Description
The PASCO CI-6746 Economy Force Sensor is designed to be used with a PASCO
ScienceWorkshop Computer Interface. The sensor has strain gauges mounted
on a specially designed "S-bend beam". The beam has built-in over-limit protection
so it will not be damaged if a force greater than 50 newtons is applied.
Output voltage | + 8V for + 50 newtons (pushing) - 8V for - 50 newtons (pulling) |
---|---|
Output noise | ± 2 millivolts |
Force slew rate | 30 newtons / millisecond |
Bandwidth limit | 2 KHz (internal low pass filter) |
Output drive | 12 metres of cable without instability |
Beam deflection | 0.28 mm |

Connecting and Zeroing the Sensor
1. Connect the 8-pin DIN plug to an analog channel on the computer interface.
2. To "zero" the sensor, press and then release the tare button. When the tare
button is pressed, the voltage from the sensor will be set to approximately
zero volts.
Note: You can also zero the sensor while a force is applied to the sensor. For
example, if you want to measure the change in force during an
experiment, set up the experimental equipment as needed, and tare the sensor
at the beginning of the experiment before taking data. The sensor can maintain
its "zeroed" condition for more than thirty minutes.
