FIRST MEASURING TAPPET
It is not always possible to determine the position of objects
without contact. This may be due to the object material or
other material properties. In such applications, only tactile
solutions can be used and this is exactly what the YM120020
spring-loaded measuring tappet from ipf electronic is suitable
for.
The YM120020 with M12 external thread has a travel range of
-5 to +5mm with a maximum linearity deviation of ±0.5% over
the entire measuring range. The position of the plunger with
hardened probe tip is output as an absolute analog signal (0-
10V) via an M12-connector.
The sensor works according to the differential transformer
principle. The spring-mounted measuring rod also serves as the moving core of the excitation coil. A passive coil is positioned to
the left and right of this coil. As soon as the rod is no longer in
the middle 0mm position, a voltage is induced in one of the two
neighboring coils and enables the displacement measurement
by means of downstream electronics. This high-resolution and
wear-free design achieves a high level of mechanical robustness
with a shock resistance of 200g, 2ms. This functional principle
also ensures that the measured value is retained after a voltage
interruption.
Areas of application for the new plunger can be found across
all industries in automation as well as process and quality
assurance under harsh environmental conditions, such as wet
conditions, aggressive chemicals or high ambient temperatures.
