Technical parameters Measuring range: -100Kpa ~ 200MPa; supply voltage: 12 ~ 35V DC (24V DC calibration voltage) / AC power supply output relay 220vAC capacity: 380V 3A, 220V 5A, 24V DC 5A equal precision: better than 0.0.5% FS , 1% FS and other settings range: full scale segment can set the sampling rate: 10 times / sec (speed can be customized according to customer requirements). Connection thread: M20 * 1.5, G1 / 4, G1 / 2,1 / 4NPT (can be customized according to customer needs) E-Another is more popular on the market in recent years is the electronic pressure switch for alternative electrical contacts pressure gauge and use in high demand on the industrial control systems. This pressure switch built-precision pressure sensor, precision instrumentation amplifier pressure signal MCU through high-speed data acquisition and processing, are generally used four LED digital display real-time pressure gas pressure switch, relay output, upper and lower control points set free, small hysteresis, anti-vibration pressure switches, fast response, reliable, high accuracy (accuracy typically ± 0.5% FS, high amounted to ± 0.2% FS), the use of hysteresis settings can effectively protect the pressure fluctuations Repeated high pressure switch operation, protection and control equipment, is to detect pressure, liquid level signal, pressure, liquid level monitoring and control of high-precision equipment. Features are: electronic display and intuitive elettrotec pressure switch, high precision, long life, through the display settings control point easy, but the relatively high price, you need to supply.
