IEPE Single Axis General Purpose Accelerometer

IEPE Single Axis Accelerometers

Our piezoelectric (IEPE) Single Axis accelerometers are generally used in applications where they are well suited for dynamic measurements across wide frequency range and tolerant of noisy environments.

Applications of use include vibration monitoring and analysis, structural health monitoring and automotive testing.

The Metromatics Series 121A and 122A are IEPE Single Axis Accelerometers.  Measuring acceleration or motion along only one axis.  For example, in one of the three dimensions being X-Axis (horizontal), Y-Axis (Vertical) or the Z-Axis (depth).

How the IEPE Single Axis Accelerometers operate.

The sensing element in them generates a charge in response to acceleration.  The built in electronics converts the high impedance charge signal generated by the piezoelectric element into a low impedance voltage signal. Once signal conversion is complete, signals move to data acquisition systems for further analysis. In addition, the sensor is robust against noise making it suitable for dynamic measurements across a wide frequency range.

This series has a measuring range of 5 to 500 g/pk.  Along with a frequency range of 0.2KHz to 12KHz which captures and measures vibrations and accelerations across a broad spectrum of frequencies.

Secondly, these accelerometer single sensors are made from stainless providing true durability allowing the sensor to operate in conditions from -40 to +121°C.
