Bruel & Kjaer 4815 Vibration Exciter Calibration Head

Description: Bruel & Kjaer 4815 Calibration Vibration Exciter Head Comes with what you see in the pictures. If you don't see it, you probably wont get it. Specifications are from Bruel & Kjaer and may vary slightly due to upgrades, options, or revisions this unit may or may not have. This unit is guaranteed to work. This is the head only (it does NOT include the body). The Unit's Serial Number Tag Reads: Model Number: 4815 Serial Number: 737966 Current Limit: 20 amperes rms Displacement Limit: 0.50" (12.7 mm) Head Constant: 2.7"/volt sec Bolt Torque Limit: 15 in-lbs (0.18 kgm) Applications: Environmental testing of objects and structures Resonance searching Fatigue testing of specimens Study of dynamic properties of structures and structural models Description: Calibration Head Type 4815 is primarily intended for the high acceleration calibration of accelerometers and other measurement transducers. A reference accelerometer is built-in for comparison purposes. Accurate transducer calibration is possible at levels up to 100 g in the frequency range from 5 Hz to 10 kHz; this allows calibration of most accelerometers at levels of normal operation. The reference accelerometer is ssituated directly under the mounting point of the test transducer to ensure the closest coupling. A short, very stiff, ribbed structure couples the drive coil to the mounting surface ensuring minimal distortion. The 12 element suspenstion system maintains a virtually rectilinear motion and minimizes transverse motion. Both axial and transverse resonances are highly damped by a layer of elastomer in a flexure sandwich.
