Electronic hollow shaft position indicator with serial output

The electronic indicator EP-RS includes in the same case a position indicator and the display unit, setting up a device for measuring linear or angular shiftings: compact, easy assembling and applicable in several type of industry machineries (packaging, wood, aluminium, coil etc).
The display has 6 digits besides a sign with range from -999999 to 999999 and the 10mm high digits allow a very good readability also by distances.
➤ With the 3 frontal keys is possible to programme the value on the display for every turn of the hollow shaft and start the reset/preset functions of quota, absolute/relative quota, conversion mm/inches and reading range in degrees. There are also available 3 distinct origins for the correction of quota by using different tools and the offset function for the balancing of tool wear.
The electronic part is seated inside an elegant and strong case made of self-extinguishing and shockproof material.
The drive shaft turns on precision ball bearings.

• EP-RSwith external power supply 12-25Vdc and internal rechargeable battery (functioning for 6 months without power supply), serial output RS485 protocol MODBUS RTU for communication with remote units.
• EP-RS.MAN is for manual positioning (for ex. manual shape change): the supervision unit (PLC, computer) trasmits the value to each EP-RS.MAN and the operator moves the axis by hand to reach this value.
