Sensors for National Instruments DAQ

Force Sensor

The FTN-5K utilizes load cell technology. A load cell is a force-sensing unit and is designed to measure a specific force ignoring other forces being applied. The FTN-5K operates in two selectable ranges, 0-5kg and 0-500 grams, and can be used in a range of applications to study topics such as harmonic motion, friction, centripetal force, etc.

Calibration Instructions
1. Install the IX-ELVIS board into the National Instrument ELVIS platform or the IX-myDAQ board onto the NI myDAQ. If using ELVIS, connect the ELVIS power supply to the ELVIS unit and connect it to the computer via a USB cable. Ensure both of the power switches are in the "on" position. For the myDAQ, connect it to the computer using the USB cable.

2. Connect the MINI DIN7 connector of the FTN-5k to either CH1 or CH2 of either the IX-ELVIS or IX-myDAQ board.

3. Open the recording software, select the channel that the FTN-5K is connected to and ensure the range is set to +/-5V.

4. Using the switch on the side of the transducer, select the force range you would like to use (500g or 5Kg).

5. Start with no load on the force transducer and press Set for SP2 Voltage which will 'tare' the device for no load.

6. Hang a known mass from the force transducer, enter the value of the mass in SP1Value and then press Set for SP1 Voltage.

7. If you change the force range you will need to recalibrate.

Measurement Instructions
1. Follow the calibration procedure outlined above.

2. Set up the desired experiment and press record.

*Note: The signal may be inverted when using the myDAQ setup.
