System Description
This page describes the operation of a proof
test system for verifying the proof load of rope, wire rope, web
slings and other forms of rigging.
A multi-range load cell is used to measure the
force during the operation of the test system. The A2D Convertor
displays the force in pounds.
The A2D
Convertor is attached to one of the computer's standard serial
ports. The monitoring portion of the system uses Microsoft XP software
and Roberts Proof Test Certificate software for load data acquisition,
display, and the printing of a test certificate. The following
diagram illustrates this type of system:
During
a test, the system continually monitors the load, captures the
peak load, and displays the data in digital form. Once a test has
been completed, the operator can easily print a test certificate
(below) containing all pertinent data and a plot of the test load
vs. time.
A2D Convertor
With the A2D
Convertor, reading test results is simple and easy. The monitor
displays pounds of force.
An excellent feature of this A2D Convertor is
its separate peak/hold range. It resets automatically, assuring the
peak of the last test is retained.
Load cells and gauges are normally calibrated
for only 10% to 100% of their range. The lower 10% of a range is
usually neglected. With the Auto Range function, calibrating at the
lower limits is possible. The A2D Convertor automatically selects
between two ranges and allows the operator to test at lower levels
of force. The standard is 1% to 100% of the maximum range.
An RS232 output plug will be needed for connecting
a computer. If a computer is not wanted at this time, the RS232 output
plug is a very inexpensive way to plan for the future.
General Description of Software
This A2D Convertor is
compatible with Roberts Proof Test Certificate Software. This software
program prints a computer generated Test Certificate from the load
indicator of the actual load on the test machine. An RS232 output
plug is required for connecting the computer to the digital indicator.
Automatically Collects Test Data
Data available for recall
Saves time and reduces errors
Computer Hardware
It is preferable for the customer to buy their
own computer hardware. However, if desired, Roberts Testing
Equipment, Inc. will furnish the computer hardware and software
as a package.
Necessary hardware:
Computer with Mircosoft XP software and printer.
Year 2000 Compliance
