Accessories : all in a plastic case with foam cut outs
001 Probe : attach the accelerometer via the M5 thread, press onto the test object perpendicularly - for estimating and trending measurements above 5 Hz and below 1000 Hz.
002 Adhesive Wax : For quick mounting of light sensors at room temperature and low acceleration. Roll wax in fingers to soften, smear thinly on test surface and press transducer onto the wax - using the DB 0765 cement stud avoids wax blocking the accelerometer thread.
004 Cable Clamps : If screwed onto the test object together with the accelerometer, it avoids any force introduced via the cable into the transducer.
006 Insulating Flange : with M5 threads and 'spanner'. Avoids earth loop problems, not recommended above 100 °C.
008 Mounting Magnet : with M5 mounting thread, suitable for fixing to a magnetic object with a smooth surface. If not available weld or epoxy a steel mounting pad to the test surface. For the best high frequency result apply a thin layer of silicon grease between the surfaces.
017 Cable Adaptor : BNC / 10-32 UNF
050 Cable : with 10-32 UNF plugs - 1.5 m long, 80 °C.
DB 0765 Cement Stud : 10-32 UNF thread - 14 mm Ø - on sale or return
QA 0013 Hexagon Key : for tightening 10-32 UNF studs
YQ 2960 Mounting Stud : 10-32 UNF thread, 12 mm long. This is the best fixing method and for the best high frequency performance. Apply a thin layer of silicon grease between the sensor and the test surface. Recommended torque = 1 Nm.
