Seismic Transducer Mounting Systems
Description
The Quick-Set and Mag-Force mounting systems provide an alternative method
for mounting the following seismic transducers:
138648-01 Quick-Set
139153-01 MAG-Force
•
200150 Accelerometer
•
190520 Accelerometer
•
190501 Velomitor® CT
Either mounting system can be ordered as part of these transducers by
specifying the appropriate mounting stud option. They are easier to implement
than conventional stud mounting, and are stronger than most adhesive studs.
Note: These mounting systems are suitable only when it is not necessary to
measure frequencies above 2kHz.
The Quick-Set system uses a low torque, self-tapping screw that can be screwed
into a #26 pilot hole drilled in the machine casing. It also has a 3/8-in 24 stud to
attach the transducer. This is usually easier to accomplish than drilling and
tapping the machine to accept a threaded stud.
The Mag-Force system uses a powerful magnet in conjunction with a durable
industrial strength adhesive. The combination of the magnet and adhesive
provides a more durable installation than either one alone. Since it is not
necessary to drill a hole in the machine, the costs associated with system
documentation may be less than when the machine is drilled and tapped.
