Introduction

The High Resolution Force Sensor connects to a PASPORT interface or datalogger and records force in the range of

−50 N to

+50 N at a rate of up to 1000 samples per second. High resolution, dynamic over-sampling, and a low drift rate make the sensor well suited for measuring very small changes

Set-up

Connecting the Sensor to an Interface

1.

Connect the sensor’s plug to any port of a PASPORT interface or datalogger.

2.

If you are using a computer, connect the PASPORT interface to it and start DataStudio.

Zeroing the Sensor

Press the ZERO button on the sensor. The sensor’s output is adjusted to read zero.

Connecting Bumper and Hook Attachments

Screw the bumper or hook into the sensor as illustrated.

Quick Start

1.

Connect the High Resolution Force Sensor to your

PASPORT interface.

2.

If you are using a computer, connect the PASPORT interface to it and start DataStudio.

3.

Screw the hook attachment into the sensor.

4.

Press or click the start button to begin recording data.

5.

Push or pull the hook. The sensor measures the applied force.

About the Force Measurement

Dynamic Over-sampling

To increase the degree of dynamic over-sampling, lower the sample rate.

Over-sampling reduces noise, produces smoother data, and improves the measurement resolution. This effect is especially noticeable when very small force changes are measured. The

H i g h R e s o l u t i o n F o r c e S e n s o r PS- 2 1 8 9 degree of over-sampling depends on the sample rate. Maximum over-sampling occurs at sample rates of 20 Hz and slower.

Sample Rate

By default, the sensor collects 10 samples per second. It can collect data as fast as 1000 samples per second and as slow as one sample every four hours. Change the sample rate in DataStudio or on your datalogger.

Inverted Output

By default, the sensor registers pushing as a positive force and pulling as a negative force. To register pulling as positive and pushing as negative, select the Force (Inverted) measurement in

DataStudio or on your datalogger.

Sensor Mounting

Mounting the Sensor on a Rod

Slide the sensor onto a rod and secure it with the thumbscrew as illustrated.
