The PRETEC series 2900 half bridge electronic transducers have been designed to make them compatible with most brands of comparators, by a switchable bridge in the connector. All models are furnished with hard-chrome plated 8mm dia. shaft, a 2.5mm dia. carbide contact point with a 2.5mm thread. A variety of carbide, ruby, flat, chisel and roller contact points are available.
There is no valid specification
for the electrical values of inductive probes. This is one of the reasons why
they are normally not exchangeable.
In order to avoid disadvantages in
case of replacement or delivery delays, all PRETEC probes can easily be adapted
to many electronic measuring instruments in the market (i.e. Tesa, Hommel, Metem
a.s.o.) by means of a switchable bridge inside the connector.
The
construction is based on our long experience in probe manufacturing. Even under
rough conditions the probe guarantees a good repeatability of the measurement.
The body of the standard probe O 8-h6 x 80 mm) is carbide chromed and ball
bearing guided. An additional roller bearing locks the probe head against
distortion. The pre-travel and the post-travel can be set continuously
.
