Description

Used to monitor pressure changes in a gas. The range is wide enough to perform Boyle’s law yet it is sensitive enough to conduct vapor-pressure or pressure-temperature experiments. Biology teachers can use the Gas Pressure Sensor to monitor transpiration or respiration in an enclosed environment.

Assembly Instructions

N/A

Precautions

The Gas Pressure Sensor sensing element will be damaged with direct contact to liquid.

Specifications
• Pressure Range: 0 to 210 kPa (0 to 2.1 atm or 0 to 1600 mm Hg)
• Accuracy: ±4 kPa
• Maximum pressure that the sensor can tolerate without permanent damage: 4 atm
• Sensing Element: Honeywell SSCMRNN030PAAA5

Note: There are two variants of the Gas Pressure Sensor.

Version 1.3 of the sketch for TI-Innovator™ Hub includes the calibration constants for one of the two variants.

The reference programs show how to use the CALIBRATE command to use the other type of Gas Pressure sensor.
