Installation; Standard Stud Mount Procedure - PCB Piezotronics IMI SENSORS 640A10 Installation And Operating Manual

Installation

When choosing a mounting method, consider closely the advantages and disadvantages of each technique.
Typical mounting types are stud, direct adhesive, adhesive mounting base and magnetic mounting base. Since
the frequency response is limited to 1 kHz on the 640/641, any of the four methods can be used without seriously
affecting the data values. The mounting method might affect some of the 645/646 series because of the
increased frequency response.

Standard Stud Mount Procedure

This mounting technique requires smooth, flat contact surfaces for proper operation and is recommended for
permanent and/or secure installations. Stud mounting is also recommended when testing at high frequencies.
Note: Do NOT attempt mounting on curved, rough or uneven surfaces, as the potential for misalignment and
limited contact surface may significantly reduce the sensor's upper operating frequency range.
