Description
The 4-161 series velometer is intended to
satisfy the general specification requirements
for a low cost vibration transducer. Designed for
use in multi-point experimental or light industrial
vibration monitoring applications, where velocity
measurements are required.
The two-wire current loop operating principle
permits very long interconnecting cables to
be used where neccessary and at minimum
expense since standard screened pair (or multipair) cables may be used.
The piezoelectric sensor and amplifier are
contained within an inner metal enclosure which
is electrically and thermally insulated from the
outer stainless steel body.
This arrangement prevents ground loops
and minimizes the effects of thermal shocks and
base strain. The inner enclosure is connected to
the 0V of the two-wire system and is therefore an
effective electrical screen. External connections
are made via a top exit integral cable or electrical
connector.
The transducer is mounted by means of a
single threaded hole in the base of the cylindrical
body, this being intended to accept a mounting
stud of the standard (non-isolating) type.
