Microprocessor Based Digital Penetrometer
A new microprocessor based penetrometer loaded with advanced features to
provide ease of operation and highly reproducible consistency measurements of
petroleum products. Microprocessor control provides a full range of
measurement and reporting options, and operation is simplified by four user
programmable presets that facilitate lowering the penetrator tip to the
sample surface.
Automatically timed penetrations—The penetrometer defaults to the
standard ASTM interval of 5.0 seconds, or the operator may conveniently
program a different interval in the range between 0.1 and 9999.9 seconds (in
0.1 second increments). A curing or temperature stabilization period may also
be programmed by the operator (to delay the release of the penetrator into
the sample) and for added convenience all selected parameters are retained in
memory and automatically repeated in subsequent tests until changed by the
operator. Separate keypad controls for each parameter simplify operation. Penetration
and delay intervals count down on a large, easy to read LCD on the head of
the unit.
Convenient measurement and reporting options—Penetration measure-ments
in the full range of 0 - 620 in 1/10mm scale are reported in either 1/10mm or
1/100mm increments at the operator’s option. For quality control testing, a
penetration range can be entered into memory prior to testing. If a test
result falls outside of the programmed range, an audible signal and visual
error message alert the operator of a failed sample. Test results are
displayed in digital format on a large LCD readout on the head of the
penetrometer and can be communicated to a printer or computer via a built-in
RS232 interface.
Simplified penetrator tip placement—Correct placement of the penetrator
tip on the sample surface is essential for accurate penetration test results.
The Koehler Digital Penetrometer has four operator programmable presets that
lower the penetrator to the sample surface height at the touch of a button,
greatly simplifying the process to ensure reproducibility. A fine adjustment
button permits slight adjustments as needed. Full manual operation is also
available with the use of coarse and fine push button controls and built-in
magnifier and illuminator arms. When testing electrically conductive samples,
a built-in circuit senses the sample surface for automatic placement. After
testing, the penetrometer head returns to a raised position at the touch of a
button to facilitate cleaning of the penetrator and changing of the sample.
More convenience features—The detachable machined base provides a
large platform to accommodate a wide range of sample containers and constant
temperature cylinders. It removes easily to permit the head assembly to be
reversed (for use with a constant temperature bath) or mounted directly to a
bath housing or other location. A built-in rechargeable battery pack permits
field operation and provides back-up in the event of power interruption.
Battery recharges automatically during operation of the penetrometer on
standard AC electrical service.
