High-resolution measuring technology - flexbly pro-grammed, robust and precise
Mechanical position indicators are al-ready used successfully on shafts and spindles for displaying position values. Electronic digital position indicators are, formally speaking, a logical further development of their mechanical coun-terparts. Thanks to comparable outer dimensions and the track-proven slip-on principle on the shaft, reconfiguration from mechanical to electronic-program-mable indicator technology is a matter of minutes.
The standalone indicators of the DE range are particularly effective as an alternative to mechanical counters if no suitable gearing is available for these. Their free programmability also permits positive and negative display values or operation in angled mode.
The ProTool DE software solution is mainly of interest for mechanical engineering applications, because it can be used to program DEs directly before they are mounted on adjustment spindles.

Therefore only one basic device type has to be kept on stock, which is set up in ac-cordance with the respective application requirements.
Automated manual work
As an extension to the electronic standalone units of the DE range, the AP models also feature a bus interface. During bus-controlled operation,can be communicated setpoint and actual values between the individual absolute position indicators and a higher-level controller.
Teamwork in bus operation
This semi-automated spindle adjustment offers a much higher level of process reli-ability and shortens set-up times during format changes considerably. Due to the display of the set value directly on the shaft and feedback of the manually
|
correctly set actual value, incorrectly set stops and tool positions are a thing of the past. The overall system is only enabled when all spindle positions have been correctly signaled, so that of-spec material or damaged tools caused by incorrectly set adjusting shafts are no longer possible.
Benefits
The electronic SIKO position indicators feature a series of software assisted func-tions:
■ The spindle pitch, direction of rotation and decimal point can be freely programmed
^ Length or angle indication: Two modes are possible
^ Incremental measurement function, ofset input: Flexible adaptation to user specifications is possible
^ Zero setting of the shaft is performed at the touch of a button

The ultimate achievement: Maximum dimen-sioned hollow shaft opening
in relation to its
size.

Truly SIKO - the AP04 has a functional indus-
trial design in a highly-integrated electro-
mechanical construction. Its 2-line LCD display
provides maximum read-ing accuracy directly on
the shaft.
