The PS-2114 Relative Pressure Sensor measures small changes in pressure
(in kilopascals).

Additional Equipment Needed

• PASPORT

• EZscreen or DataStudio

™ interface (USB Link, Xplorer, etc.)

software (version 1.5 or later)

Equipment Setup

1. Connect the PASPORT interface to a USB port on your computer or to a USB hub.

2. Connect the sensor to a PASPORT interface.

3. The softw a re laun c hes when it detec t s a PASP ORT sensor. From the

Pressure vs. Temperature inside an Glass Air Chamber
Alternately Dipped in Cups of Hot and Cold Water

DataStudio Task: Procedure:

Create a graph of pressure
vs. temperature:

Change the measurement
unit:

Change the sample rate:

From the Data list, use your mouse to drag the Pressure
icon over the y-axis. Drag the Temperature icon over the
x-axis and release the mouse.

Click the Setup button to open the Experiment Setup
window. Click on the Maximize button and scroll to the
Relative Pressure Sensor box. Next to the sensor box,
click the down arrow to select a different measurement
unit.

In the Experiment Setup window, scroll to the Relative
Pressure Sensor box. Click on the Plus button to
increase the sample rate or the Minus button to decrease
the sample rate.

CARD 1B

DataStudio Acti vity: Pressure vs.
Temperature

Equipment required: Relative Pressure Sensor (PS-2114), Fast Response
Temperature Sensor (PS-2135, 3-pack), cup of hot water, cup of ice cold
water, glass test tube and rubber stopper (with two holes), wax paper

1. Plug the Pressure Sensor and Fast Response Temperature each into a
PASPORT interface (connect ed to a USB-comp at ib le compu te r).

2. Plug a c onnecto r to the end of the Relative Pressure Sensor.

3. Place the two-holed stopper into the glass tube (to create an air chamber).

4. Slide the probe of the Fast Response Temperature Sensor through one of
the holes in the stopper. Wrap a piece of wax paper around the stopper
hole to ensure a tight seal, such that air does not leak out.

5. Plug a plastic valve into the other hole in the stopper. Attach a piece of
plastic tubing from the connector on the Pressure Sensor to valve in the air
chamber.

6. In DataStudio software, open a Graph display and click the Start button.
Alternate placing the air chamber in the cups of cold and hot water.

Other Suggested Activities

• EZscreen activity: With your hands (or a halogen lamp) as a heat source,
measure the pressure inside the glass tube as you alternate doing the
following: a) use your hands or the lamp to heat the outside of the glass
tube and b) remove the heat source from the outside of the glass tube.

• DataStudio activity: Use the Relative Pressure Sensor with the Heat
Engine Apparatus (TD-8572 or TD-8592) to study Boyle’s law, the Carnot
cycle, or another activity described in the Heat Engine Manual.
