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.

ACCELEROMETER ACH-01
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 IB-ACH-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.
ELECTRICAL INTERFACE CIRCUITS
The accelerometer ACH-01 accommodates various electrical interface circuits. A typical example is provided in the
following figure. The ACH-01 equivalent electrical schematic is also shown.
