191 : Mounting Stud (Top Exit Sensors)

General  Characteristics (metric): 

• AISI 303
• -260°C to 700 °C (-436°F to 1292°F) (options dependant)
• Large choice of options for material and thread
• For top connector accelerometer Model 101 and 105

This is the most usual method for accelerometer mounting. These studs are detacheable, permiting rapid, low cost replacement. They are used by most accelerometer manufacturers but they are not fully compatible due to the sensor shoulder diameter and the thread length . You should not use ordinary machine screw because they lack a flange or shoulder and might bottom in the accelerometer and degrades his dynamic response. Stud mounting is considered as the most reliable way to mount a vibration sensor. Stud mounting will attain the maximum sensor frequency range. Stud mountind requires a tapped hole drilled directly into the structure. The sensor requires a flat spot faced surface with a perpendicular tapped hole.
