Student Workbook Physics Labs with Computers, Vol. 1012-07000A Tutorial Activities: Economy Force SensorThe Economy Force Sensor measuresforces between +50 and –50 newtons.The sensor output is +8 volts for aforce of +50 newtons and –8 volts fora force of –50 newtons. Pushing onthe sensor’s detachable hookproduces a positive voltage andpulling produces a negative voltage.Economy Force SensorThe sensor has an attached cable forconnecting to the interface. It also has a built-in over-limit protector in the case so the sensor willnot be damaged if a force above 50 newtons is applied. The housing has a thumbscrew formounting the sensor on a rod, and a long thumbscrew for mounting the sensor on a PASCO cartor onto the Accessory Bracket with Bumpers.The sensor has one built-in control.Tare Button: Use the tare button to zero the sensor before making measurements.To calibrate the sensor you will need an object of known mass, such as one kilogram.Set up the sensor with the interface• Plug the sensor cable into Analog Channel A on the interface.Set up the sensor in the software• In DataStudio, double-click the ‘ForceSensor” in the Sensors list in the ExperimentSetup window. Result: The sensor iconappears below Channel A of the interface.The sensor’s parameters (e.g., Force) appearin the Data list.• In ScienceWorkshop, click-and-drag the‘analog sensor plug’ icon to the Channel Aicon in the Experiment Setup window, selectthe name of the sensor from the list ofsensors and click ‘OK’ to return to theExperiment Setup window. Result: Thesensor’s icon appears below Channel A ofthe interface.500 scientificPASCOInterfacescientific300PASCOANALOG CHANNELSScience W orkshop DATA LOGGING INSTRUCTIONSScienceWorkshopInterface©1999 PASCO scientific A - 23
