SIGMA wedgemount transducers are similar in design and fabrication to
a contact transducer, in that it is a single element unit that generates
a shear or longitudinal wave into the part under inspection, by being
mounted on an angled wedge, which is normally of a lesser velocity.
These transducers will mount to any manufactured replaceable wedge,
which includes threaded or standard screw mounts.
transducers are available in frequencies from 0.5MHZ to 15MHz, and have
element diameters from 0.125 to 0.50 inches, have top mount miniture
connectors, (Lemo or Microdot), other connector locations available
by request. Wedgemount transducers with BNC connectors for standrd and
snail wedges are available with rectangular elements to .75x1.0 inch
and round elements with diameters to 1.0 inch

vespel - for surface temperatures to 450 degrees F, proportionately
higher by observing an appropriate duty cycle, and radiation resistance
greater than 108 RADS
Replaceable wedges are available for use in automated systems by addition
of couplant feed tubes, machined grooves in the contact face, and appropriate
