Vacuum pressure gauge characteristics and applications

Vacuum pressure gauge is by measuring system ( Including joint, spring pipe, gear transmission mechanism) And instructions ( Include Pointers, dial) , watch case parts. The working principle is based on the deformation of elastic element spring tube. When the measured medium is produced by the joint into the spring tube with side displacement, the displacement with the aid of connecting rod by gear transmission mechanism of pressure transmission and amplification, the pointer indicates that the pressure on the dial. Vacuum pressure gauge use note: 1, the instrument must be vertical: 17 mm wrench to tighten, should be used when installation should not strong torsional case; Transportation should avoid collision; 2, instrument using appropriate for - in ambient temperature 25~55℃； 3, using work environment vibration frequency & lt; 25 hz, the amplitude is not greater than 1 mm; 4, used by environmental temperature, indicating value of the instrument is not back to zero or appear, indicating error can cut open upper case sealing rubber plug, make the instrument lumen and atmosphere are interlinked; 5, instrument using range, should be between 1/3 to 2/3 of the ceiling; 6, in the measurement of corrosive medium, may the crystallization medium, the viscosity larger medium should add isolation device; 7, instrument should be regular checks, if discover fault shall promptly repair; The characteristics of the vacuum pressure gauge: ( 1) Stable performance, high measurement precision, response speed faster. ( 2) Is the total pressure measurement, including gas and steam pressure. ( 3) The results of the measurement has nothing to do with the gas species, composition and properties. ( 4) Vacuum gauge inside without high temperature parts, won't make the oil vapor. ( 5) If choose corrosion resistant materials, can measure the corrosive gas pressure. ( 6) Firm structure, and sealing and makes the pipes easier to install. ( 7) Easy operation, do not need to adjust, but need to check on a regular basis. Vacuum pressure gauge is based on the atmospheric pressure as a benchmark to measure instrument is less than the atmospheric pressure. Used to measure for steel, copper and copper alloy non-corrosive effect, no explosion danger of crystallize, solidify liquid, gas, negative pressure. Widely used in petroleum, chemical, metallurgical and other industrial process vacuum measurement.
