 Our
contact free data acquisition system uses wireless power
and data transmission to achieve accurate test results
from difficult measurement areas. These rugged,
miniaturized telemetry systems completely eliminate the
need for slip-rings and provide superior quality data
with extremely low noise - maintenance free.

Dual Channel
Telemetry System
The new MICRODAC B2 gets the data off rotating devices
and transmits it contact free with
excellent quality (FM-transmission), has modular
design, is flexibel and easy to
install.
The B2 is
ideal for measurement
of torque, strain or temperature
on axles, propellers, machine
tools, centrifuges, turbines, rigs
in diverse industries like
Automotive, Mechanical
Engineering, Test Beds, Marine,
Rail and Process Control.
