ALTA Industrial Differential Air Pressure

The ALTA industrial wireless differential pressure sensor measures the pressure difference between two input ports and transmits the measurement to iMonnit. When viewing the sensor from the top, the right inlet port is the negative or low side pressure input.

The ALTA wireless differential pressure sensor measures the pressure difference between two input ports and transmits the measurement to iMonnit.

  • Measurement range: -500 Pa to 500 Pa 
  • Calibrated and temperature compensated

The differential pressure sensor measures the pressure difference between two ports. When viewing the sensor from the top, the right inlet port is the positive or high side pressure input. When the pressure on this port is greater than the left port the sensor produces a negative pressure reading. When the pressure is greater on the left port the sensor produces a positive pressure reading.

Example Applications

  • Building/Room Pressure 
  • Air Flow 
  • Variable Air Volume Filter Status 
  • Duct Pressure 
  • Clean Rooms 
  • Hospitals 
  • Fume Hoods 
  • Computer Rooms 
  • Many additional applications

* Actual range may vary depending on environment.
** Battery life is determined by sensor reporting frequency and other variables. Other power options are also available.
