Linear Velocity Transducers Series 100 Linear Velocity Transducers The Series 100 Linear Velocity Transducers are inductive, instantaneous velocity transducers.

Transducers, Velocity & Position Sensors LVDT sensors by Trans-Tek

By moving a magnet through a pair of series opposed coils, the transducer will output a DC voltage proportional to the instantaneous velocity. No excitation voltage is required. Available ranges are from 0.5" to 24.0". *** NIST type calibration now available for LVTs - Request Sales Option X0072 *** Main Features: Extension Rods & Cores also available with Metric Threads.

Force Transducer / Force Sensor - HBM force measurement. Measuring vessel speed and sound velocity. In close collaboration with laboratories, companies and military outfits all over the world, we have developed an advanced line of transducers and hydrophones covering a frequency range of 0.1Hz to 2MHz.

measuring vessel speed and sound velocity

Ideal for measuring vessel speed and sound velocity, and flow, level and current in water, our transducers are precision instruments that have simplified and optimised communications, navigation, positioning and echosounding for more than 25 years. That’s a wealth of experience. Our in-house specialists are always on hand to share what they know, and help make sure your next expedition achieves its goals. The transducers fall within the following categories: 1000 Series – Hemispherical, broad band. Find help in our wiki. Read the catalogue for our standard transducers and hydrophones. LEM – current transducer, voltage transducer, sensor, power measurement. Airmar Technology Corporation » The Leader in Ultrasonic Transducers and Sensing Technology. Piezoelectric Transducers. Piezoelectric: The generation of electricity or of electric polarity in ceramic dielectric crystals subjected to mechanical stress, or the generation of stress in such ceramic crystals subjected to an applied voltage.

Magnetostrictive: Deformation of a ferromagnetic material (such as iron and steel) subjected to a magnetic field. Piezoelectric Transducers The conversion of electrical pulses to mechanical vibrations and the conversion of returned mechanical vibrations back into electrical energy is the basis for ultrasonic testing. The active element is the heart of the transducer as it converts the electrical energy to acoustic energy, and vice versa.

The active element is basically a piece of polarized material (i.e. some parts of the molecule are positively charged, while other parts of the molecule are negatively charged) with electrodes attached to two of its opposite faces. Piezoelectric Effect (PPT, 89kb) Piezoelectric Elements (PPT, 178kb) Piezo Transducer. Contact microphone assembly There are too many posts on alt.noise concerning how to build contact microphones, and to my knowledge, nobody ever posted a page like this in response.

Piezo Transducer

Plenty of bad advice out there… Hopefully this page is a little more useful than some of the responses I have seen over the years. If you actually follow these directions. This is one way to put together a contact microphone. It is not the best way, but the end result is pretty satisfying. Here are a couple of interesting ideas on improving this design that were sent to me. Radio Schlock parts list: Piezo Transducer 273-073A Two conductor inline 1/4″ Phone Jack 274-340A 24AWG “audio cable” 2 conductors plus shield part no. 278-514 Heat shrink tubing. The functional element – a piezo electric transducer is commonly used as the speaker. Different models come in different plastic packaging, each more annoying to excise than the other.
