DD51-E of Elesa+Ganter: the direct drive electronic position indicator with battery power supply
The device gives the possibility of reading the absolute or incremental positioning of a machine component.
The family of Elesa+Ganter position indicators is enhanced by a new introduction that completes and perfects an already wide range, for many decades capable of presenting the market with extremely diverse analogue, digital, and analoguedigital solutions.
With the range of direct drive position indicators, Elesa+Ganter is in fact able to offer components that can be fitted directly on the control shaft and that are connected to the machine through a back position referring pin, setting itself apart - as sort of operation - from other gravitational and fixed reaction position indicators.
DD51-E, electronic and with battery power supply, joins its predecessors, the DD50, DD51, and DD52R. Its sizes make it interchangeable with the intermediate measurement version DD51; the 5-digit display, on the other hand, reminds of the DD52R. It is indeed thanks to the wide LCD display with 8.00 mm height digits that the 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.
The base and the case are made of high-resistance polyamide based technopolymer and are ultrasonically welded, which prevents separation and avoids dust and liquid penetration, ensuring a high protection class (IP65 or IP67); this makes the DD51-E suitable for applications requiring frequent washing, 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.
