PCE Instruments
A decibel meter is a measuring instrument used to assess noise or sound levels by measuring sound pressure. Often referred to as a sound pressure level (SPL) meter, decibel (dB) meter, noise meter or noise dosimeter, a sound level meter uses a microphone to capture sound. The sound is then evaluated within the device and acoustic measurement values are displayed. Here at PCE Instruments, we offer two types or classes assigned to decibel meters: type 1 / class 1 or type 2 / class 2. For assessing noise in basic industrial, commercial, educational, recreational or residential applications, a type 2 / class 2 decibel meter usually will suffice. For precision-grade assessments often made in a laboratory, a type 1 / class 1 sound level meter primarily is used.

The TC4047 miniature hydrophone offers a useable frequency range from 1kHz to 170kHz. The hydrophone incorporates a high quality 20dB low-noise pre-amplifi er which provides optimal conditions for signal transmission. The high sensitivity provides excellent signal to noise ratio and immunity against induced cable noise. The hydrophone is omnidirectional up-to 100kHz and has uniform receiving characteristic from 1kHz to 100kHz. An insert calibration circuit enables remote testing of the hydrophone condition. The hydrophone comes with a SEACON connector. The sensor element is permanently encapsulated in Special formulated NBR to ensure long term reliability. The rubber has been specially compounded to ensure acoustic impedance close to that of water. The strainrelief and outer jacket of the cable is made of high density polyurethane. TC4047 can be used in sea or fresh water.

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.

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).
