A variety of IEPE accelerometers are available from Durham Instruments. These devices are used in many applications to measure the acceleration of a mass, specifically sensing larger vibrations and shocks.
IEPE accelerometer basics
IEPE stands for Internal Electronics PiezoElectric. IEPE accelerometers use piezoelectric material to measure proper acceleration (also known as g-force acceleration). They incorporate electronics that act as a “pre-amplifier” to transform the piezoelectric signal to a low impedance signal.
The type of acceleration measured by accelerometers is quite different from the co-ordinate acceleration that is familiar to most people. Proper acceleration is the acceleration of a mass associated with its weight at rest in the frame of reference of the accelerometer.
Durham Instruments can offer many different models of accelerometers. Its lineup of IEPE accelerometers includes:
- The 7130A model is a triaxial IEPE accelerometer. The unit utilizes three independent welded stainless steel assemblies in a housing made from hard anodized aluminum. It incorporates a stable piezoceramic crystal in annular shear mode. The crystal is installed with a compression ring that eliminates the need for epoxies that can hinder long-term stability. The 7130A is available in ±50g to ±500g dynamic ranges. This model is used in manufacturing, as well as research and development applications.
- The 7114A is an IEPE accelerometer that offers high performance. It is stud mounted and has a side mount connector. In addition, the unit has a hermetically sealed enclosure and features high sensitivity of 1,000 mV/g. It is available in dynamic ranges from ±5g to ±50g. This unit is used in many industries, including aerospace, military, automation and controls, transportation and more.
These accelerometers are made by Measurement Specialties, an international manufacturer of sensors and sensor-based systems. The company is dedicated to providing products that are effective, reliable and high quality.
