Ling Electronics Shakers, Amplifiers, High-Intensity Sound Transducers
Looking for Ling Electronics shakers, amplifiers, high-intensity sound transducers, or service? You can find them here.
In 2009, Data Physics acquired Ling Electronics from Qualmark. The legendary Ling Electronics products have become the Data Physics “LE” product range – continuing a legacy of quality and performance in environmental vibration testing that you can trust.
Out With The Old, In With The New
Earlier this week we completed the upgrade and replacement of an original Ling amplifier that was powering the very first Ling 540 with a build date of June 1988! Ling started numbering their products at 11 so that no one thought that they got the very first one.
After servicing the DMA 12-12 amp that was powering the Ling 540 shaker for many years, the difficulty in finding replacement parts and the increasing amount of downtime meant that it was time for an upgrade.
Since Data Physics acquired the assets of Ling Electronics in 2008 we were the natural choice to provide a fully compatible IGBT based amplifier that would allow this old Ling to keep on shaking to it original specifications.
While the Ling 540 was still working well, the customer wanted to plan for a future shaker upgrade that could provide a full 3” of stroke, better sine, random and shock performance, better performance at higher frequencies and vastly better energy efficiency.
With this in mind, the amplifier was designed to be fully compatible with the Ling 540 and the current generation Data Physics LE-1316-3 shaker.
Now, when the customer upgrades the shaker, they will not have to buy a new amplifier! This type of strategy provides the ability to keep their current shaker running until they are ready for their new LE-1316-3 shaker and allows the cost of a full shaker upgrade to be spread across different fiscal years budgets.
Data Physics can build a new amplifier for virtually any Ling shaker while providing a straight-forward and cost-effective upgrade path to a new shaker. Let us know what we can build for you!
How to Select the Right Power Amplifier
Data Physics provides robust, reliable and efficient amplifier products that supply the power used to drive your test system to its limits. When selecting an appropriate amplifier, you need to consider the mass of your shaker’s armature, head expander, device under test and your test performance specifications, as these variables dictate overall power requirements.
When considering what power amplifier is applicable for your testing needs, it’s important to remember Newton’s 2nd Law of Motion…the simple equation:
F=ma, or Force = Mass x Acceleration
Force: is the required force of the shaker for the given acceleration and mass. Vibration systems have different force ratings for Random, Sine, and Shock.
Mass: is the total moving mass including the shaker’s armature. The DUT, fixture, head expander (if applicable) or slip table + drive bar + bearings, and the shaker’s armature all add into the mass.
Acceleration: is given by the profiles to be tested, typically units of g for Sine and Shock, and g rms for Random.
Increase Your Shaker’s Performance with SignalForce IGBT Amplifiers
Designed with the Data Physics LE-series shakers in mind, the new LE-DSA15 IGBT amplifiers are based on the same reliable and robust architecture as the LE-DSA10 series units, which have a proven track record of continuous high output operation. The LE-DSA15 amplifiers are rated for 200 Vrms continuous operation which will allow for high velocity testing without the need for an output transformer – saving floor space.
When connected to a LE-DSA15K amplifier, the LE-2016-3″ shaker systems are capable of up to 170 in/sec (4.32 m/s) velocity shock at 11 mSec.
IGBT Advantages
- Improved Shaker Performance
- Reduced Energy Consumption
- More Reliability and Stability
- Lower Operating Costs
- Simplified Shaker Operation
- Reduced Floor Space Requirements
A Powerful Upgrade for Any System
Our new LE-DSA15 amplifiers are the perfect fit to replace an aging amplifier that is currently driving either a Ling Electronics or LDS shaker system, enhancing the performance of the system in both random and shock performance.
The LE-DSA15 models can be configured to drive any manufacturer’s shaker system with the proper field power supply configuration.
Less Is More
The elimination of the output transformer allows the shaker to be direct-coupled, making it possible to operate the shaker at less than 5 Hz.
The transformerless design also eliminates the need for switching for sine, random, and shock profiles. The overall size of the amplifier is thus reduced, freeing up valuable floor space in your vibration test laboratory.
About Data Physics
Data Physics, owned by Battery Ventures, was founded by two Alumni of Hewlett Packard in 1984. Dave Snyder had designed hardware and software for the Fourier Analyzers developed at the Santa Clara Division of HP. Sri Welaratna had worked for HP in England, Europe and then in Santa Clara developing applications of Fourier Analyzers. The first project Dave and Sri did together was the design of the UD 400AT vibration controller, the first to use a PC as the host computer and a DSP based signal processing peripheral. This project began in 1983 and used the Texas Instruments TMS32010, the very first Digital Signal Processor.
Starting with the SignalCalc software library for HP Basic computers Data Physics evolved to signal processing solutions on PCs using add on DSP hardware to provide the computational power required for realtime measurements and analysis.
In 2014, Battery Ventures bought a controlling stake in Data Physics. DP is the fifth active industrial-technology platform in the Battery portfolio. In 2015, Battery Ventures acquired a controlling stake in both Lansmont and Team Corporations, establishing the foundation of the Noise & Vibration Technologies (NVT) Group.
