Stainless steel shock resistant pressure gauge

Stainless steel shock resistant pressure gauge

principle

The shock resistant pressure gauge consists of a pressure guiding system (including joints, spring tubes, flow limiting screws, etc.), a gear transmission mechanism, a reading device (pointer and dial), and a housing (including case, cover, glass, etc.). The shell of the shock resistant pressure gauge is an airtight structure, filled with damping fluid (usually silicone oil or glycerin) inside the shell, which can resist working environment vibration and reduce the pulsation effect of medium pressure

characteristic

The shock resistant pressure gauge relies on measures such as internal filling with damping oil and supporting buffering devices, and has good shock resistance performance. Suitable for situations where the pressure of the tested medium undergoes strong pulse changes or pressure shocks, and where there is frequent sudden unloading in the production process, as well as places with large environmental vibrations. The instrument can measure the average pulsating pressure of gases and liquids, overcoming the damage caused by strong medium pulses and environmental vibrations to the instrument and ensuring the accuracy of readings.

classification

Seismic pressure gauges can be divided into precision pressure gauges and general pressure gauges based on their measurement accuracy. The measurement accuracy levels of precision pressure gauges are 0.1, 0.16, 0.25, 0.4, and 0.05, respectively; The measurement accuracy levels of general pressure gauges are 1.0, 1.6, 2.5, and 4, respectively Level 0.

Seismic pressure gauges are divided into general pressure gauges, absolute pressure gauges, stainless steel pressure gauges, and differential pressure gauges according to their measurement standards. Generally, pressure gauges are based on atmospheric pressure; The absolute pressure gauge is based on the absolute pressure zero position; The differential pressure gauge measures the difference between two measured pressures.

Seismic pressure gauges are divided into vacuum gauges, pressure vacuum gauges, micro pressure gauges, low pressure gauges, medium pressure gauges, and high pressure gauges according to their measurement range. A vacuum gauge is used to measure pressure values below atmospheric pressure; A pressure vacuum gauge is used to measure pressure values below and above atmospheric pressure; Micro pressure gauges are used to measure pressure values below 60000 Pa; Low pressure gauge is used to measure pressure values from 0 to 6MPa; The medium pressure gauge is used to measure pressure values between 10 and 60 MPa; High pressure gauges are used to measure pressure values above 100MPa.

Seismic pressure gauges are divided into pointer pressure gauges and digital pressure gauges according to their display methods.

Seismic pressure gauges can be classified according to their usage functions: pressure gauges can be divided into on-site indication pressure gauges and live signal control pressure gauges according to their usage functions.

General pressure gauges, vacuum pressure gauges, shock resistant pressure gauges, stainless steel pressure gauges, etc. are all local indication type pressure gauges, which have no other control functions except for indicating pressure.

The output signals of the electrified signal controlled pressure gauge mainly include:

1. Switch signal (such as electric contact pressure gauge)

2. Resistance signal (such as resistance remote pressure gauge)

3. Current signals (such as inductive pressure transmitters, remote pressure gauges, pressure transmitters, etc.)
