What is cable mounting?
Cable mounts, also known as Primary Support Modules (instrument supports), utilize adjustable, high-strength cables to clamp instrument assemblies to process lines 3" through 36" in diameter. These Primary Modules can be used independently or together with Secondary Modules to construct a universal support package for any instrument in any position.
Mounting Techniques
Four main methods are used for attaching sensors to monitoring locations in predictive maintenance. They are stud mounted, adhesive mounted, magnetically mounted and the use of probe tips, or stingers. Each method effects the high frequency response of the accelerometer. Stud mounting provides the widest frequency response and the most secure and reliable attachment. Figure 5 shows ideal surface preparation for stud mounting sensors.
When choosing a mounting method, both the advantages and disadvantages of each technique should be closely considered. Characteristics such as location, ruggedness, amplitude range, accessibility, temperature and portability may be extremely critical. However, often times the most important and overlooked consideration is the affect the mounting technique will have on the high frequency operating range of the accelerometer.
Shown below are six possible mounting techniques and their affect on the response of a typical piezoelectric accelerometer. (Note that not all of the mounting methods may apply to your particular sensor.) By examining the mounting configurations and corresponding graph, it can be seen that the high frequency response of the accelerometer may be compromised as mass is added to the system and/or the mounting stiffness is reduced.
