Linea­ris TE Ex 1

Ful­ly elec­tro­nic dam­per actua­tor for Ex-Zone 1

With the Ten­sor series, ARIS offers an inno­va­ti­ve genera­ti­on of elec­tro­ni­cal­ly con­trol­led actua­tors. The Ten­sor is based on a low-play pre­cisi­on gear­box in com­bi­na­ti­on with a brush­less DC motor. In the Ten­sor, the com­ple­te mecha­ni­cal shut-off sys­tem was repla­ced by a wear-free and non-con­tact posi­ti­on detec­tion based on the Hall effect. This sen­sor tech­no­lo­gy was deve­lo­ped years ago for use in the auto­mo­ti­ve indus­try and has pro­ved its­elf through extre­me robust­ness, wide tem­pe­ra­tu­re ran­ge and high relia­bi­li­ty. ARIS actua­tors of the series Ten­sor Ex are desi­gned for indus­tri­al use in zone 1 hazar­dous are­as. They are used for the actua­ti­on of regu­la­ting and shut-off devices, e.g. flaps, val­ves, ball val­ves, dosing pumps etc., and offer a high safe­ty level. The dri­ves of Zone 1 are cha­rac­te­ri­zed by a high level of intrin­sic and ope­ra­tio­nal safe­ty.

A stain­less steel high-helix spind­le with dry­s­pin® spind­le nut made of high-per­for­mance poly­mer ensu­res reli­able and main­ten­an­ce-free ope­ra­ti­on. Due to the high lead, the requi­red engi­ne speed is noti­ce­ab­ly redu­ced in com­pa­ri­son to the clas­sic design, so that the engi­nes run signi­fi­cant­ly smoot­her and quie­ter, thus signi­fi­cant­ly increa­sing the ser­vice life of the engi­nes. Ins­tead of the com­mer­ci­al­ly avail­ab­le cas­tings, ano­di­zed alu­mi­num machined parts are used with the Linea­ris TE, which are signi­fi­cant­ly more robust with a low weight. The Linea­ris has been deve­lo­ped by prac­ti­tio­ners. Long holes in the bra­ckets allow easy assem­bly. The dry run­ning spind­le nut pre­vents dirt build-up so that lar­ge and expen­si­ve bel­lows designs are no lon­ger requi­red. Like­wi­se, the regu­lar gre­a­sing is avoi­ded by the lub­ri­cant-free con­struc­tion.

The design of the Linea­ris lift unit also fol­lows the Atex gui­de­li­nes, so that the com­bi­na­ti­on of line­ar unit and zone 1 dri­ve form a reli­able unit.
