Electronic Length Measuring
Brown & Sharpe/TESA offers a complete family of value sensors
(electronic probes) as well as dedicated measuring instruments
for the most demanding applications. Our standard probes – also
called half-bridge probes – are electronic and require no
All Brown & Sharpe/TESA electronic probes can either be used
with hand-held internal and external measuring instruments or in
conjunction with measuring stands and other typical measuring
devices. Brown & Sharpe offers axial probes with linear
displacement of the measuring bolt, angled probes with inclinable
lever, or probes with parallel guiding that are specially
designed for multi gaging devices and other equipment for
in-process inspection. These probes are primarily used for making
comparative measurements, based on a master standard, which is
typically a gage block or setting ring.
• Random errors are significantly reduced as display setting
and all subsequent measurements
are usually made under the same conditions.
• Brown & Sharpe measuring instruments are provided with
an analog and/or digital display depending on their type.
• Signal processing can be made with positive or negative
polarity signs. The use of one single probe enables single
measurements of internal or external dimensions while the use of
two probes produces either a sum measurement or a difference
• The ability to store values provides a level of security
while taking dynamic measurements. The smallest or highest value
as well as the difference between both values are examples
of the part features that are questioned when capturing form and
• Limit deviations are used to classify the measured values.
These provide notification when out of tolerance conditions
