Our Principals

Environmental Data
Recorders which are self contained,
programmable electronic acceleration sensor/recorders. DynaMax analysis
software for time and frequency domains, SRS, and package drop
emulation. Records peak shock, acceleration time histories, strain,
pressure, temperature and humidity. Applications include:
transportation monitoring, cargo shipping and handling, accident
reconstruction, vehicle dynamics or characterizing actual environmental
and end use conditions.

The world standard in
transient recording. The PC
based systems offer high speed and multi channel solutions for capture
and analysis, desktop and notebook applications include shock and
vibration, drop testing and random vibration performance and process
monitoring. ProCAT 8 channel real time spectrum analyzer. Specific
recording and analysis capabilities offered include time domain,
frequency domain (FFT, PSD, transmissibility and coherence) and
Henderson-Piersol DP(f) fatigue domain. Linear shock & Rotary
shock
and vibration for hard drive and miniature products. ESSM
controlled-orientation freefall shock system directly reads velocity.

Designs and produces
Windows -based controls for
electrodynamic and servohydraulic vibration systems. VRC software
includes sine, sine sweep, random, classical shock, SRS, sine on
random, random on random and FDR (Field Data Replication from recorded
data). The FDR module uses three simultaneous control loops to correct
shaker system/product transfer functions allowing recorded field data
to replicate responses on product. KurtosionTM tailors the random
excitation to match field PPD. The result is random control with the
higher incidence of higher peak accelerations not generated with
traditional Gaussian random. TEDS accelerometer compatibility. Superior
reporting features. Best support and training in the industry. 3 year
Warranty.

Global provider of a full-line of high-performance, high-quality vibration testing systems from ranging from 40 to 77,000+ lbf with strokes up to 4 inches. Amplifiers certified by TUV SUD in Germany for EMC and safety. Simultaneous 3 axis shaker systems. Replacement amplifiers up to 300 kVA available for other manufacturers' shakers. ETS Solutions and other manufacturers' systems installed, refurbished, repaired and supported world-wide.
