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. With the wide-range power sup­ply unit for 100 – 240 V AC, as well as for 24 V DC, the HE 5422 dif­fer­en­tial pres­sure reg­u­la­tor can be used world­wide.
