DESCRIPTION
The Model P3 Strain Indicator and Recorder is a portable,
battery-operated instrument capable of simultaneously
accepting four inputs from quarter-, half-, and full-
bridge strain-gage circuits, including strain-gage-based
transducers. Water-resistant grommets in the hinged
cover allow the lid to be closed with leadwires attached.
Designed for use in a wide variety of physical test and
measurement applications, the P3 functions as bridge
amplifier, static strain indicator, and digital data logger.
The Model P3 Strain Indicator and Recorder, utilizing a
large LCD display for readout of setup information and
acquired data, incorporates many unique operating
features that make it the most advanced instrument of
its kind. An extensive, easy-to-use menu-driven user
interface operates through a front-panel keypad to readily
configure the P3 to meet your particular measurement
requirements. Selections include active input and output
channels, bridge configuration, measurement units, bridge
balance, calibration method, and recording options,
among others.
Standard sensor input connection is via eccentric-lever-
release terminal blocks. Optional transducer connection
is available via side-mounted bayonet locking circular
connectors.
Data, recorded at a user-selectable rate of up to 1 reading
per channel per second, is stored on a removable flash
card and is transferred by USB to a host computer for
subsequent storage, reduction and presentation with the
supplied software.
The P3 can also be configured and operated directly from
your PC with a separate software application included
with each instrument. Additionally, a full set of ActiveX
components is provided for creating custom applications
in any language supporting ActiveX.
A highly stable measurement circuit, regulated
bridge excitation supply, and precisely settable gage
factor enable measurements of ±0.1% accuracy and
1 microstrain resolution. Bridge completion resistors of
120, 350 and 1000 ohms are built in for quarter-bridge
operation. Also, input connections and switches are
provided for remote shunt calibration of transducers and
full-bridge circuits.
The P3 operates from two readily available D cells.
Battery life depends upon mode of operation but ranges
up to 600 hours of continuous use for a single channel. It
can also be powered by connection to an external battery
or power supply, a USB port on a PC or with an optional
external line-voltage adapter, the Model P3-A105.
