Displacement sensors with external electronics
induSENSOR LVDT
- Proven LVDT technology
- Measuring ranges ±1 … ±25mm
- Extremely accurate also under
difficult ambient conditions
- Long-term stability
- Wear-free
LVDT displacement sensors have a plunger
which moves freely in the sensor housing.
The plunger is joined to the object by a thread
to transfer the movement of the measurement
object. The measurement process in the sensor takes place without contact and is therefore wear-free. The displacement sensors are
mainly used to measure and monitor movements, displacements, positions, strokes, deflections, dislocations, etc. in vehicles, machines and systems.
The high sensor resolution is limited only by
the noise in the sensor electronics. A further
advantage of the symmetrically constructed
sensors in the LVDT series is the zeropoint
stability of the systems. The sensors are supplied with an excitation frequency of 1 to 5 kHz
depending on the measurement range and an
excitation amplitude of 2.5 to 5Veff. Matched
sensor electronics are available in this respect. With appropriate setting possibilities for
the excitation frequency and amplitude, the
sensors can also be operated with alternative
electronics.

Sensor controller for LVDT series
induSENSOR LVDT
- Excellent linearity and resolution
- Zero and gain adjustable coarse/fine
- Excitation frequency 1 ... 10kHz
(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.
