  • Stand-Alone Doppler Current Sensor

    DCPS - Aanderaa Data Instruments AS

    The Doppler Current Profiler Sensor (DCPS) is a medium-range, 600kHz current profiler smart sensor. It offers high-quality ocean current measurements and is ideally suited for cabling directly to various systems or dataloggers via serial or AiCap bus. With its integrated compensation for tilting and movement, the sensor is commonly used to measure current from buoys and other moving platforms.The 5400/5400R version of the current sensor is 300m depth rated, the 5402/5402R version is 4500m depth rated, and the 5403/5403R version is 6000m depth rated and intended for commercial as well as research use. It comes with an integrated temperature sensor that can be calibrated on request.As an extension to the DCPS, we now offer the current profiler with an integrated pressure unit called the 5400P. This version enables acoustic wave measurements in addition to profiling currents. Ideal for small observatories, the DCPS sensor is the market's lowest-cost current and wave sensor.

  • Time-Resolved Electrochemical Quartz Crystal Microbalance

    400C Series - CH Instruments, Inc.

    The quartz crystal microbalance (QCM) is a variant of acoustic wave microsensors that are capable of ultrasensitive mass measurements. Under favorable conditions, a typical QCM can measure a mass change of 0.1-1 ng/cm2. QCM oscillates in a mechanically resonant shear mode under the influence of a high frequency AC electric field which is applied across the thickness of the crystal. Figure 1b below shows an edge view of a QCM crystal undergoing oscillatory shear distortion. The central portions of the top and bottom of the crystal are coated with a typically disk-shaped thin metal film (e.g., gold).

  • Real-Time Online Monitoring to Detect and Analyze Potential Partial Discharge (PD) Signals and Insulation Faults using UHF, AE, and HFCT
