  • High accuracy and repeatability
  • Linear pressure or air volume output
  • Both measurement and PID control output
  • One Modbus for monitoring or remote display
  • Alarm LED indicators and threshold limits
  • Auto Zero and overload protection is standard
  • Operator keyboard input for all functions
  • Modbus rtu, 0..10V and 4..20mA output
  • IP65 enclosure with easy mount wall brackets
  • 24 month warranty• 30 Years field application experience
The P-Sensor is a wall mount ultra low pressure transmitter which provides 0..10V and 4..20mA as well as Modbus communication over the selected range . The display can be adjusted via the keyboard to show the measured value in Pa, hPa, kPa, m/s, l/s, m3/s, m3/h and ACR (air change rate).A PID control output can be selected, but still having one output for monitoring the pressure or volume. The pressure ranges can be adjusted via the keyboard, but the base range is factory calibrated and certified i.e. 10, 25, 50, 100, 250 and going up to 7500 Pa. All ranges can be adjusted to +/- ie. -/+25Pa.Power supply 24Vdc/ac non-isolated or 24,110 and 230Vac isolated are available as standard.
