Acceleration

Annular Ceramic Shear Sensor

Light Weight, Voltage Mode, Triaxial Accelerometer

Type 8762A...

High sensitivity triaxial accelerometers that simultaneously mea-

sure vibration in three, mutually perpendicular axis (x, y and z).

Designed primarily for modal analysis applications, the triaxial

accelerometer features three tapped mounting surfaces that

allow each axis to be hard mounted for calibration.

Low impedance voltage mode

•

Cube shaped, ceramic shear sensor

•

Ultra low thermal transient response

•

Durable hard anodized, ground isolated aluminium housing

•

Conforming to CE

Description

Internal of the 8762A… accelerometer is a unique annular, shear

sensor element that features extremely low thermal transient

response, a high immunity to base strain and transverse accelera-

tion. An advanced hybrid charge amplifier design provides out-

standing phase response as well as a wide operating frequency

range. The light weight aluminum housing is epoxy sealed and

hard anodized coated to provide ground isolation.

Each of the three sensing elements is internally connected to a

microelectronic circuit that converts the charge from the ceramic

piezoelectric elements into a useable high level voltage signal at

a low impedance output. The 8762A… accelerometer series will

operate directly from the internal power source found in most

FFT analyzers; from several Kistler Piezotron® power supply coup-

lers or any industry standard IEPE (Integrated Electronic Piezo-

Electric) compatible power source.

Application

The lightweight 8762A… triaxial accelerometer series, is highly

desirable for measurement applications on light weight structures

where mass loading must be kept to a minimum. The accelerom-

eters are highly suited for multi-channel measurements; modal

analysis measurements on automotive bodies and aircraft struc-

tures; general vibration measurements.

Accessing TEDS Data

Accelerometers with a "T" suffix are variants of the standard

version incorporating the "Smart Sensor" design. Viewing an

accelerometer’s data sheet requires an Interface/Coupler such as

Kistler’s Type 5134B… or 5000M04 with TEDS Editor software.

The Interface provides negative current excitation (reverse po-

larity) altering the operating mode of the PiezoSmart® sensor

allowing the program editor software to read or add information

contained in the memory chip.

Mounting

The 8762A… accelerometer series can be attached to the test

surface by using a 10-32 stud inserted in any one of the three

threaded mounting holes. Reliable and accurate measurements

require that the mounting surface be clean and flat. The instruc-

tion manual for the 8762A… (8762A_002-233) provides detailed

information regarding mounting surface preparation.
