Dickson Touch Screen Data Logger TWP were made to simplify, yet enhance your monitoring experience. With a Dickson touchscreen TWP, you can view temperature, humidity or differential pressure data with nothing more than the touch of a finger. With access to your data right on the screen, proving historical monitoring during an audit has ever been easier.
Long Range Wireless Differential Pressure Sensor
:
Monnit 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
Principle of OperationMonnit 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 positive pressure reading. When the pressure is greater on the left port the sensor produces a negative pressure reading.Example Interfacing
