuring personal and property safety.

Product Details

Specification and selection of pressure gaugePrinciple: The pressure gauge displays pressure by the elastic deformation of sensitive components (Bourdon tube, bellows, bellows) inside the gauge, which is then transmitted to the pointer by the conversion mechanism of the movement inside the gauge, causing the pointer to rotate.

specification

From the perspective of installation structure types, there are upright and buried types. The upright type is the basic installation type, and is generally chosen when the installation structure type is not specified. The so-called buried pressure gauge is what we often refer to as a flanged pressure gauge.

kind

There are many types of pressure gauges, which are classified into general pointer type, electronic digital type, contact type, shock resistant type, and diaphragm type according to different installation and usage requirements. Pressure gauges are used for general air pressure and oil pressure.

A general pointer type pressure gauge, which simply displays the pressure magnitude without signal transmission or adjustment functions, is the most widely used type.

Digital contact electronic watch

The digital contact electronic meter has setting and control functions, and can automatically adjust parameters and upper and lower limits. It is a precision measurement and control instrument.

Legacy pressure gauge

Compared with general pressure gauges, legacy pressure gauges have an additional pointer that can stay at the maximum value, which can record the maximum value in the range for easy observation.

Seismic resistant pressure gauge

Diaphragm pressure gauges are suitable for measuring the pressure of media with acidity, alkalinity, high viscosity, easy crystallization, and solidification. It is necessary to avoid direct entry of the measuring medium into the pressure gauge, prevent sediment aggregation, and clean the environment easily.

Seismic resistant pressure gauge

Seismic pressure gauge, also known as anti-seismic pressure gauge, has good seismic resistance characteristics and is particularly suitable for use in situations of strong mechanical vibration or severe pulsation of medium pressure.
