The ST133 Series inductive displacement sensors using the LVDT principle
(Linear Variable Differential Transformer) consist of a primary and two
secondary coils with a common movable magnetic core. An oscillator
electronics excites the primary coil with an alternating current of constant frequency.
Consequently alternating currents are induced in both secondary coils with
amplitudes depending on the core position. A displacement of the core
yields a higher voltage in one secondary coil and a lower voltage in the other
coil. The difference between both secondary voltages is proportional to
the displacement. This simple principle along with their robust design makes these sensors ideal
for a wide variety of industrial measurement applications.
Selections
 | ST133-D Series: The ST133-D displacement model sensors work with a free moving
plunger without any mechanical contact to the sensor body. The
plunger is fixed onto the target by a mounting thread. The
measuring principle within the sensor is without contact and thus
wear-free. Waterproof housing (welded/sealed up to 5 bars) option
is available. |
| ST133-G Series: The ST133-G Gauging model sensors are equipped with a
plunger sliding in a plain bearing. The probe is pushed against
the target surface by means of a spring. The probe is mounted onto
the plunger via a standard M2.5 thread. It can be easily exchanged
with any other probe tip model. |
