Product Description:

YJJ ARD20ZMPR Digital Compound Pressure Switch-100~100kPa 2-Channel PNP +4-20mA Analog Output

Features:

I. Model Explanation (ARD20ZMPR)
ARD20 = Full series of ARD20; Z: -100 to 100 kPa combined positive and negative pressure range, M- fixed KPa unit of pressure, P = 2-channel PNP switch output, R = 4-20mA analog current output attached
Compared with SMC-ZSE20 combined negative pressure pressure sensor, it is specifically designed for monitoring positive and negative air pressure.
II. Core Performance Parameters
Measurement range: -100 kPa to +100 kPa (combined pressure, capable of measuring negative pressure and positive pressure)
Sensing medium: Dry and non-corrosive gas (compressed air, nitrogen, etc.)
Measurement accuracy: ±2% FS (at 25°C room temperature)
Repeatability accuracy: ±0.2% FS
Temperature drift: ≤±3% FS in the environment of 0 - 50°C
Display: High-definition TFT color LCD screen, real-time pressure value
Pressure interface: Standard M5 internal thread / PT1/8 optional
III. Electrical Output Specifications
Power supply voltage: DC 12 - 24V ±10%
Maximum power consumption: ≤ 45mA (without external load)
Switch output: 2-channel PNP transistor output; maximum load of single channel 100mA, withstand voltage 30V
Analog output: 4-20mA current signal, connected to PLC for real-time pressure acquisition
Three trigger modes: simple switch mode, hysteresis difference mode, upper and lower limit window comparison mode
Output response delay: ≥ 2ms, hysteresis value can be freely set
IV. Environmental Hardware Parameters
Operating temperature: 0°C to +50°C
Storage temperature: -10 to 60°C
Protection grade: IP65
Resistant to vibration, industrial electromagnetic interference; supports pressure unit switching between kPa/MPa
