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.
