What types of pressure gauges are often used in hydraulic systems? According to what is classified? Dalan Motor tells you the specific classification as follows: 1. According to the measurement accuracy, it can be divided into precision pressure gauge and general pressure gauge. 1 The accuracy of the precision pressure gauge is 0.1, 0.16, 0.25, 0.4, and 0.5, respectively; 2 The measurement accuracy of the general pressure gauge is 1.0, 1.6, 2.5, and 4. 2, according to the benchmark of the indicated pressure can be divided into general pressure gauge, absolute pressure gauge, stainless steel pressure gauge and differential pressure gauge. 1 The general pressure gauge is based on atmospheric pressure; 2 The absolute pressure gauge is based on the absolute pressure zero; 3 The differential pressure gauge measures the difference between the two measured pressures. 3, according to the measurement range can be divided into vacuum gauge, pressure vacuum gauge, micro pressure gauge, low pressure gauge, medium pressure gauge and high pressure gauge. 1 vacuum gauge is used to measure the pressure value less than atmospheric pressure; 2 pressure vacuum gauge is used to measure the pressure value less than and greater than atmospheric pressure; 3 micro pressure gauge is used to measure the pressure value less than 60000 Pa; 4 low pressure gauge is used to measure 0 ~6MPa pressure value; 5 medium pressure gauge is used to measure the pressure value of 10~60MPa; 4. According to the display mode, it can be divided into pointer pressure gauge and digital pressure gauge. 5, according to the use of different functions can be divided into local indicating pressure gauge and charged signal control type pressure gauge. 1 General pressure gauges, vacuum pressure gauges, shock-resistant pressure gauges, stainless steel pressure gauges, etc. all belong to the local indication type pressure gauge, and there is no other control function except the indicated pressure. 2 Charge signal control type pressure gauge output signals mainly include: a, switch signal (such as electric contact pressure gauge) b, resistance signal (such as resistance remote pressure gauge) c, current signal (such as inductive pressure transmitter, remote pressure Table, pressure transmitter, etc.) 6, according to the characteristics of the measured medium can be divided into: general pressure gauge, corrosion-resistant pressure gauge, explosion-proof pressure gauge and special pressure gauge. 1 General type pressure gauge is used to measure the pressure of liquid, gas or steam which has no corrosive effect on copper and copper alloy without explosion, non-crystallization and non-coagulation; 2 corrosion-resistant pressure gauge is used to measure the pressure of corrosive medium, commonly used There are stainless steel pressure gauges, diaphragm pressure gauges, etc.; 3 explosion-proof pressure gauges are used in hazardous locations where there is an explosive mixture in the environment, such as explosion-proof electrical contact pressure gauges, explosion-proof transmitters, etc. 7, according to the use can be divided into ordinary pressure gauge, ammonia pressure gauge, oxygen pressure gauge, electric contact pressure gauge, remote pressure gauge, vibration pressure gauge, pressure gauge with inspection pointer, double needle double tube or double needle single tube pressure gauge , digital pressure gauges, digital precision pressure gauges, etc. ----- Responsible Editor: Dalan Oil Pump Motor 02- Purchasing Consultant Copyright http:/(Dalan Motor) Reprint, please indicate the source http://news.chinawj.com.cn Aluminum Furnitures,Aluminium Furniture Cabinets,Aluminium Folding Container House,Aluminum Awning Window Hardware Guangdong Jihua Aluminium Co., LTD , https://www.gdaaluminiumprofile.com
