PY2

RECTILINEAR DISPLACEMENT TRANSDUCER
WITH BALL TIP

Principal characteristics

• The side connection creates a through-rod structure with
double rod support, guaranteeing greater overall strength
of the transducer.

• The return spring automatically returns the rod to zero
position, making the transducer suitable for comparator
applications.

• The tip with stainless steel ball is suitable for applications
where the object to be measured is not subject to shifts
transverse to the transducer axle.

• Ideal for checking the flatness or thickness of panels
of various materials. Can also be used for valves or
mechanical parts when the rod cannot be attached to the
moving object.

INSTALLATION INSTRUCTIONS

• Respect the indicated electrical connections (DO NOT
use the transducer as a variable resistance)

• When calibrating the transducer, be careful to set the
stroke so that the output does not drop below 1% or rise
beyond 99% of the supply voltage.
