Installation method: radial Joint screws: g1/2 or 1/2pt (threaded can be customized) (2) product description Digital display electric contact pressure gauge Also known as digital pressure controller or pressure relay, it can set and control function, upper and lower interval can be set within the small spacing, alarm can be set time delay, is the first choice for precision measuring control instrument, can complement the traditional mechanical electric contact pressure gauge in measurement accuracy and control the lack of sensitivity and service life. PIONEER digital display electric contact pressure gauge imported high quality pressure sensor chip, high precision and high stability performance to meet the different needs of customers. The temperature of the instrument through strict precision and linear compensation, adopting modular CPU signal processing, the standard of 4 ~ 20 ma output signals, and set control, the control points can be set freely, which can realize the medium pressure testing, display and output, alarm, the purpose of the control and data transmission, can replace ordinary pressure transmitter and traditional mechanical electric contact pressure gauge. Digital display electric contact pressure gauge is widely used in petroleum, chemical, electric power, environmental protection, automatic water supply, the village in the secondary water supply in areas such as the table of various gas, liquid pressure, absolute pressure measuring control, can also be used for sealing leak detection equipment, is the ideal of industrialization at the scene of intelligent measurement and control instrument. (iii) product features: 1. Four leds display, the reading is intuitive and clear. 2. Have the upper and lower limit setting and control function. Set the action points at any point in the full range of the meter, and set the upper and lower action points to a small distance. 3, good stability, temperature drift stability of 0.005 FS / ℃ (%) or less (0.2% FS/year) 4. Anti-emi design, suitable for harsh environment. 5, 4~20mA analogue signal, suitable for distant transmission. 6. The control points can be set arbitrarily, the panel is set to convenient operation, and the menu setting is simple and easy to use. 7. High precision: less than 0.1%FS (analog signal)/less than 0.5 (digital signal). 8. Optional rs232/485 communication interface. 9. High anticorrosion, application of SUS316L or ceramic diaphragm for wider range of application. 10. Pressure overload limiting signal processing. 11, benan explosion-proof.
