Product Overview
The OM-CP-ULTRASHOCK-A 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 OM-CP-SHOCK300 is a 3-axis shock / acceleration data logger. Each of the three channels may be made
active or inactive as needed. Disabling channels will provide additional storage to the enabled channels.
The OM-CP-ULTRASHOCK-A and OM-CP-SHOCK300 are 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 OM-CP-ULTRASHOCK-A and OM-CP-SHOCK300 contain 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 OM-CP-
ULTRASHOCK-A and OM-CP-SHOCK300 are 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 OM-CP-ULTRASHOCK-A and OM-CP-SHOCK300 are precision machined flat. It is possible to
mount the unit by the use of a double-sided adhesive material. Omega 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)
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 OM-CP-
ULTRASHOCK-A and OM-CP-SHOCK300 are
positioned so that any axis points upward, that
axis will report a g force of +1 g.
