UltraShock
The MadgeTech UltraShock is a 3-axis shock / acceleration data logger with additional channels for temperature, humidity
and barometric pressure. Each of the six channels may be made active or inactive as needed. Disabling channels will
provide additional storage to the enabled channels.
The UltraShock is specifically designed for documenting dynamic environments such as moving vehicles, trucks,
containers, ships, etc. The device is also valuable in characterizing environments such as production and assembly lines of
delicate electronics, IC fabrication, communications and computer components.
The UltraShock contains two separate accelerometers to provide high sensitivity and accuracy up to 15g or higher levels
of shock monitoring up to 300g. One of three operating ranges must be chosen during setup for a logging session. Those
ranges are +/- 15g (low g accelerometer), +/- 100g and +/- 300g (high g accelerometer).
Physical Mounting
The most accurate transfer of shock, vibration and acceleration to the
final logged data will occur when the mounting is mechanically rigid.
Typically, this would occur when the UltraShock is mounted by two bolts
directly to a solid metal, flat surfaced object of significant mass.
For various applications, the rigid “bolted down” mounting may not be
optimal or practical. The bottom surface of the UltraShock is precision
machined flat. It is possible to mount the unit by the use of a double-
sided adhesive material. MadgeTech does not make recommendations
of specific materials but several points to consider are:
• Adhesive joint should be as thin as possible
• Adhesive joint must have adequate strength to support the unit under conditions expected in use (temperature,
shock, vibration, etc.)
• Adhesive joint material should be as stiff as possible (high durometer)
The stiffness of the mounting material will affect the transfer of shock or vibration to the UltraShock. A soft material will
have a tendency to reduce the transfer of high frequencies while a hard material would, in varying degrees, come closer to
the fidelity of signal that a bolted down mount would provide.
Orientation of Axes
The illustration to the right shows the directions of the x, y and z
axes. They are also laser engraved on the front face of the unit.
If an UltraShock is positioned so that any axis points upward,
that axis will report a g force of +1 g.
