Monnit Alta Wireless Differential Air Pressure Sensors

The Monnit ALTA 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. 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. Measurement range is -500 Pa to 500 Pa and the sensor is calibrated and temperature compensated.

The general purpose AA model should only be operated in dry, low humidity environments. Should you need a sensor that operates at extreme temperatures and can withstand getting wet or condensed on, please consider the IP65 NEMA 4X model.

Important Note: Monnit Alta wireless sensors must be paired with a Monnit Alta gateway in order to have a working system. One Serial Modbus gateway can support up to 50 sensors and one Ethernet, USB, or Cellular gateway can support up to 100 sensors. Monnit Alta gateways can be found on the accessory tab.
