Magnetic length and angle measuring system MPI-15
1. Safety instruction
The product has been developed and built in accordance with the
recognized rules of technology. The units have left the manufacturing
plant ready to operate and in safe condition.
To keep the units in this condition, it is necessary that the units are
installed and operated properly, in a safety and hazard-conscious
manner, under observance of this operating manual and in particular
of the following safety precautions.
Make sure that the personnel has read and understood the operating
manual and in particular the "Safety Instructions" chapter.
In addition to the operating manual, the generally applicable legal and
other binding regulations for accident prevention and environmental
protection must be observed and ensured.
This manual is intended as a supplement to already existing
documentation (catalogues, data sheets and assembly instructions).

Proper use

The units may only be operated:
- in the properly installed state and
- in accordance with the specifications of the technical data.
Operation not covered by the specified descriptions/parame-
ters, in conjunction with the systems/machines/processes to
be controlled/monitored, is improper and can lead to:
- fatal injuries,
- serious damage to health,
- property damage or
- damage to the units
As a result of a failure/malfunction or incorrect operation of
the units,
- a life-threatening danger,
- health risks or
- a danger of property or environmental damage
could result, if the units are used to control/monitor machines or
processes. Then appropriate safety precautions must be taken.

ELESA models all rights reserved in accordance with the law. Always mention the source when reproducing our drawings.
Do not open the housing of the units or make any changes to it.
Tampering with the units can have a negative effect on their operating
safety, causing danger. Do not make repairs on the units. Return
defective units to the manufacturer.
The correct behaviour of the MPI-15 is assured when the device
is used in combination with the magnetic band M-BAND-10.
The manufacturer is not responsible for possible malfunctions caused
by the use of a different magnetic band.

2. System description

The MPI-15, made of a LCD multifunction display with integrated
position sensor, combined with the magnetic band M-BAND-10, is a
complete system for the measurement of linear and angular displa-
cement. Characterised by extremely easy assembly, it allows precise
alignment and positioning, reducing times and machining procedures
to a minimum.
- Multifunction LCD with 5 function keys.
- Absolute/ incremental mode.
- Programmable offset function.
- External battery power supply 1.5 VDC.
- Buffered memory during battery substitution.
- Accidental polarity inversion protection.
- Magnetic sensor envelope material: anodized aluminium.

(1) Resolution: the smallest change in length that
the system is capable of displaying.
(2) Precision: the maximum deviation of the value measured
by the system from the actual one.
(3) Repeat accuracy: the degree of closeness between a
series of measures of the same sample, when the single
measurements are carried out leaving the measurement
conditions unchanged.
