1 Introduction
Thank you for purchasing an ultrasonic hardness tester from PCE Instruments.
The ultrasonic durometer is a device, based on a patent filed in 1961. Therefore the hardness
measurement is performed through a diamond placed on a spring. Due to its design and measurement
method, the ultrasonic durometer allows a simple and non-destructive analysis of metallic objects. The
ultrasonic durometer enables measurements on various construction parts, since it is programmed to
measure with different SI-units, the most common of which are the hardness scales according to
Rockwell, Brinell and Vickers. Featuring a RS-232-interface the ultrasonic durometer PCE-5000 can be
connected to a computer in order to read out and print out the measured data. The ultrasonic durometer
allows a detailed overview of all the data, since it can record even the thresholds as well as mean values.
The mean value is automatically generated as soon as more than one measurement is performed with
the ultrasonic durometer PCE-5000. Its design allows reaching even locations that would be otherwise
hard to reach, and it allows reviewing and reading the values comfortably at its graphic display. Due to an
option to calibrate, the ultrasonic durometer can be always calibrated by the user at any time. A
calibration might be necessary, if for example the last measurement was more than three months back, or
when the environment is significantly different from before, if the ultrasonic sensor has already performed
a major amount of measurements, or if the measurement of a defined calibration object shows a
divergent.
Range of use
- Hardness measurements of the flanged edge and gear root stamping, mold, sheet, surface
hardened tooth and gear groove
- Hardness tests of central axes, thin-walled pipes and vessels
- Hardness testing of tires and turbine rotor
- Hardness tests of cutting blades
- Hardness testing of welded parts
- Hardness tests of certain opening depths, convex depressions, irregular levels
- Hardness tests of most ferrous and non-ferrous metals and other alloys in industrial production.
2 Safety notes
Please read this manual carefully and completely before you use the device for the first time. The device
may only be used by qualified personnel and repaired by PCE Instruments personnel. There is no
warranty on damages or injuries caused by non-observance of the manual.
- The device may only be used in approved temperature range
- The opening of the case should only be done by qualified personnel of the PCE Instruments.
- The instrument should never be placed with the user interface (e.g. keyboard side on a table)
- You should not make technical changes on the device
- The appliance should only be cleaned with a damp cloth / use only pH-neutral cleaner
- Do not shake the device since internal components may get damaged.
- Do not scratch objects with the diamond.
- Do not disassemble the unit. Otherwise the warranty will expire.
- Do not use the instrument under inflammable air environment, otherwise it may take fire or
explode.
The ultrasonic hardness tester is a precision instrument that must be used with extreme care to avoid
damage and associated measurement error.
Remove the diamond indenter mentioned above for about half a second after each measurement and
then make a new measurement. Otherwise, the device cannot resonance between the indenter and a
single sample in a short time.
Please ensure that after each use, the device is always kept in the respective carrying case. Avoid
accidents and collisions.
Do not disconnect the probe from the main unit, since otherwise the device loses its functionality.
Do not use the product near flammable gas, as this could result in fire or explosion.

3 Specifications
There are different kinds of methods for measurement of hardness:
Brinell, Rockwell, Vickers, Leeb, etc. are usually used.
Rockwell and Brinell tests force with larger test loads and large stamps what often leads to visible
damage to the material surface. The hardness-measuring of heavy work pieces, built-in machinery and
permanently assembled parts is therefore relatively difficult.
The ultrasonic hardness tester PCE-5000 uses the Ultrasonic Contact Impedance procedure to carry out
comparative hardness measurements for test pieces, with the advantages of a highly accurate, efficient,
portable and non-destructive measurement with simple operation.

Ultrasonic indenter and recesses
During
measurements the inspection stamp entrudes minimally within the material. The indentation depth (H)
and the mean value of the dialog lengths (d) of the various probes of the ultrasonic hardness tester can
be reduced with increasing value.

Minimum thickness of the tested object
Despite the low penetration depth the workpiece needs to have a minimum thickness so that the
instrument is not damaged. The minimum thickness of the material should be at least ten times higher
than the penetration depth.

Condition of the surface
The applied test force (i.e. the selected UCI probe) must not only match the application but also the
surface quality and roughness of the material. While smooth, homogeneous surfaces with low test loads
can be measured, rougher surfaces and coarse-grained require measurements with high test loads.
However, the surface must always be free of contaminants (oil, dust, etc.) and rust.
Dimensions and weight of the part to be tested
From the above analysis, all probes request coating layer or surface layer less than 1 mm. The hardness
value will change if there is resonance. The highest value of vibration is the elastic oscillation, where
some actions can be made in order to restrain these. To do so the piece has to be put on thicker metal.
Rubber and oil can restrain elastic waves. It is recommended to use pieces that have a thickness of 2…3
mm and a size, which is not less than 5 x 5 mm.
Also the weight of the material is important. Depending on the weight certain preparations have to be
made:
Weight
