Ten­sor Ex 2/22

Ful­ly elec­tro­nic rota­ry dri­ve for Ex-Zone 2 und 22

Advan­ced dri­ve tech­no­lo­gy in a stur­dy housing with com­pact dimen­si­ons. ARIS actua­tors of the series Ten­sor Ex are desi­gned for indus­tri­al use in zones 2 and 22, which are poten­ti­al­ly explo­si­ve, accord­ing to their mar­king. 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 robust, pow­der-coated housing and the metal hood of the dri­ves ensu­re safe and reli­able ope­ra­ti­on in zones 2 and 22. The wide ran­ge of moun­ting holes accord­ing to ISO 5211 and a chan­ge-over shaft sys­tem ensu­re simp­le assem­bly on all stan­dard fit­tings wit­hout cost­ly bra­ckets. For the zones 2 and 22 no pres­su­re-pro­of encap­su­la­ti­on is necessa­ry so that the dri­ve has signi­fi­cant­ly less weight than dri­ves of the zone 1.
