Smithson & Associates

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.
