Adhesive Accelerometer Mounting Bases

In order to have a fairly rigid (stiff connection) between the sensor and the test object it is mounted onto, an Adhesive Mounting Base (when glued or epoxied) provides the proper stiffness required to get the highest frequency response possible for a given accelerometer. An adhesive wax mounting reduces the upper frequency response. Adhesive accelerometer mounting bases are utilized to facilitate adhesively mounting an accelerometer to a test surface. The base is secured to the test object with a suitable adhesive such as epoxy, glue or wax. The accelerometer is then stud mounted to the other side of the adhesive mounting base and properly torqued to specification. The use of the adhesive mounting base prevents the adhesive from being in direct contact with the sensor and potentially clogging the sensor tapped mounting hole. Accelerometers may be easily moved to multiple bases installed at various locations. All bases are machined of lightweight aluminum with a grooved side for applying the adhesive and a hardcoat finish side which provides electrical isolation between the test object and the accelerometer. This electrical isolation is a good method to help reduce or prevent the feared “Ground Loop”. For proper mounting, match the hex size on the accelerometer to the hex size on the adhesive base. Use the next larger adhesive base hex size if a match is not available.
