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.

The mass of the accelerometers should be significantly smaller than the mass of the system to be monitored. This provides the best high-frequency transmissibility. What is the size and shape of the sample to be monitored? This stiffness and strength allows these sensors to be directly inserted into machines as part of their structure.
The screw engagement length should always be checked to ensure that the screw does not bottom out into the accelerometer base. Use an insulated cap screw to securely mount a ring-style accelerometer.
Accelerometer
Teardrop accelerometer model C22 and supplied removal tool model A Adhesives, and threaded studs are considered permanent mountings. Use a low sensitivity accelerometer to measure high amplitude vibrations and conversely use a high sensitivity accelerometer to measure low amplitude vibrations. Stud mounting is recommended if the accelerometer has an integral stud or if it has a tapped hole and is supplied with a removable stud.
Ground Isolated accelerometers have the electrical components isolated from the case and are much less susceptible to ground induced noise.
Small swivel base set of Choose the right accelerometer. The stud mount method is the preferred method of mounting an accelerometer to the test object.
Large Calibration Clip for mounting accelerometers under calibration. Magnetic clamps M3, small M3, large M4 tap M5, large M5, small M8, small M8, large For rapid mounting with limited high frequency performance.
The accelerometer dynamic range should be broader than the expected vibration amplitude range of the sample. The addition of any mass to the accelerometer such as an adhesive or magnetic mounting base lowers the resonant frequency of the sensing system and may affect the accuracy and limits of the accelerometer usable frequency range.
Frequency Response is determined by the mass, the piezoelectric properties of the crystal, and the resonance acceoerometer of the case. New vibration switch protects critical assets 17th November When the situation arises that mkuntings stud mount method is impractical or impossible, adhesive mounting is the recommended method.
ACC A is hermetically sealed for harsh environments, has a fixed cable and weighs only 50 grams. Magnets with high pull strengths provide the best high-frequency response.
Typically specified in g’s.

For estimating kountings trending measurements above 5 Hz and below Hz. Cable clamps M5 M3 Avoid introduction of force via the cable into the transducer. Types of Accelerometer Mounting. Description 0 March 10, A thin layer of silicone grease at the mounting interface of either configuration ensures the best high-frequency transmissibility.
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 analogous to that motion. For adhesive mounting, some accelerometers are deigned to be mounted directly to the test surface while others require mounting adapters or bases for adhesive mounting.
Adhesive Mounting When the situation arises that the stud mount method is impractical or impossible, adhesive mounting is the recommended method. Accelerometer Introduction to Acceleration Measurement.
Typically the range is to C.
Guidelines for Mounting Test Accelerometers
Set of plastic clips with thick base that can be filed down to suit your mounting surface. Then, prepare a tapped hole in accordance with the supplied installation drawing. Accelerometer Mounting Choosing the optimum mounting arrangement will significantly improve the accuracy. Accelerometer Power Supplies, Battery Powered.
Accelerometer Mounting
UA Large High-temperature Clip, insulated set of 5. Modelsand provide isolation against ground loops.
For quick mounting of light sensors at room temperature and low acceleration. 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. For best performance, particularly at high frequencies, the accelerometer base and the test object should have clean, flat, smooth, unscratched and burr-free surfaces.
