Relative Pressure Sensor is used to measure relative pressure. There is a layer of film designed in the sensor which bends according to the pressure. Both ends of the film are connected to input tubes. When there is a pressure change occur between two inputs, the pressure applied on both ends of film will change. The output voltage of sensor is direct proportional to two relative pressure change.

Typical experiment
Boyle's law
- Charles's law
- Explore internal pressure of liquid
- Explore relationship between boiling point and pressure of liquid.
- Explore transpiration of plants.
Note
- Operating temperature range: -40°C~85°C.
- Preserve temperature range: -55°C~125°C.
- Operating humidity range: 0~100%RH.
- Relative Pressure Sensor can only be used to measure: non-corrosive gas such as air and dry gas.
- Relative Pressure Sensor is not suitable for measuring flammable gas.
- Relative Pressure Sensor can be used to measure pressure of steam. Please prevent liquid flowing into tube.
- In the pressure system, gas in container always leaks. Longer research will cause more affection by gas leaking. Please complete the experiment as soon as possible.
