High Resolution Force Sensor

PS-2189

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

Included Parts

1. High Resolution Force Sensor

2. Bumper attachment

3. Hook attachment

4. Cart/Bracket thumbscrew (M5 × 45 mm)

5. Rod clamp thumbscrew (1/4-20 × 0.75 inch)

Additional Part Required

• PASPORT interface or datalogger

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.

Connecting the Sensor to an Interface

1. Connect the sensor’s plug to any port of a PASPORT inter-

face 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.

3. Screw the hook attachment into the sensor.

4. Press or click the start button to begin recording data.

About the Force Measurement

Dynamic Over-sampling

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

force.

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

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.
