Triaxial accelerometer designed for high-precision vibration measurements

Paul Boughton

Meggitt Sensing Systems, a Meggitt group division, has announced the new product launch of the Endevco model 35A, said to be the world’s smallest ISOTRON (IEPE-type) triaxial accelerometer with integral electronics, designed for high-precision vibration measurements in three orthogonal axes on very small objects.
Offering a low impedance output, shear mode construction and weighing just 1.1 grammes without cable, the adhesive mounted Endevco model 35A is designed as a complete measurement package to reduce the unwanted effects of mass loading on more delicate test structures.

Sensor output is transmitted through the same wires that supply required 4 mA constant-current power.

The model comes pre-installed with both field repairable and factory replaceable fine gage wires (34 AWG) as output leads.  Model 35A includes the Endevco model 3027AM5-120 cable with pigtails at one end to connect to the pre-installed accelerometer wires and three BNC connectors at the other end.  A removal tool is also provided.

With its extremely small size, the Endevco model 35A is suitable for the shock and vibration testing of electronic components and equipment; automotive component vibration monitoring; scale model vibration testing; and biomedical research.
