♦ Gas Pressure Sensor is used to measure the absolute pressure of air. It is connected to external air by hose placed at front side of the sensor. Pressure difference between tube and sealed vacuum cavity inside the sensor is formed. That pressure difference is converted to voltage signal. The output voltage is direct proportional to gas pressure.
♦ Operating temperature range: -40°C to 85°C.
♦ Storage temperature range: -55°C to125°C.
♦ Operating humidity range: 0 to 100%RH.
♦ Gas Pressure Sensor can only be used to measure: non-corrosive gas such as air and dry gas.
♦ The Gas Pressure Sensor can not be used to measure flammable gas.
♦ Gas Pressure Sensor can be used to measure pressure of steam. Please prevent liquid flowing into hose.
♦ For the pressure system, there is always air leakage in syringe. Therefore, if an experiment lasts for long time, the influence caused by air leaking will be greater. If possible, complete the test and experiment as soon as possible.
♦ Measure reaction rate of zinc and sulfuric acid
♦ Boyle’s law
♦ Charles’s law
♦ The relationship between liquid boiling point and pressure
♦ Measure chemical reaction rate
