Hamburg — Senseca has acqui­red ACS Control-System, a German company specia­li­zing in indus­trial auto­ma­tion and measu­re­ment tech­no­logy. The tran­sac­tion includes the trans­fer of all shares of ACS Control-System to Senseca. ACS will conti­nue to operate under its exis­ting brand name during a tran­si­tion period. 

Foun­ded in 1990 and head­quar­te­red in Eggen­fel­den, ACS Control-System has made a name for itself in the deve­lo­p­ment of high-quality, IoT-enab­­led products for measu­ring level, pres­sure, tempe­ra­ture and flow. These solu­ti­ons are widely used in the water manage­ment, power gene­ra­tion, phar­maceu­ti­cal and mecha­ni­cal engi­nee­ring sectors. 

The acqui­si­tion is part of Senseca’s compre­hen­sive stra­tegy to expand its indus­trial offe­ring and meet the growing demand for intel­li­gent, sustainable auto­ma­tion solu­ti­ons. “ACS adds important tech­no­lo­gies to our port­fo­lio and streng­thens our ability to offer complete measu­re­ment systems,” said Chris­tian Unter­ber­ger, CEO of Senseca. “This supports our goal of helping custo­mers auto­mate proces­ses and make better decis­i­ons based on relia­ble data.” 

ACS will be gradu­ally inte­gra­ted into Sense­ca’s opera­ti­ons, with a focus on lever­aging syner­gies between the two compa­nies’ rese­arch and deve­lo­p­ment depart­ments and expan­ding ACS’s reach through Sense­ca’s global distri­bu­tion network. “We share a commit­ment to robust, dura­ble products and have both inves­ted heavily in inno­va­tion,” said Joachim Stümpfl, CEO of ACS. “Joining forces with Senseca gives us the oppor­tu­nity to scale our tech­no­lo­gies inter­na­tio­nally and contri­bute to a broa­der indus­try portfolio.” 

The inte­gra­tion also brings imme­diate bene­fits for Sense­ca’s product deve­lo­p­ment stra­tegy. “ACS will signi­fi­cantly acce­le­rate the market intro­duc­tion of seve­ral key tech­no­lo­gies,” says Walter Vogels­ber­ger, Vice Presi­dent Busi­ness Unit Indus­try. “By inte­gra­ting radar and ultra­so­nic level measu­re­ment, we can now offer a broa­der range of measu­re­ment prin­ci­ples, ensu­ring that our custo­mers get the right solu­ti­ons for their speci­fic challenges.” 

The current owners, Joachim and Mari­anne Stümpfl, will conti­nue to hold important posi­ti­ons at Senseca. Their contin­ued invol­vement will support a smooth tran­si­tion and ensure the conti­nuity of ACS’ busi­ness acti­vi­ties, which Joachim Stümpfl will lead as Mana­ging Director. 

“This is a stra­te­gic step for both compa­nies,” added Unter­ber­ger. “With ACS, we are not only gaining new tech­no­lo­gies, but also a team that shares our values and our vision for the future of indus­trial measu­re­ment technology.”
