13 Glossary
Detection range The detection range describes the maximum physical range in
which the sensor can determine a position. The detection range is
max. +30 mm and - 30 mm around the physical zero position.
Dynamic Pilot Dynamic Pilot sets an additional condition for the switching process
during operation:
In addition to the condition that the magnet must be located
within the tolerance band defined in
Dynamic Teach , the speed of
the magnet must also be v = 0 in order to switch on.
•
1. Qint switches on ...
... when a magnet moves into the tolerance band and v = 0 for
the first time within this tolerance band.
• 2. After switching on, Qint remains on ...
... as long as the magnet is within the tolerance band and the
hysteresis (depending on whether v = 0 or v ≠ 0).
• 3. Qint switches off ...
... as soon as the magnet leaves the hysteresis.
Dynamic Teach and Man‐
ual Teach Dynamic Teach and Manual Teach are two different teach options. The
teach-in button can be used to execute both Dynamic Teach and
Manual Teach .
• Dynamic Teach :
Dynamic Teach can be used to have the sensor automatically set
the end points of the desired measuring range.
• Manual Teach :
Manual Teach is used to manually teach in the two end points of
the measuring range using the teach-in button. Both end
points are taught in separately.
The teach-in processes are described in detail in chapter 8.3 .
Linearity error The linearity error describes the maximum deviation of the output
signal from an ideal straight line. It is measured in millimeters.
MPS-G with analog output: The linearity error depends on the
drive on which the sensor is mounted and is typically 0.3 mm.
Measuring range The measuring range can be anywhere inside the detection range.
The measuring range must always be completely inside the detec‐
tion range.
Out-of-Range display The Out-of-Range display is used to display the analog position out‐
put when the magnet has left the measuring range. If 11 V is out‐
put, the magnet has left the measuring range in the positive direc‐
tion (on the side of the sensor fixing screw). If 10.5 V is output, the
magnet has left the measuring range in the negative direction (on
the cable side of the sensor).
Range of movement The range of movement describes the actual path traveled by the
piston.
Repeatability Repeatability is defined as any move to a preset position from the
same direction in every case.
MPS-G with analog output: The repeatability depends on the drive
on which the sensor is mounted and is typically 0.05 mm.
Resolution The sensor resolution describes the minimum, specifiable magnet
route change as output by the sensor.
MPS-G with analog output: The resolution depends on the drive on
which the sensor is mounted and is typically ≥ 0.01 mm.
