Gauging sensor with plunger guided in
plain bearings and fitted with return spring.
The measuring probe is mounted via a
standard M2.5 thread and can be
interchanged with commercially available
measurement probes. Measurement
probes are primarily used for the
measurement and inspection of work-piece
geometry (length, width, diameter,
thickness, depth, height, etc.).

MSC710
sensor controller for LVDT series
Excellent linearity and resolution
Zero and gain adjustable coarse/fine
Excitation frequency 1 ... 10 kHz
(selectable)
Compact and robust EMI-proofed
housing
The MSC710 is a single-channel miniature
sensor controller for the operation of
inductive displacement sensors based on
the LVDT principle (Linear Variable
Differential Transformer). Its compact, but
rugged design, makes it suitable for both
industrial and laboratory applications.
Easily accessible and simple to operate, by
using DIP-switches. The electronic unit can
be matched to a wide range of sensors.
