Additional Information
The pressure orifice and the connectors are all made from stainless steel X2CrNiMo17-12-2/1.4404 / AISI316L. The Schrader is made from Stainless X8CrNi18-9/1.4305/303 All variants can use the following pressure cell options, based on application requirements: -1…9 Bar / 0…2.5 - 100 bar (Stainless Steel Cell X6Cr17-1.4016) The only difference between the models 520, 522 & 540 is the input and output signal, and the approvals (not relevant to WRAS) All the different type variants can be given a unique customer article number, to trace the full specification: Example: 520.99XXX 520 = Model Type 99 = Client / project specific number XXX = Unique file for client containing all the above options specified within model.
