SMC PSH Condensation Checker (Digital Temperature/Humidity Switch)

SMC PSH Condensation Checker (Digital Temperature/Humidity Switch)

SMC PSH series 3-screen digital temperature/humidity switch that monitors relative humidity and temperature of compressed air in real time to prevent condensation trouble.

Key features

  • Displays relative humidity (atmospheric or under pressure) and temperature on a 3-screen display
  • Two switch outputs (NPN/PNP selectable) with IO-Link or 1-5 V analog output
  • Detects dryer failure or loss of dehumidifying capacity before water reaches valves and actuators
  • R1/8 piping; consumes approx. 5 L/min at 1 MPa
  • Options: connector lead wires W/V/R (ZS-46-5F series), bracket A (ZS-55-A), panel mount B/D (ZS-55-B/D); sintered element EBD-3.8-3-2
