Model 2228C
Piezoelectric accelerometer
Features
Description
• NEW! 2228C-R available as replacement sensor
• Triaxial
• Ground isolated
• Light weight (15 gm)
• Requires no external power
• Vibration measurement in three orthogonal axis
The Endevco® model 2228C is a small triaxial
piezoelectric accelerometer designed specifically for
vibration measurement in three orthogonal axes on
small structures and objects. The transducer features
three 10-32 receptacles for output connection and can
be screw or adhesively mounted. Its light weight (15 gm)
effectively minimizes mass loading. The accelerometer is
a self-generating device that requires no external power
source for operation.
The model 2228C features Endevco’s Piezite® type P-8
crystal elements operating in annular shear mode.
This unit exhibits excellent output sensitivity stability
over time. Signal ground is isolated from the mounting
surface of the unit. Low-noise, flexible coaxial cables are
supplied for error-free operation.
Endevco signal conditioner models 133, 2771C, 2775B, 6634C or OASIS 2000
computer-controlled system 4990A-X are recommended for use with this high
impedance accelerometer.
