ACCELEROMETER MOUNTINGS PDF
An accelerometer is a sensor that senses the dynamic motion of the surface that it is attached to by producing an electrical output which is. The mounting of a vibration sensor (accelerometer) directly impacts on its performance. Incorrect mounting may give readings that relate not only to a change in. Accelerometer Mounting Techniques are described as far as Mounting Surface Preparation, Installation and a variety of methods.

However, dual-rail magnets can significantly decrease the operational frequency range of an accelerometer. Accelerometer Mounting Choosing the optimum mounting arrangement will significantly improve the accuracy.
Types of Accelerometer Mounting
UA Small swivel base set of Adhesive attachment using cyanoacrylate, epoxy glue or dental cement. A best practice is to attach the magnetic base to your test structure first, and then screw the accelerometer onto the magnetic base.
This mounting method provides a very secure attachment for the accelerometer to the test structure and matches the mounting configuration during factory calibration. Mounting an Accelerometer The sensor must be mounted directly to the machine surface to correctly measure the vibrations.
After the debonding agent has set, an ordinary open-end wrench can be used for removal for accelerometers with a hex base or square base. Small High-temperature Clip, insulated set of 5. Removable studs are favoured as they can be easily replaced when worn out. For applications where drilling is not allowed or possible.
Set of plastic clips for mounting directly on object surface. Industrial Grade Accelerometer Industrial grade accelerometers are the workhorses of industry.

Magnetic Mounting Magnetic Mounting attaches accelerometers to ferromagnetic surfaces and gives the users an advantage in that the accelerometer can be moved quickly from place to place. This type of accelerometer is commonly used in industry. Make sure that the mounting stud is not too long resulting in a gap between sensor and test object.
If not available, weld or epoxy a steel mounting pad to the test surface. UA Set of plastic clips for mounting directly on object surface. The magnetic acceleometer should be zccelerometer to a smooth, flat surface for best results. Types of Accelerometer Mounting admin T Stud mounting with stud boltinsulating flange or adhesive pad Magnetic base Adhesive by bee waxcyanoacrylate e. Modelsand provide isolation against ground loops.
Triaxial mounting cubes M3 M5 M8 M10 For triaxial measurements with three uniaxial accelerometers Handle adapter For the attachment of accelerometers with M3 thread on curved surfaces Accelerometer probe M5 For estimating and trending measurements above 5 Hz and below Mounfings. Approximate frequency ranges of mounting techniques.
Laboratory Accelerometer for High Vibration Levels. As such, correct mounting of a vibration sensor is vital to ensure true readings. This can be accomplished by several types of mounts: Their L Stainless steel case is hermetically sealed against the environment so they can survive harsh industrial environments. When the situation arises that the stud mount method is impractical or impossible, adhesive mounting is the recommended method.
The output level will be proportional to the accellerometer of the vibrations. Install the accelerometer making certain that the stud does not bottom out in the mounting surface or the accelerometer base. Adhesively mounted accelerometer To avoid damaging a sensor during the removal process, a debonding agent must be applied to the adhesive.
Acceleration is transmitted from the structure surface into the accelerometer base. Insert the cap screw into a through-hole in the accelerometer housing and screw it into a tapped hole on the mounting surface see Mountinsg 3A.
Temperature Sensitivity is the voltage output per degree of measured temperature. Misalignment of the sensor axis and the measuring directions should be kept as low as possible, particularly if transverse vibration of high magnitude occurs. To detect any faults in machine components, vibration sensors should be mounted in locations that ensure horizontal, vertical and axial movement are measured effectively: The mounting of a vibration sensor accelerometer directly impacts on its performance.

Ferromagnetic object with smooth and flat surface required. The must be no gap under the sensor. Get updates on exclusive content. Resonance Frequency is the frequency at which the sensor resonates or rings.
