Gas Pressure sensor

The Gas Pressure sensor ML39m is designed to measure relative gas pressure in the range between -100 to 300 kPa (positive or negative differential changes in pressure). The pressure is measured via a pressure port located on the side of the sensor box. The end of the white pressure port has a small threaded end called a Luer-lock. With a gentle half turn, you may directly attach the plastic Luer-lock connector or the 20 mL plastic syringe (included with the sensor). The pressure sensor is a very precise piezoresistive pressure sensor. The Gas Pressure sensor is fairly durable, but it is designed only for use with non- corrosive, non-ionic working gasses such as air, dry gases and the like. It should not get wet. The sensor is delivered with the following accessories: a plastic 20-ml syringe with Luer-lock, a plastic Luer-lock connector, and aone plastic tube with an inside diameter of circa 6 mm.

This Gas Pressure sensor can be used in various experiments such as:
• Investigate the relationship between pressure and volume, Boyle’s law.
• Study the effect of temperature on gas pressure, Gay-Lussac’s law.
• Measure vapor pressure of liquids.
• Measurements of reaction rates as a gas is produced in a chemical reaction.

The Gas Pressure sensor ML39m is a digital sensor (on-sensor digital conversion), which gives calibrated values of the measured quantity. This sensor can only be connected to the CMA MoLab interface and not to other CMA interfaces such as VinciLab, CoachLab II+ or EuroLab.

Technical specifications of the sensor are described in its User's guide.
