Accelerometer ACH-01

Accelerometer ACH-01
Piezoelectric Accelerometer
Wide Bandwidth; AC Coupled
Ultra Low Power
High G Ranges
The ACH-01 is an inexpensive, general
purpose accelerometer with outstanding
performance characteristics. The use of
piezoelectric polymer film in the ACH-01
provides many cost/performance advantages
that allow it to be used in a wide range of
applications where the use of traditional
accelerometer technology is impractical. It is
specifically designed for high volume
applications which require the permanent
installation of an accelerometer.

Performance
mounting requirements
Specifications
Mounting methods play a critical role in determining the overall performance of any
accelerometer. The ACH-01 is no exception. An improperly mounted accelerometer
can give erroneous results. We recommend using an Adhesive Mounting Method.
The surface should be flat. The area where the ACH-01 is to be mounted should be
thoroughly cleaned to remove any dirt or oil present on the surface. Use a quick
setting, viscous methyl cyanoacrylate adhesive such as Loctite's Black MaxJ or any
epoxy such as Devcon's 5-Minute epoxy. Apply the adhesive sparingly to one
surface following the manufacturer's directions. Apply pressure and allow the
adhesive to set. Soft adhesives, such as double-sided tape or pressure sensitive
adhesives, should not be used since they can adversely affect the ACH-01's
performance. Cable should be adhered to the surface.
There is an interface amplifier available to simplify connection to the ACH-01, the IBACH-01. Please see the appropiate data sheet.
In an effort to keep the product cost low, the ACH-01 uses a ceramic substrate as the
mounting base. Because of this, the ACH-01 is susceptible to base strain and
temperature transient effects. A mechanically rigid and thermally non-conductive
mounting surface is highly recommended to limit these effects. MEAS application
engineers are available to recommend various mounting arrangements for your
specific application.
