DD51-E of ELESA: the direct drive electronic position indicator with battery power supply

DD51-E, electronic position indicator with battery power supply, joins the current DD50, DD51, and DD52R mechanical indicators. Its sizes make it interchangeable with the intermediate measurement version DD51.

Thanks to the wide LCD display with 5 digits of 8,00 mm height, DD51-E ensures excellent readability even from a distance and from different viewing angles; the window in transparent technopolymer moulded over the case protects the display against accidental shocks and avoids liquid penetration inside the indicator.

The ultrasonic welding between the base and the case avoids dust and liquid penetration, ensuring a high protection class (IP65 or IP67); this makes DD51-E suitable for applications requiring frequent washing cycles, even with water jets. The bushing and the pressure screw for the assembly to the shaft are made of AISI 304 stainless steel, to ensure high corrosion resistance.

What makes the DD51-E position indicator “one item for all needs” are the programmable parameters.

Through the three function keys, it is possible to select the different available functions (absolute or incremental measure mode, conversion of the measure unit, - mm/inches for linear measure, degrees for angular measure -, selection of the absolute counter, selection of the offset value), and to program many parameters, including: reading after one revolution of the control shaft, the maximum rotation speed and direction, the display orientation and the type of resolution.

Completing the profile of the innovative direct drive electronic position indicator offered by ELESA, is a further characteristic: the long duration (over 5 years) of the internal lithium battery which can be easily replaced without the disassembly of the indicator from the shaft and without the loss of the configured parameters.
