Description
The VIP Sensors Model 2011A is a stud mounted piezoelectric
accelerometer designed for general vibration measurement on
structures and objects. It features a high signal-to-noise ratio, a
high output sensitivity, and a wide bandwidth. The accelerometer
transmits its low impedance voltage output through the same
cable that supplies the constant current power.
The Model 2011A design is a welded stainless steel construction
that is hermetically sealed against external contamination. Signal
ground is connected to the outer case of the unit. When used with
an isolated mounting stud, the accelerometer is electrically
isolated from ground. The accelerometer features a 10-32 top
connector that is used with coaxial cable for error-free operation.
VIP Sensors Signal Conditioner Models 5005, 5100 and 5102 are
recommended for use with this low impedance accelerometer.

NOTES
1. Short duration shock pulses, such as those generated
by metal-to-metal impacts, may excite transducer
resonance and cause linearity errors.
