Produkt anfragen
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.
