Precision pressure gauge accuracy measuring range and working principle
Precision pressure gauge accuracy: This instrument is a Bourdon tube pressure measuring instruments for measurements of high precision components, classification of a Bourdon tube type pressure gauge, is the high-precision standard Bourdon tube type pressure gauge. Precision grade consists of 0.4, 0.1, 0.25 and 0.16 level. 0.4 and 0.25 level instrument is often referred to as high-precision pressure gauges, precision of 0.1 and 0.16 meter is often referred to as high-precision precision pressure gauge/high precision pressure gauges. Precision pressure measuring range for the table category:
1. low pressure gauge (instrument measuring ceiling values of less than 0.1MPa instrument) 2. low pressure gauge (refer to instruments measuring ceiling values in 0.1MPa[including 0.1MPa] to 6MPa[including 6MPa] instrument) 3. a pressure gauge (refer to instruments measuring ceiling values in 10MPa[including 10MPa] to 60MPa[including 60MPa] instrument) 4. a pressure gauge (instrument measuring ceiling values greater than 60MPa 160MPa[including 160MPa] instrument) 5. pressure gauge (refer to instruments measuring ceiling values larger than 160MPa instrument) Precision pressure gauge according to the domain classification can be divided into:
1. vacuum gauge (refer to instrument field is negative pressure meter) 2. a pressure gauge (meter field at positive pressure gauges) 3. the pressure vacuum gauge (refer to instrument field is positive negative pressure to the pressure gauge) Precision pressure gauge according to the mounting structure can be divided into: 1. direct-mount (often called its base type instrument, both radial connector directly mounted) 2. cam mount (installed with a loop at the back or side of the instrument after) 3. built-in type (built-in type is divided into built-in type axial and radial built-in type, often called front side and front band edge instrument) The basic structure and working principle
Precision pressure gauge the basic structure is made of elastic sensing element, power-amplifier, digital apparatus and instrument enclosures and interfaces as shown in parts, and so on. Its working principle is: when the measured medium components through interfaces into the elastic sensing element (Bourdon), elastic sensing elements in measured media under the pressure of the free end will have the corresponding displacement of the corresponding displacement through a transmission amplifier and the device indicates the measured pressure of the medium. http://www.zhaohuisensor.com/
