Data Physics joins the LXI consortium

San Jose, CA – Data Physics Corporation became a member of the LXI consortium earlier this year as part of the strengthening of its commitment to the Ethernet as the architectural backbone for communication between Test & Measurement instruments. The Abacus hardware platform released in February 2003 at IMAC uses the Ethernet for connectivity to the host computer or other Abacus peripherals. Since its successful launch, over 10,000 channels have been installed worldwide.

Abacus is an architectural advance that overcomes the limitations of VXI and PXI for scalability of real-time measurements. Ethernet as an interfacing system offers several significant advantages: 1 Gbyte/s communication speed; up to 100m distance between the host computer and the measurement chassis; up to 150m separation of 32 channel Abacus peripherals synchronized in a system and simplicity and connectivity with multiple users via local area networks.

We are happy to see the evolution of the LXI communication standard following the arrival of Abacus, confirming our first instinct and endorsing the path we chose. Today, by formerly joining the LXI consortium, we are hoping to contribute to its further development and ensure customers will have access to products that not only rely on the best hardware platform for signal processing but also integrate easily as part of their labs. The LXI standard will permeate not only SignalCalc Dynamic Signal Analyzers and SignalStar Vibration Control Systems, which rely on Abacus, but also SignalForce power amplifiers.

Vibration Testing of Automotive Hybrid Control Modules

Hitachi Cable of Indiana recently commissioned their brand new Automotive Component test facility at New Albany, which was attended by the Indiana Governor, Mitch Daniels and other dignitaries. This new test lab includes a comprehensive vibration test system comprising a 222 kN (50,000 lbf) electrodynamic shaker with integral slip table and head expander to support testing of engine control modules and cable assemblies for hybrid automotive applications. The shaker is used to generate precise vibration patterns defined as Random Vibration with a defined Power Spectral Density and Overall RMS acceleration, Sinusoidal Vibration that sweeps from 5Hz to 2500Hz according to a defined acceleration profile, Mixed Mode with a Sinusoidal Sweep superimposed over Random, and Classical Shock pulses defined by the peak acceleration and pulse width duration. The shaker is a SignalForce Model 22260 from Data Physics Corporation built at their new Ling Electronics facility in Corona, California and is controlled by a SignalStar Vector Vibration Controller also from Data Physics Corporation.

The test system is capable of generating 222 kN (50,000 lbf) in Sine, 160 kN (36,000 lbf) in Random and can deliver 489 kN (110,000 lbf) of Shock force, which will allow testing at levels up to 100G at 11 ms half sine pulses in Shock operation.

Data Physics Files Suit Against Qualmark and Qualmark Ling

For Immediate Release:

San Jose, CA (Press Release) – Data Physics Corporation, a leading manufacturer of vibration testing equipment and systems, has filed suit against Qualmark Corporation and its subsidiary Qualmark Ling Corporation (collectively “Qualmark”), in Santa Clara California on numerous counts. Data Physics alleges, among other things, that Qualmark has committed unfair business practices, trade libel, unfair competition, and interference with Data Physics’ economic advantage. Data Physics also seeks cancellation of Qualmark’s California state trademark registration to the name LING ELECTRONICS because of its widespread and unregulated use in the vibration testing equipment field for over 50 years. Additionally, Data Physics incorporated its own Ling Electronics subsidiary almost three years prior to Qualmark’s registration of the trademark.

Data Physics’ Complaint notes that Qualmark Ling’s shaker operations have passed through three different owners in the last decade and that the quality and know-how once associated with the Ling name have been seriously degraded. Many employees from previous Ling operations now apply their unique knowledge and experience manufacturing shaker products and parts for Data Physics and its customers.

Sri Welaratna, Data Physics President and Chief Executive Officer, states that “An increasing part of our business is devoted to service and maintenance of the large install base of Ling shakers offered by a number of companies over the last fifty years. Because of the specialized knowledge and skills of Data Physics employees, we believe no other company can match our expertise in manufacturing and servicing Ling-compatible vibration test equipment.”

Data Physics has been a supplier of dynamic signal analyzers and vibration controllers for 24 years and began supplying total vibration test systems about five years ago. Today, Data Physics builds shakers in two factories, one located in California and one in the United Kingdom. Data Physics’ shakers are sold under the trademark SignalForce along with SignalStar vibration controllers and SignalCalc dynamic signal analyzers.

Data Physics is an ISO 9001:2000 certified company with a commitment to quality. Most importantly, its shakers are built by people who are passionate about shakers and have the knowledge and expertise to build them. Collectively, Data Physics employees have over 150 years experience in building water-cooled shakers.

Parts and Service

Data Physics also manufactures spares parts for all SignalForce and Ling shakers, including very old shakers built by Ling Electronics Inc. when the company was in existence. Data Physics also has a worldwide field service capability and in conjunction with its partner/distributors offers service for SignalForce, Ling, and LDS shakers that are compatible with Ling shakers.

New Southern California Facility to manufacture water cooled shakers

You know us for our vibration controllers. Now experience our comprehensive range of
shakers spanning 2 - 50,000lbf.

Data Physics opened its new shaker manufacturing operation in Southern California in December 2005. Staffed by highly experienced designers and craftsmen who worked for Ling Electronics in Anaheim, before the company was dissolved by Satcon, the Corona facility manufactures water cooled shakers to complement the air cooled shakers made at its Gearing & Watson facility in Hailsham, England.

The new water cooled models span the range of 80 KN (18,000 lbf) to 222 KN (50,000 lbf) and offer a direct replacement path for users of Ling 2016 to Ling 4522 range. Users will be pleased to hear that the armatures and field coils of the new SignalForce water cooled models are compatible with the Ling models. In addition to the new water cooled shakers, the Corona factory also manufactures armatures, field coils, flexures and other critical parts for all Ling shaker models, including air cooled shakers.

Data Physics has been a supplier of dynamic signal analyzers and vibration controllers for 23 years and began supplying total vibration test systems about five years ago; initially, the shakers were built by other manufacturers. In February 2004, Data Physics acquired Gearing & Watson, a 35 year old manufacturer of shakers in the UK. Data Physics shakers are sold under the trademark SignalForce along with SignalStar vibration controllers and SignalCalc dynamic signal analyzers.

Both Data Physics and Gearing & Watson are ISO 9001:2000 registered companies with a commitment to quality. You will now receive reliable shakers built to high standards. Most importantly the shakers are built by people who are passionate about shakers and have the knowledge and expertise to build them. Collectively, Data Physics employees have over 150 years experience in building water cooled shakers.

Parts and Service

Data Physics also manufactures spares parts for all SignalForce and Ling shakers including very old shakers built long ago by Ling Electronics when the company was in existence. Data Physics also has a worldwide field service capability and in conjunction with its partner/ distributors offers service for SignalForce, Ling and LDS shakers that are compatible with Ling shakers.
