Ten­sor Ex

Ful­ly elec­tro­nic rota­ry dri­ve for explo­si­ve are­as

Advan­ced dri­ve tech­no­lo­gy in a robust housing. 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 val­ves, e.g. flaps, val­ves, ball val­ves, dosing pumps etc., and offer a high safe­ty level. The lar­ge num­ber of moun­ting holes accord­ing to ISO 5211 and a chan­ge-over shaft sys­tem ensu­re a simp­le con­struc­tion on all stan­dard fit­tings wit­hout cost­ly bra­ckets. The dri­ves of Zone 1 are cha­rac­te­ri­zed by a high level of intrin­sic safe­ty and ope­ra­tio­nal safe­ty.
