Standard Stud Mount This mounting technique requires smooth, flat contact surfaces for proper operation and is recommended for permanent and/or secure installations. Stud mounting is also recommended when testing at high frequencies. Note: Do NOT attempt mounting on curved, rough or uneven surfaces as the potential for misalignment and limited contact surface may significantly reduce the sensor's upper operating frequency range. STEP 1: First, prepare a smooth, flat mounting surface, and then drill and tap a mounting hole in the center of this area as shown below. A precision machined mounting surface with a minimum finish of 63 ΅in (0,00016 mm) is recommended. (If it is not possible to properly prepare the machine surface, consider adhesive mounting as a possible alternative.) Be certain to inspect the area checking that there are no burrs or other foreign particles interfering with the contact surface. STEP 2: Wipe clean the mounting surface and spread on a light film of grease, oil or similar coupling fluid prior to installation. Adding a coupling fluid improves vibration transmissibility by filling small voids in the mounting surface. This consequently increases the mounting stiffness. For permanent mounting, substitute epoxy or other type of adhesive. STEP 3: Hand tighten the sensor/mounting stud to the machine and secure the device by applying the recommended mounting torque. It is important to use a torque wrench during this step as undertorquing the sensor may not adequately couple the device, while overtorquing may result in stud failure.
