Modernization of Pendulum Impact Testers PSd 150/300

• The installation of an incremental transducer and a digital controller significantly improves the stability of function of measurement and regulation of the test procedure
• By renewing the pendulum lifting and applying a stronger motor, the load-dependency is almost removed and the set point are reached more accurately.
• Refitting of the magnetic coupling to an electro-magnetic brake mechanism, provides more safety, above all in case of power failure.
• By renewing the operating panel, the operating concept is extended (service mode for calibrating the pendulum impact tester), an electric safety release of the pendulum is installed.
• Thanks to the new data interface (Ethernet), it is possible to connect a computer, the operator can record, process, archive and transfer impact test results with the computer and software ImpaSax. The integration in an in-house quality management system is therefore guaranteed.

Digitalization of Pendulum impact testers PS, PSW, PW etc.

• The pendulum impact tester is equipped with an incremental transducer and a digital controller. This significantly improves the stability of function of measurement and regulation of the test procedure.
• With the renewed Ethernet interface it is possible to connect a computer. With the computer and the software ImpaSax, acquisition, calculation, archiving and transfer of the test results can be carried out. The integration in an in-house quality management system is therefore guaranteed.

Upgrade to latest safety standards according to DIN 51233

Older pendulum impact testers, e.g. PSW 300 or PS 30, can be upgraded by Kögel to meet the safety requirements of the Machinery Directive 2006/42/EC and DIN 51233. Thanks to this safety upgrade, a CE sign can be added to the pendulum impact tester.

Depending on the model, the following components and options for the upgrade are available:

• Safety enclosure: The safety enclosure can be completely closed or can be equipped with opening for operation. A closed safety enclosure can be equipped with one or two doors (one door to insert the specimen and one door to remove specimens). Optionally available pivoted hoods make maintenance and calibration much easier. Thanks to locking switches for the doors (currentless closed), the pendulum can only be released when both doors are closed and locked. The door can only be opened, when the pendulum is in inoperative position.
• Securing the latched pendulum by locking bolt
• Light barrier to monitor the inoperative Position
• Emergency stop button
• Brake button to brake the hammer after the Impact
• Switch cabinet with monitoring electronics
• Trailing pointer replaced by an operating panel

New components are used:

• Hydraulic unit/electro-mechanic drive
• Control valve at the hydraulic unit
• New hydraulic clamping device
• Replaced load cell/force transducer
• Installation of a new electronic position measuring system
• Replaced measuring and control device
• PC and software for WINDOWS (optional)

Your modernized testing machine offers:

• Comfortable operation
• Constant measurement results
• Interface for test report printout
• User-friendly evaluation of measurement results with PC
• More space since old control is not necessary anymore
• Cleanness thanks to improved hydraulics
• High resolution of measured values (corresponding to latest technical development)
• Test control with force, displacement, elongation (can be switched without shock during the test)
• Ramp programming with selectable rise and hold time

By modernizing your testing machine, alle requirements according to EN ISO 7500-1 concerning force measurement unit and EN ISO/IEC 17025 concerning calibration and testing possibilities are fulfilled. Individual adaptations for your test tasks are possible.

Example: 2 MN deadweight force standard machine

• Generating force by standard weights
• Automated calibration cycle
• Renewed hydraulic system
• Application of a digital control

The hardness testers of VEB Werkstoffprüfmaschinen Leipzig, Karl Frank GmbH and other manufacturers are robust and widely used devices. By means of a modernization, we bring these devices up to the cur-rent state of the art. This gives you a modern, reliable and future-proof hardness tester that can still be calibrated.

With the digitalization box, Rockwell hardness testers such as HP 250, HM 1810 and HM 1830 can be digitized and modernized. Brinell/Vickers devices, such as the HPO 250, can also be digitized in conjunction with a digital caliper.

The digitalization box replaces your old measuring system and meets the requirements of the current standards ISO 6508 and ISO 6506. With this conversion, you can continue to test in accordance with the standard with your hardness tester. For Rockwell devices you achieve a measurement accuracy of 0.05 HRC.

The digitalization box also contains an interface for data transmission, which enables the measured values to be transmitted directly to third-party systems for data acquisition and analysis. To do this, the measurement data is exported from the digitalization box to your Excel template, which you can then evaluate there. This allows you to digitally store and process your measurement data in order to optimize the quality of your test processes.
