Features and applications

MPI-R10-RF measuring system connected to a specific sensor FC-MPI, combined with the magnetic band M-BAND-10, is a complete system for the measurement of linear and angular displacement (with a minimum radius of 65 mm).

Characterised by an extremely easy assembly, it allows precise alignment and positioning, reducing time and machining procedures to the minimum.

  • Maximum ease of assembly and disassembly operations of the device from the panel, thanks to a system with retention wing (ELESA PATENT).
  • 7-digit LCD of 12 mm height and special characters.
  • Programmable with 4 multifuction keys.
  • Values displayed in millimeters, inches or angular degrees.
  • Display of absolute or incremental mode.
  • Up to 10 programmable offset values.
  • Storage and display of 32 target positions.
  • Long-life internal lithium battery.
  • Buffered memory during battery substitution.
  • Housing for FC-MPI connector with snap-in assembly system for easy insertion and removal.

(1) Reading speed affects battery life.

(2) Resolution: the smallest variation in length that the system is able to display.

(3) Accuracy: the maximum deviation of the value measured by the system with respect to the real value.

(4) Repeatability: the degree of closeness between a measurement series of the same sample, when the individual measurements are made, leaving the measurement conditions unchanged.

Quick positioning system

MPI-R10-RF measuring system is networked to the control unit UC-RF via radio frequency (RF), constituting a wireless system for the rapid positioning of machine parts or multi-axial measurements (fig.4).

The wireless connection allows:

  • reading of the current position
  • setting of the target position
  • configuration of all operational parameters

The radio frequency system network allows different machines to coexist in the same space without problems of mutual interference.

This system is particularly suitable for applications that require frequent format changes, facilitating the correct adjustment of the target/current position of the machine parts, also representing a safety system. In fact, even if a single MPI-R10 measuring system is not placed in the target position, PLC doesn’t allow the beginning of the machine production cycle, thus avoiding production issues.

The installation of the system is quick and easy as it does not require the use of connecting cables between the control unit and the indicators.

Accessories on request

Magnetic band M-BAND-10.

Special executions on request

Assembly instructions

  • Drill the sheet (thickness 0.7÷2 mm) according to the template dimensions.
  • Remove all drilling burrs before fitting the case.
  • Fit the lower part of the case into the housing and press until the complete snap fitting (Fig.1).

Battery replacement instructions

  • Remove the indicator from its seat, applying pressure to the retention wing bringing it to the stop with the aid of a slotted screwdriver (Fig.2).
  • Unscrew the AISI 304 stainless steel self-tapping screw with six-lobe socket for TORX®* T06 tool and remove the closing plate (Fig.3).
  • Replace the battery paying attention not to invert the polarity (see the position indicated on the cover).
  • The replacement of the battery if carried out within 10 seconds (duration of the buffer power supply) avoids the loss of the configuration parameters.
