Description

The PS-LS-D sensors are powered by solar power + li-on battery with a Differential Pressure Type sensor which can measure Air, Water pressure, and liquid level and upload the sensor data via wireless to the LoRaWAN IoT server.

Sometimes it is unnecessary to monitor the absolute air pressure but we need to know the difference in pressures in different points. One example may be before and after a valve in a pipe. If the valve is fully open, the pressure on both sides should be the same. If there's a difference in the pressure, it could be the valve isn't fully open or there's a blockage.

Differential Pressure Sensor has two air pressure inputs. It monitors the pressure difference between these two inputs and puts the value.

Differential Pressure Sensors can be used in home and industrial environments for applications such as offshore and subsea gas processing, and remote heating systems.
