F20-F18-F18R

Dimensions display and magnetic band

These are dimensions display with integrated position sensor to be combined to the magnetic band in order to carry out a complete device for measuring linear or angular shiftings.
It is possible to select the count direction, the position of the decimal point on the displayed dimension, and the measure unit (mm or inches, degrees).
The displayed dimension may be corrected through a programmable factor with values ranging from 0,00001 and 999999. The dimension display may be carried out either in absolute or in incremental mode by simply pressing the suitable key; this relative measures within the measuring field may be carried out. It is also possible to set a preset dimension that may be recalled through the suitable key. There are also available distinct origins for the correction of quota by using different tools and the offset function for the balancing of tool wear. The keys enabling to recall the preset dimension and the absolute dimension/relative dimension switch may be inhibited in a very simple way.
On the display all activated functions are showed by a symbol. The run-down of battery is indicated with occasional blinking, 1 month before the complete flat the indication remains on; changing of battery is carried out in very easy way and without loosing quota, by standing machine.
Versions:
• F20 with internal power supply (4 batteries type AA of 1,5V: two-year-life);
• F18 with internal power supply (2 batteries type AA of 1,5V: one-year-life);
F18R with external power supply 10-25Vdc and internal rechargeable battery (functioning for 5 months without power supply), serial output RS485 protocol MODBUS RTU for communication with remote units.

SB - MODULAR SUPPORT FOR MAGNETIC BAND  

Modular support in anodized aluminium for P25/10 and P50/10, magnetic band, supplied in standard modules L=500mm; custom lenghts available on request.

1 module of 500mm
3 modules of 500mm

 


 

The transducers MT, MTV, MTP, the magnetic strip P50/10, the magnetic rings AM14 or AM20 are incremental systems without contact for linear or angular measures.
● Transducers MT (horizontal mounting) and MTV (vertical mounting) in shock-proof, self-extinguishing technopolymer; MTP (horizontal mounting) in aluminium case.
● Magnetic Band P50/10: the band consists of a magnetized plastic ferrite strip with alternate magnetic poles of 5 mm pitch, carried by a stainless steel strip-band. Mechanical protection of the plastic ferrite strip is supplied by a stainless steel band.
● Magnetic rings: AM14 with bore ø14, AM20 with bore ø20. Supported by an aluminium ring.
