Safe parallel
guidance by integrated position
sensor with velocity output.
In mobile hydraulics
applications, sensors are subject to a cluster of marginal conditions.
For this reason, a development focus is on the integration of
measurement systems into hydraulic cylinders.
Furthermore,
in special applications where mobile machines control an overall
movement by means of several cylinders, synchronization of movements
is required.
Therefore,
the Temposonics M series are especially made for integration
into hydraulic cylinders. The sensor is protected against shock,
vibration and extreme environmental conditions and offers an
unrivalled measurement rate, outstanding repeatability (>
+/- 0.005%) and stable linearity (> 0.04%). External effects
on the measurement signal are virtually excluded by interference
suppression for HF electric fields up to 200 V/m, vibration resistance
up to 30g(av) and shock resistance of more than 100g. Magnetostrictive
Temposonics MH sensors also offer continuous measurement of both
- position and speed - during the position change.
Due to the output of a velocity signal, highly dynamic control
of several independent hydraulic cylinders is possible. It enables
the power actuators to be developed into complex movement axes
and permits realization of high-quality control systems, e.g.
for electro hydraulic parallel guidance of excavators or loaders.
