Electronic hollow shaft position indicator, battery supplied

The EP7 electronic indicator, which is supplied with an internal battery and includes in the same case the position sensor and the display unit, measures linear or angular movements,  applicable to many types of industrial machinery (packaging, woodworking, aluminium, coil etc).

Main features:
Simple assembly through the hollow shaft
Powered by long battery life, easy replacement from the front (without loss of quote and parameters)
The display has 7,5mm-high-digits, which allow excellent readability also from a distance.
The hollow shaft is made of stainless steel; shockproof, self-extinguishing plastic container.

Main functions:
▪ Directly programmable by the three front keys
On the display all activated functions are shown by a symbol.
Setting of the value shown on the display for every turn of the hollow shaft;  measurement direction, number of decimals.
Parameters of reset/preset; absolute/relative reference; mm/inches conversion and display in degrees. 3 distinct origins for the correction of by using different tools and the offset function for the compensation of tool wear.

Movement knob PM EP7 for indicator EP7

The motion-knob is directly assembled on the shaft of programmable position indicator EP7.
On request stickers (neutral or with Fiama logo), which on the motion-knob’ s front shows the increase or decrease of measure wise.
Material: anodized aluminium.

Overall dimensions

Shaft block FL-EP7
With the drive shaft block flange on the indicator as a compact unity, we obtain a safe blocking of the drive shaft. Flange in technopolymer, block component in aluminium.

Spacer FL-EP7
The spacer flange in shock-proof technopolymer can easily adapt the indicator to different dimensions requirements.
