Efento Differential Pressure Logger NB-IoT Sensor

Wireless differential pressure loggers are used to measure the pressure difference between two rooms. Discover more with the Efento NB-IoT differential pressure logger.


The Efento Differential Pressure Logger NB-IoT sensor is equipped with two tubes, enabling you to monitor the differential pressure difference between two rooms.

Designed to revolutionise your remote monitoring and data acquisition needs, this sensor delivers the data you require with precision, reliability, and seamless connectivity.

Ideal to enable you to remotely monitor temperature in areas which require constant supervision. Example applications could include:

  • Manufacturing facilities
  • Hospitals
  • Clean rooms
  •   many more!

Recorded data will be transmitted from the sensor by the connected NB-IoT network which is fulfilled by inserting a compatible SIM card. This data can then be decoded by our IoT middleware platform, Symbius.
