Wireless Differential Pressure and Differential Temperature Sensor – Differential by Wireless Connection


This very unique wireless sensor works by comparing the readings from one device node to another user-selected device node – then reporting the local pressure, local temperature – then differential pressure and temperature as compared to a user selected sensor.

For example, sensor A is located outside at ambient temperature and pressure.  Sensor B is located in a clean room under positive pressure and Sensor C is located in a different part of the cleanroom under a higher positive pressure.  Sensor B could be configured to report its pressure and temperature and the differential pressure between Sensor B and Sensor A.  (See the screen shot).  Sensor C could be configured to report its pressure and temperature and the differential pressure and temperature between sensor C and sensor B.

Sensor readings are reported in PSIA.

Leverage the Leap SensorManager software to send text, email, or telephone alerts when a pressure, temperature, or delta-pressure or delta-temperature threshold is exceeded.

Integrate the data from the differential pressure sensors into other software using our web-based API, Modbus, DNP3, or other data interface protocols.

The wireless sensor can be configured with pressure sensors that have different ranges, resolutions, and accuracies for different applications. See the specification below for more information on the different options.

Pressure sensors can be configured to specific applications.  The pressure and temperature sensors in the photos have the pressure and temperature sensor sealed inside the enclosure with a pressure port in the back of the enclosure.
