Experience

We have more than 20 years of experience in the piezoelectric accelerometer design, especially in harsh and high temperature environment (500°C, 700°C or even more).

In order to maintain our international expertise we closely work with two university laboratories LCEP ( http://www.lcep.ens2m.fr ) and LPMO ( http://www.lpmo.edu ) based in Besançon and specialized in Piezoelectricity.

We also have the chance to be located in a region where piezoelectricity, microtechnics, microelectronic, mechatronic, microsensors and precision are well known words. Besançon hosts one of the biggest microtechnology fair in Europe ( http://www.micronora.com ) devoted to microtechnology and strong of 850 exhibitors from 25 countries.

All this friendly environment strengthens our knowledge and gives our company a competitive advantage in the piezoelectric vibration sensor technology.

Technology

With advanced product development and manufacturing facilities in Besançon-France, VibraSens has the skills, experience and resources to provide the products and services that will fulfill your requirements.

A modern production facility exclusively engaged in the design and manufacture of piezoelectric vibration transducers, piezoelectric pressure sensor and vibration instrumentations help us to maintain a high quality level in our core business.

Our manufacturing and test equipment ranges from basic precision machinery for providing high quality sensor components, to custom-built machinery specifically designed for piezoelectric vibration sensor fabrication.

During the years of development we have also built some specifically design systems to test our range of piezoelectric accelerometer.

ACCELEROMETER TECHNOLOGY SELECTION

If you want to assess the motion of an object then you need a sensor to do it. There are many styles like for example the eddy current probe, the velocimeter, the laser or the accelerometer. All have their output proportional to the motion of the object let it be acceleration, velocity or displacement. All have their own characteristic in terms of temperature, frequency response, linearity, sensitivity, etc. The accelerometer have proved to be successful in many applications.

Accelerometer exhibits 3 technologies:

(1) ®ICP is a worldwide voltage transmission standard that uses a constant current source supply. Some manufacturers still offer proprietary current transmission which is not useful for standard application: AC acceleration up to 10 kHz and 500 meters, AC velocity up to 5kHz and 1000 meters, displacement up to 1kHz and 2000 meters.

(2) The AC acceleration signal can be externally conditioned to have concomitamment AC velocity, AC displacement, DC acceleration, DC velocity or DC displacement.

(3) With no AC acceleration output, you will not be able to connect a portable analyzer with envelopping algorithm for roller bearing defect detection.

(4) Resolution is important if you plan to make measurements at low frequency (<10Hz) with vibration parameters like velocity or displacement.

(5) This type of sensors covers the broadest range of characteristics: few grams to kilograms, epoxy or hermetically sealed, large choice of connector, top or side connector,.....

Model 101.01-A-2 with Overmolded M12 cable assembly

Description

The hermetic sealed industrial piezoelectric accelerometer model 101 is design to monitor the vibration in harsh industrial environment. It uses the industry standard ©ICP 2-wire voltage transmission technique with a 4 mA standard constant current supply. Signal ground is isolated from the mounting surface and outer case to prevent ground loops. Faraday shielding will limit sensitivity to EMC to a minimum. Annular shear mode design will prevent from thermal transient and from spurious signal from high transverse vibrations. Low noise electronic and a temperature compensated design will give you accurate result over the complete temperature range. Large choice of frequency range will help to fit almost every customer requirements. Low frequency accelerometers (A=9 & 0) incorporate a low-pass filter within the conditioning electronic. This filter attenuates the sensor mechanical resonance and the associated distortion and overload.

Typical applications

Vibrations measurement in the rugged environments of industrial machinery monitoring. High frequency version monitor the vibration on roller bearing, pumps cavitation, .... Medium frequency version monitor overall vibration on pumps, motors, fans, ... Low frequency model is used in the petrochemical, machine tool, and paper industries for monitoring of slow speed agitators, cooling towers, ... High temperature version is typically used where extra temperature protection is needed, such as the dryer section of a paper machine.

It uses the industry standard ®ICP 2-wire voltage transmission technique with a 4 mA minimum constant current supply. Signal ground is isolated from the mounting surface and outer case to prevent ground loops. Faraday shielding will limit sensitivity to ESD to a minimum. Annular shear mode design will prevent from thermal transient and from spurious signal from high transverse vibrations. Low noise electronic and a temperature compensated design will give you accurate result over the complete temperature range. Large choice of frequency range will help to fit almost every customer requirements. Low frequency accelerometers (A=9) incorporate a low-pass filter within the conditioning electronics. This filter attenuate the sensor mechanical resonance and the associated distortion and overload.

Model 105.01-A-2 with Overmolded M12 cable assembly

Description

The sealed industrial piezoelectric accelerometer model 105 is design to monitor the vibration in harsh industrial environment. It uses the industry standard ©ICP 2-wire voltage transmission technique with a 4 mA standard constant current supply. Signal ground is isolated from the mounting surface and outer case to prevent ground loops. Faraday shielding will limit sensitivity to EMC to a minimum. Low noise electronic and a temperature compensated design will give you accurate result over the complete temperature range.

Economy compression mode accelerometers should not be used whenever thermal transient, high transverse vibrations or high base strain are present. Compression accelerometers are also not recommended for low frequency (<1Hz) measurements. In such environments model 101 (annular shear mode) is prefered.

Typical applications

Vibrations measurement in the rugged environments of industrial machinery monitoring. High frequency version will monitor the vibration on roller bearing, pumps cavitation, .... Medium frequency version will monitor overall vibration on pumps, motors, fans, ...
