DISCLAIMER PN: 1004568-8 LOC ER 1.0 INTRODUCTION This specification covers the application requirements of Measurement Specialties Accelerometer ACH-01. 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, such as machine health monitoring, modal analysis, automotive sensors, appliances, and feedback control systems. Features of the accelerometer include: − Wide Frequency Response − Low Transverse Sensitivity − Excellent Phase Response − Wide Temperature Range − Wide Dynamic Range − Small Temperature Dependence − Low Cost − 3V to 40V Supply − Ultra-Low Power − Impedance Buffered Output − Very High Resonant Frequency − Excellent Linearity ACH-01 SERIAL # ACH-01-02 with Pins ACH-01-04 with Wires (GND) BLACK (OUT) WHITE (V+) RED (OUT) (GND) (V+) .025 SQUARE PINS .10 TYP.

An improperly mounted accelerometer can give erroneous results. For this reason, MSI Sensors recommends the following mounting method to insure the proper performance of the ACH-01: 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. See Instruction Sheet 408-9953. 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. MSI application engineers are available to recommend various mounting arrangements for your specific application. 3.2 Electrical Interface Circuits The accelerometer ACH-01 accommodates various electrical interface circuits. A typical example is provided in the following figure. Since the ACH-01 uses the same internal JFET as Measurement Specialties= ACH-04-08-05 Multiple-Axis Accelerometer (Part Number: 1003800-5), additional circuit ideas can be found by reviewing Application Specifications 114-27002 and 144-70025. The ACH-01 equivalent electrical schematic is also shown.
