  • Profiling CTDs

    Sea-Bird Scientific

    A CTD measures Conductivity, Temperature, and Depth. Despite the name, all CTDs actually measure pressure, which is not quite the same thing as depth. The relationship between pressure and depth is a complex one involving water density and compressibility as well as the strength of the local gravity field. The CTD data can be used to calculate salinity, density, sound velocity, and other parameters of interest. The term CTD is often used today to describe a package that includes the actual CTD as well as auxiliary sensors to measure other parameters (such as dissolved oxygen, pH, turbidity, fluorometer, altimeter, etc.) and a water sampler to collect water samples for later analysis in the lab. The term Sonde is sometimes used as an alternative to CTD.

  • Vibration Testing

    Response Dynamics Vibration Engineering, Inc.

    We most often characterize a problem first and work from known conditions, and stay in “the known” as we proceed by making sense of what we observe as we move forward. We test and analyze the change in dynamics we are trying to create in real-time, on site, and often make changes to our experimental test plan on the fly as we discover how a system is actually behaving. In doing so we often get meaningful results from which we can make sound engineering decisions in a short time frame. We don't just make measurements and spit out data. We help identify the problem and propose solutions.

  • Motor Vibrophonic Monitor

    MV-90 - ECG KOKUSAI Co., Ltd.

    A very small acoustic vibration during operation can indicate a major defect in a small-sized precision motor. The acoustic vibration is normally detected using a sounding bar applied to the ear of an inspector who judges whether to reject or pass a motor by listening to its sound during operation.This method produces different judgments according to each individual inspector, and automation is not possible. With this unit, a highly sensitive acceleration-type detector is applied to the bearing area of a motor, to directly defect the acoustic vibration.The resultant measurement is not influenced by environmental noise, and an absolute and accurate measurement can be made.

  • Suspension Component Test Systems

    MB Dynamics Inc.

    Acoustic quality, vehicle dynamics and stability, and driver comfort play an increasingly important role in the development of new chassis and suspension systems – both passive and active. Noises in suspension components can cause customer dissatisfaction and lead to high warranty costs and are difficult to diagnose especially on historically-used, noisy hydraulic test rigs. The MB Suspension Component Test Rig (SCTR) enables dynamic simulation of real road excitations and synthesized waveforms, performing industry-standard Force-Velocity and Force-Displacement tests and low speed friction tests, and assessing other NVH and structure-borne noises for comprehensive performance characterization and sound and vibration analyses on a wide variety of chassis components.

  • Turnkey Solution for Unattended Noise Monitoring

    NoiseScout - NTi Audio AG

    NoiseScout provides a comprehensive but easy-to-use 24/7 noise monitoring solution. Noise levels are recorded on-site by the XL2 Sound Level Meter and are available online for monitoring and download. NoiseScout is aimed at both short term noise assessments and long term monitoring applications. During acquisition, automated email alerts allow noise issues to be addressed before a non-compliance condition arises. NoiseScout displays the noise levels measured by the XL2 Sound Level Meter live in your web browser. The measurement data recorded out in the field is presented online in charts and dashboards. Multiple noise level meters can be monitored simultaneously within the map view, thus providing localized geographic visualization for all noise levels at a glance. Identified users can access all their projects, control their monitors or create basic view modes, allowing stakeholders to oversee their noise level data.
