The pressure sensors and transmitters are divided into gauge pressure , absolute pressure , differential pressure , and other species . 0.1,0.2,0.5,1.0 and other common precision. Measurable pressure range is very wide, small enough to tens of millimeters of water , up to hundreds MPa . Different types of pressure sensors and transmitters operating temperature range is also different , often divided into 0 to 70 ℃ , -25 to 85 ℃ , -40 to 125 ° C , -55 to 150 ° C on several levels , some special pressure sensors temperatures up to 400 to 500 ℃ .
The pressure sensors have different waterproof performance and explosion-proof rating based on different materials and structural design , wetted cavity fluid medium measurable due to differences in materials , shape , and often divided into dry gas , liquid acid corrosion solution, flammable gas liquids, pastes and special media . Pressure sensor and transmitter as an instrument need to be used in conjunction with the secondary instrument or computer, pressure sensors and transmitters of common power supply : DC 5V, 12V , 24V , ± 12V , the output are : 0 ~ 5V , 1 ~ 5V , the 0.5 ~~ 4.5V , 0 ~~ 10mA, 0 ~~ 20mA, 4 ~ 20mA , Rs232, Rs485 and computer interface .
The EPS-003 Series are mini pressure sensor , widely used in gas, liquid pressure testing, such as water , oil , mild corrosive liquids and gases .
The product's enclosure 1 C r 1 8 N i 9 T i stainless steel structure , pressure, core body selection of internationally renowned brands of ceramic capacitors cores , signal processing, digital V / I conversion circuit and the compensation of the whole temperature range .
