MS31 Digital Pressure Switch with Display — NPN/PNP, 1-5V & 4-20mA Analog Output, Vacuum/Pressure, Emergency Protection

Compact MS31 electronic pressure gauge with digital readout, designed for vacuum and positive pressure monitoring. Switch outputs available as NPN and PNP; analog signals include voltage 1-5V and current 4-20mA. Two model ranges: MS31C for vacuum: -101.3-101.3KPa, and MS31P for pressure: -0.101-1.000MPa. Display covers the same ranges (MS31C: -101.3-101.3KPa; MS31P: -0.101-1.000MPa). Electrical requirements: Power Supply 12-24V DC+10% with a Current Consumption of 40mA. Mechanical durability: Withstanding pressure 500KPa (MS31C) / 1.5MPa (MS31P). Built-in emergency protection for safe operation.
