OM-CP-BRIDGE120-25 high
speed data logger shown
larger than actual size.

The OM-CP-BRIDGE120 Series are
battery-powered, stand-alone data
loggers that measure and record
voltage signals from strain gages,
load cells and other low level dc
sources. These compact units are
perfect for monitoring stress, torque,
strain, pressure and data from many
other sensors/transducers.

OM-CP-BRIDGE120 Series data
loggers are available in ranges from
±10 to ±1000 mV, and are capable
of storing up to 32,767 readings,
and up to 20 readings/sec.

The OM-CP-BRIDGE units feature
non-volatile solid-state memory, and
can store readings even when the
battery is discharged.

Data retrieval is quick and easy –
simply plug into an available USB
port. The OM-CP-IFC software
displays your data in an easy to use
graph, so you can analyze your data
quickly.

A variety of powerful tools allow
you to examine, export and print
professional looking data with just
a click of the mouse.
