'Product Details'

First, the product profile
High temperature pressure gauge for customers to measure high temperature pressure medium and manufacturing, is a diaphragm or diaphragm or spring tube for the measurement of pressure measurement devices, which is characterized by tolerance than the general high pressure gauge temperature, High-temperature pressure gauge manufacturing process compared to the general requirements of the pressure gauge technology is much higher, whether it is from the elastic sensing element material, or from the heat institutions, in order to ensure its high temperature characteristics, selection, manufacturing processes, testing Methods are very strict, it is different from other pressure gauges, self-contained.
High pressure type, the general micro-pressure type, low pressure type is more commonly used, high-temperature pressure gauge structure is mainly supported by the interface components, measuring agencies, transmission amplification (pressure, pressure, pressure, pressure, And an external heat dissipation device, wherein the interface supporting part of the high-temperature pressure gauge comprises an interface part with a connecting thread, an instrument case and a cover; the measuring device is a measuring element such as a diaphragm, a diaphragm or a spring tube, , Is the key high-temperature pressure gauges of the key components, because the high-temperature pressure gauge of the elastic components are closed, and to withstand the pressure and temperature test, high temperature pressure medium will cause harm to people, so the sealing and temperature Are generally required in the processing of elastic components, the components of the material itself and the solder has a more special requirements.Pressure element and the cooling device is measured in accordance with the medium temperature, acid and alkali characteristics and the pressure to bear to determine its Structure, style, material and other parameters, and its cooperation with a special calculation method is scientific rigor.
Prohibit the use of general pressure gauge high temperature measurement, because the high temperature pressure medium is dangerous, indiscriminate use of non-professional instrument may cause serious consequences

All parts of the high temperature gauges are made of stainless steel, the pressure system uses a special welding process. High temperature pressure gauge has excellent corrosion resistance, suitable for corrosive medium and tin brazing process. High temperature gauges have excellent high temperature corrosion resistance, suitable for corrosive medium and tin soldering process should not be used in high temperature medium or high temperature environment, pressure detection.Corrosion resistant high temperature pressure gauge is widely used in Petroleum, chemicals, pesticides, rubber, natural gas and other industrial enterprises.

Simple structure principle
The temperature of the pressure case, measuring system, indicating part of the radiator, elastic components. Elastic components using high temperature corrosion-resistant alloy materials and special welding process. Instrument under the action of the measured medium pressure spring tube end production of the corresponding displacement, And the indicating part is deflected by means of the pull rod and the gear turning mechanism, and the corresponding pressure value is indicated on the indexing disc.

Use and maintenance
1, Installation:
⑴ high temperature pressure gauge under normal circumstances must be installed vertically, if the angle problem should be made at the time of order.
(2) high temperature pressure gauge should be installed using a wrench to tighten, should not be strong twist the case before installation should check the installation interface thread specifications are matched, if different, you should use the variable diameter or transfer, forbidden to force into.
⑶ high-temperature pressure gauge with threaded sealing installation, please use the appropriate sealing material, or gasket, sealing material should be avoided too much to block the pressure medium into the mouth.
⑷ high-temperature pressure gauges sealed by the end of the installation should be noted that the seal or gasket has been placed in the sealed groove, the screw can not be too tight to squeeze deformation of the seal plugging the pressure medium into the mouth.
⑸ high temperature pressure gauge installation should be noted that the medium temperature, the use of the corresponding sealing material or a hard seal.
⑹ high pressure gauges should be installed in a good ventilation around the environment in order to facilitate cooling, installation space is not a good heat dissipation of the workplace should be installed ventilation team.
⑺ high temperature pressure gauge should be installed in the normal working conditions of vibration does not exceed the provisions of GB / T 4439 V.H.2 place.
⑻ high pressure gauges should be installed in a well-ventilated, no dust, dry workplace.
⑼ high temperature pressure gauge installation should be installed in the bottom of the instrument, the installation of high temperature valve in order to leak as soon as possible to close the line or instrument failure online replacement.
2, use:
⑴ high temperature pressure gauge should be noted that the maximum medium pressure can not exceed the full scale of the pressure gauge 1/2, accidental transient pressure can not exceed 2/3 of full scale.
⑵ high-temperature pressure gauges in the application, should always inspect the work of fine high-temperature pressure gauge state, if any abnormal inspection immediately, failure to immediately replace the replacement table
(3) high-temperature pressure gauge in the application, should be regularly checked, such as the article can be sent to use the quality of the Bureau of Quality Supervision, Inspection.
⑷ high temperature pointer pointer deflection should be smooth, the instrument in its measurement process, the pointer should not be beating or stagnation, such as the phenomenon should be immediately disabled for maintenance.
⑸ with zero-zero device high temperature pressure gauge, zero adjustment of the instrument should be in the elastic sensor without any additional load on the role of the state to adjust the zero.
⑹ high temperature pressure gauges filled with shock absorption buffer liquid, when the instrument is in normal working condition should be opened instrument oil hole at the explosion-proof hole, so that the pressure inside the shell and the atmosphere balance seal structure of high-temperature pressure gauge in different Area or different working environment temperature and pressure medium temperature, due to manufacturing and use of the atmospheric pressure difference and temperature difference, low-voltage instrument indication value does not return to zero or out of tolerance, please open the top of the instrument oil hole So that the instrument connected with the atmosphere inside.
3, maintenance
High-temperature pressure gauge, usually should pay attention to maintenance can be more effective long-term.
⑴ transport, high temperature pressure gauge should be possible to reduce the number of transit instrumentation transport, transportation, loading and unloading is prohibited in the handling of rough handling!
⑵ packaging, high temperature pressure gauge packaging should be consistent with national standard GB / T 15464 "instrumentation packaging general technical conditions" requirement, the type of protection from the factory set, please try to save the original packaging, to prepare for contingencies.
⑶ storage, high-temperature pressure gauge should be placed in the vertical do not use the measured media as far as possible after the use of the original packaging after packaging.
⑷ storage, high temperature pressure gauge should be stored in dry and ventilated room, indoor air should be clean and does not contain the composition of the corrosion of the composition of precision pressure gauges.
(5) enabled, a longer interval after the re-use of sealed high-temperature pressure gauge, the calibration test should be done and then put into use.
⑹ test, high-temperature pressure gauges should be regularly tested (at least once every six months).
