Description

The dynamometer consists of four, 3-component force sensors which are mounted under high pretension between the cover plate and the four lateral assembly elements. Thanks to this special mounting of the sensors, temperature influences can be partially compensated for and the influence of the temperature thereby minimized. The force measurement of the sensors is based on the piezoelectric principle. The application of a force causes the crystal rings installed in the sensor (one crystal ring for each of the force components that is to be measured) to release a charge that is proportional to this force. The charge signals of the four installed force sensors are internally connected and output by a 9-pin flange socket. In addition to the direct measurement of the three force components, an indirect measurement of the torque Mz is possible through an appropriate calculation. The sensors are mounted ground-isolated (dry state). Ground- loop problems can thereby be largely avoided. The dynamometer is corrosion resistant and protected against the penetration of cooling lubricant. Together with the 8-pin connecting cable Type 1677A5, Type 1677AQ02 or Type 1679A5, the dynamometer is protected against the penetration of dust and liquids according to degree of protection IP67. Application examples

MicroDyn – multicomponent dynamometer up to 500 N, cover plate 30x30 mm, Type 9109AA 9109AA_003-346e-08.18 Mounting The dynamometer can be mounted with eight M4 screws to any face-ground, clean mounting surface, such as on a machine tool table. Mounting on a magnetic plate is made possible by means of a supplied steel base plate. It must be noted that uneven contact surfaces may cause internal distortions, which could place additional heavy stresses on the individual links and increase crosstalk. M4 tapped blind holes, Ø3.4 through holes as well as 4.5H7 fittings are provided in the cover plate for mounting the force-introducing components such as workpieces or work holders. The contact surfaces of the force-introducing parts must be surface ground to achieve good mechanical coupling to the cover plate. Measuring signal processing The sensor outputs the charges of the individual sensors via a 9-pin connector with the following pin assignment. Pin no. Output signals Type 1677A/1679A Ground Fx' 1 Fx' 2 + 4 Fx' 3 Fy' 1 + 3 Fy' 2 Fy' 4 Fz' 1 + 2 + 3 + 4 NC To convert the charges output by the sensor to a voltage that can be used by data acquisition devices, multi-channel charge amplifiers are used (e.g., Type 5080A or Type 5167A81). The measurement value of the individual channels is proportional to the applied force. Data acquisition If a high-end laboratory charge amplifier Type 5080A is used, Kistler offers a universal and simple to operate package with DAQ system Type 5697A1 consisting of hardware for data acquisition as well as the DynoWare software. For details, see data sheet doc. no. 5697A_000-745. If charge amplifier Type 5167A81 is used, this is available as model Type 5167A81DK with digitalization and the Dynoware software in the package. This eliminates the need for other external data acquisition, thereby reducing wiring work considerably. Data analysis To calculate the three orthogonal force components and the torque Mz from the output signals, the following equations are used: Fig. 2: Mounting the dynamometer Type 9109AA Mounting on machine table Fig. 3: Mounting the dynamometer Type 9109AA Mounting with steel base plate on magnetic table System coordinates Outputs Fx = Fx1 + Fx2+4 + Fx3 = Fx'1 + Fx'2+4 - Fx'3 Fy = Fy2 + Fy1+3 + Fy4 = Fy'2 + Fy'1+3 - Fy'4 Mz = (-Fx1 - Fy2 + Fx3 + Fy4) · a · kMz = (-Fx'1 - Fy'2 - Fx'3 - Fy'4) · a · kMz When using the Dynoware software, these calculations rules are stored in a template, eliminating the need for additional programming when setting up the system and thereby avoid- ing errors.
