Dual Load Cell Amplifier Setup

Usage
The Dual Load Cell Amplifier and the Load Cells that connect to it are designed to
measure the tension or compression in beams from the PASCO Structures System.
(See the PASCO catalog online at www.pasco.com for information.)
Typical usage is to replace an element in a truss or bridge or other structure with two
smaller elements joined to a Load Cell that is connected to a Dual Load Cell Ampli-
fier that is connected to a PASPORT interface. The PS-2200 Load Cell’s range is from
-100 N to +100 N. The PS-2201 Load Cell’s range is from -5 N to +5 N.
About the Load Cell Amplifier
The Dual Load Cell Amplifier has a 16-bit analog-to-digital converter for a theoreti-
cal maximum resolution of 0.003 N when a PS-2200 Load Cell, 100 N is connected or
0.001 N when a PS-2201 Load Cell, 5 N is connected. The amplifier is lightweight
and travels easily when connected to a hand-held datalogger such as the Xplorer or
Xplorer GLX.
Load Cells can be connected to the Dual Load Cell Amplifier in any order. The maxi-
mum sampling rate is the same whether one or two Load Cell are connected.
Setup
Hardware Setup
The following three steps can be performed in any order.
1. Connect one or two separate Load Cells (PS-2200) to the individual input ports
of the sensor box.
Load Cells can be connected to either port in any order. The connector on the Load Cell cable fits
into the sensor box in only one way.
2. Connect the Dual Load Cell Amplifier 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 Dual Load Cell Amplifier 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 Dual Load Cell Amplifier 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 force will open automatically.
3. Click to begin data collection.
