TECHNOLOGY AND INNOVATION DRIVES OUR SUCCESS In 1993, only two years after I came to the USA, I read about a new technology that was just introduced into the consumer industry. Microsoft began to support the sound card with their early version of Windows. A small start-up company, m-Wave (I still remember its name), used an ADC chip which claimed to have a digital (instead of analog) anti-aliasing filter. When I looked at the existing dynamic measurement instruments, I found that the size of their digital processors was getting smaller and smaller. But the analog circuitry (and its...

The CoCo-80 was a great success owing to this concept. With two different working modes, one device performs simple route data collection or advanced acoustic real-time processing. It speaks to its user in familiar words which he understands in both cases. While we were designing the portable vibration analyzer, we became aware of a high-resolution measurement technology developed by Cisco that acquired and analyzed radio-frequency data using multiple A/D converters. In the same era, Bruel & Kjær introduced its Dyn-X® front-end that claimed very high dynamic range in the measurement....

TIMELINE OF ACHIEVEMENTS ■■ 1996: Crystal Instruments released the world’s smallest dynamic signal analyzer in a type-II PCMCIA form factor. It was the first vibration analyzer in the world using sigmadelta A/D converters. ■■ 2007: Crystal Instruments introduced the CoCo-80, the first handheld data recorder, real-time dynamic signal analyzer, and vibration data collector that matched the performance of high end lab quality instrumentation. ■■ November 2007: The US patent office granted Crystal Instruments an important patent, #7302354. This innovation provided an advanced technique that can...

INDUSTRIES WE SERVE MACHINE CONDITION MONITORING Smooth running process machinery buoys and maintains the world’s economy. Products ranging from gasoline and chemicals to paper and steel are produced by continuous manufacturing processes. Nuclear, coal-fired, natural gas fueled, hydroelectric, wind powered or tidal-driven, power generation plants must produce continuously. Unexpected stoppages are the anathema of all these industries and vibration monitoring is a proven means of preventing them. Effectively monitoring the operating health and rapidly diagnosing the occasional mechanical...

AUTOMOTIVE Automotive applications span a broad range of technology from design through product quality auditing. Manufacturers are under enormous competitive pressure to provide increasingly improved quality, safety, mileage, luxury, and economy. This places a heavy burden on automotive NVH Engineers to accomplish more, faster. Fast-paced development cycles in the modern car, truck, and coach industry demand the use of functionally flexible measurement equipment with friendly intuitive operation to unravel the dynamic and acoustic mysteries of the modern vehicle. Data Acquisition and...

MILITARY The military forces of the United States design and acquire a variety of specialized hardware and systems for use on land, in the air and at sea. Military acquisitions range from miniaturized electronics packages to surface ships and aircraft. All of this material is subjected to rigid incoming inspection and testing in accordance with military specifications. Data Acquisition and Analysis ■ Ship and submarine silencing ■ Helicopter and jet vibration ■ Vehicle dynamic strain recording ■ Flight/road test recording ■ Engine/driveline analysis ■ Route-based vibration data...

VIBRATION CONTROL SYSTEM HARDWARE PLATFORMS INTRODUCTION In shaker vibration testing, the device-under-test (DUT) is rigidly mounted to the table of an electrodynamic (or hydraulic) shaker. A closed loop control system causes a test object to experience a prescribed vibratory motion of sinusoidal, random or transient form (or a combination of these). How well this is done is determined by the controller’s hardware, firmware and architecture. How simply and elegantly it is accomplished is determined by the system’s software. Crystal Instruments provides the most highly advanced shaker...

Analog Input Amplifier Amplifier Hardware per US Patent 7,302,354 applies two ADCs to each input channel. Converter Converter Digital Output The DSP knows how to pick the data from either A or B path, and "stitch" them together. High Precision Front-End Design The Spider analog input channels provide extremely high precision measurements. Each channel has single-ended or differential AC or DC input coupling. It can also provide IEPE (ICPTM) input mode (AC coupling with a 4 mA constant current from a 24 VDC source) for use with industry-standard accelerometers with built-in amplifiers....

On-Board LCD Display The Spider-81 and 81A are equipped with a bright front-panel LCD and intuitive information navigation controls. Real-time status such as control RMS or sweeping frequency is instantly viewed on the LCD. Designed for High Reliability The Spider is the very first vibration control system designed for fail-safe operation even in the event of network or power loss. Advanced safety routines allow sensor failures to be detected within milliseconds. All Spider hardware passes strict environmental tests including EMI, temperature, drop shock, sine and random vibration. The...
