HE 5422 Dif­fe­ren­tial pres­sure regu­la­tor

It can be used to cover dif­fe­ren­tial pres­sure ran­ges from ± 2.5 to ± 1000 mbar, with a basic accu­racy of ± 1% of the final value. The clea­ning range of the com­pact con­trol­ler is defi­ned by a lower and an upper thres­hold. Due to the wide range power sup­ply for 100 – 240 V AC, as well as for 24 V DC, the dif­fe­ren­tial pres­sure con­trol­ler HE 5422 can be used world­wide.
