PASCO Interface

PASCO Data Acquisition Software

*See the PASCO catalog or the PASCO web site at www.pasco.com for more information.

The sensor is designed to work with a PASPORT-compatible interface (such as the UI-5100 850 Universal Interface) and

PASCO data acquisition software (such as PASCO Capstone). With the data acquisition software, the sensor can be used to measure change in pressure over a period of time.

The sensor includes plastic tubing, four inline connectors, and four quick connectors. The quick connector attaches to the pressure port on the front end of the sensor. The inline connector can be used to attach a piece of tubing to a one-hole stopper, for example.

Setup the Relative Pressure Sensor

• Plug the Relative Pressure Sensor into one of the

PASPORT input ports of a PASCO interface.

Introduction

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

Sensor

NOTE: If more distance is needed between the sensor and the interface, plug the sensor into a PASPORT Extension

Cable, and then plug the cable into the interface.

R e l a t i v e P r e s s u r e S e n s o r S u g g e s t e d A c t i v i t i e s

• Start the PASCO data acquisition software. Set up a data display in the software.

Using the PASCO Capstone Software

• Click the “Hardware Setup” icon in the Tools palette to open the “Hardware Setup” panel. Confirm that the Relative Pressure Sensor icon appears with the interface’s icon.

• Click the “Data Summary” icon in the Tools palette to open the “Data Summary” panel. The panel lists the sensor’s measurements.

• Click one of the display templates in the workbook page, or double-click an icon in the “Displays” palette to open a data display.

Using the SPARK Science Learning System

• Start the interface and plug the sensor into a port on the

SPARK SLS.

• In the sensor parameter screen, tap ‘Relative Pressure’ to highlight it, and then tap ‘Show’ to open a graph display.

Record Data

• Click “Record” or tap the ‘Start’ button to begin recording data.

Suggested Activities

Measure Pressure versus Temperature

Use the Relative Pressure Sensor with a PASCO temperature sensor to measure the change in pressure inside a chamber as the chamber is warmed or cooled to different temperatures.

Measure Pressure versus Volume

Use the sensor with a PASCO Heat Engine/Gas Law Apparatus (such as the TD-8572 or TD-8592) to study the relationship of pressure and volume (Boyle’s Law).

Respiration Rate

Use the sensor with the PASCO Respiration Belt (CI-9842) to study breath rate.
