PASPORT Displacement Sensor Introduction
2
Introduction
The PASPORT Displacement Sensor works with a Digital Indicator to measure dis-
placements to within 0.01 millimeters or 0.5 mils (thousandths of an inch) over a
range of 10.00 millimeters (0.3937 inches or 393.7 mils). The Displacement Sensor
comes with a Digital Indicator, a Pivot Rod Clamp for mounting the indicator on a
support rod (not included), and a screwdriver for removing or replacing the back
panel of the indicator.
The sensor cable from the Displacement Sensor connects to a small data port on the
left side of the indicator. The Displacement Sensor can be connected to any
PASPORT interface.
The Displacement Sensor is ideally suited to measure the small deflections of mem-
bers of a structure built using one of PASCO’s Structure Sets. For example, the sensor
can dynamically measure the deflection of the road bed of a bridge when a load is
applied to the structure.
Assembly
The Digital Indicator can be mounted on a support rod up to 12 mm in diameter. To
mount the indicator on a support rod, first replace the flat back panel of the indicator
with the back plug panel found in the storage box. Use the small screwdriver from the
storage box to unscrew the flat back panel. (Be careful to keep the screws.) Align the
back plug panel with the back of the indicator and replace the four small screws.
Usage
Unscrew the round thumbscrew from the Pivot Rod Clamp. Align the hole in the back
plug panel on the indicator with the hole in the Pivot Rod Clamp and replace the
round thumbscrew. Mount the Pivot Rod Clamp on a support (12 mm diameter).

About the Digital Indicator
The Digital Indicator has a four and one-half digit liquid crystal display (LCD), a
measuring head, lower sleeve, and three function buttons (ON/O, M, and mm/in).
Zero-setting can be done at any position of the measuring head to allow differential
measurement..
Function Buttons
ON/O: This is the “On-Off” and zero-setting button. If the indicator is off, press and
hold the ON/O button to turn the indicator on. Press and release the ON/O button to
set the zero point. Press and hold the ON/O button for several seconds to turn the indi-
cator off. (Note: The Digital Indicator has an automatic power off feature.)
M: This is the data hold button. Press and release to turn data holding ‘on’ and press
and release again to turn it off. (The interface software will continue to show the cur-
rent position of the measurement head.)
mm/in: This button toggles between measurements in millimeters and measurements
in inches. The default setting is ‘mm’. Press and release the button to switch to ‘inch’.
Press and release again to switch back to ‘mm’. Note that the DataStudio software
program used with a PASPORT interface is set to show millimeters (mm) or mils
(thousandths of an inch). Open the Experiment Setup window in DataStudio to select
the proper unit of measure.
Data Port
The data port is located on the left side of the Digital Indicator behind a small cover
labeled DATA. Slide the cover up to remove it (but don’t lose it). The data port
accepts the plug on the end of the Displacement Sensor cable.
Battery
Flashing digits show that the battery is very low. The Digital Indicator uses a 1.55 volt
SR44 silver oxide battery. To replace the battery, use the screwdriver to remove the
four small screws on the back panel and then remove the back panel. The battery is
under a circular cover. Loosen - but do not remove - the small screw that holds the
cover in place. Rotate the cover to the side and replace the battery (+ side facing up).
While holding the battery down, rotate the cover back into place. Tighten the screw,
put the back panel on, and install the four small screws.
Setup
Measurement Setup
Mount the Digital Indicator so that it is in contact with the object whose displacement
will be measured. Arrange the indicator so that the measurement head and lower
sleeve are aligned with the direction of the displacement.

If the object will be displaced both positively and negatively from its equilibrium
position, adjust the indicator so that the position of the measurement head when it is
in contact with the object is about halfway between the limits of the measurement
head’s travel. Press and release the ON/O button to zero the indicator when the mea-
surement head is at the equilibrium position.
Hardware Setup
The following three steps can be performed in any order.
1. Connect the cable of the Displacement Sensor (PS-2204) to the data port on the
side of the Digital Indicator. Turn on the indicator.
The connector on the Displacement Sensor cable fits into the Digital Indicator in only one way.
2. Connect the end of the PASPORT Displacement Sensor to a PASPORT interface.
3. If you will be using a computer, connect the PASPORT interface to the com-
puter’s USB port.
DataStudio Setup
If you will be using the PASPORT Displacement Sensor with a computer, install the latest version
of DataStudio first. Check the PASCO web site at www.pasco.com for information.
1. When you connect the PASPORT Displacement Sensor to the computer through
a PASPORT interface, the PASPortal window will launch automatically (if Data-
Studio is not already running).
2. Select Launch DataStudio in the PASPortal window.
A Digits display for displacement will open automatically.
3. Click to begin data collection.
You do not need to adjust the sample rate.
Xplorer, Xplorer GLX, and SPARK SLS Setup
If you will be using an Xplorer, Xplorer GLX, or SPARK SLS that is not connected to
a computer, connect the PASPORT Displacement Sensor to the interface and press
or to begin data collection.
NOTE: A green
light-emitting diode
(LED) on the Dis-
placement Sensor
flashes while the
sensor is connected
to a Digital Indica-
tor that is turned on.

Points of Attention
1. Keep the digital indicator clean. Prevent water and other fluids from getting into
the apparatus.
2. Never clean the indicator with organic solvents. Use alcohol containing no water.
3. Keep the data port cover in place when the data port is not in use. Never touch the
data port with any metal objects except the plug on the cable of the sensor.
4. Do not mark the digital indicator with an electric pen as this might damage its
electronic components.
