Piezoelectric Triaxial Accelerometers

Our piezoelectric (PE) Triaxial accelerometers are used for capturing the full motion or vibration profile of the test object and measure acceleration in three orthogonal axes (X, Y and Z).

Applications of use include structural health testing and monitoring, vibration analysis, laboratory studies and modal testing in the Aerospace, Automotive, Civil Engineering, Environmental and Transportation Industries.

The Metromatics Series MM242A, MM243A, and MM245A are Piezoelectric Charge Mode Triaxial Accelerometers.  Measuring acceleration, vibration or motion simultaneously along the three axis.

How it operates

Firstly, in a triaxial accelerometer, there are three such piezoelectric setups, each oriented along one of the three orthogonal axes (X, Y, Z).  However, at the core of each axis sensor is the piezoelectric sensor.  The sensing element in them generates a charge is proportional in response to acceleration or vibration.

Secondly, charge-mode accelerometers output a raw charge signal. Therefore, this signal is fed into an external charge amplifier.  So, it can be converted into a voltage signal that can be more easily processed and transmitted.  Once signal conversion is complete, signals move to data acquisition systems for further analysis. In addition, because it has no built in electronics, charge mode accelerometers are often more stable over a wider temperature range.

This series has a measuring range of 2 to 100 pC/g.  Along with a resonant frequency range of 8KHz to 25KHz which offer accurate and reliable acceleration measurements.

Finally, these accelerometers are made from stainless steel or titanium providing true durability allowing the sensor to operate in conditions from -54 to +150°C making them suitable for a broad range of applications.
