Aggressive liquid level probe P142

analogATEXstainless steel

The  membrane of the  P142  level  transmitter is  welded  directly  to the  housing and  does  not have to be  sealed  internally  with an  O-ring.  The medium is only in contact with highly resistant  CrNi stainless steel  1.4571 and there is no weak spot along an elastomer seal.  The protective cap can be removed if necessary and the thread underneath can be used as a process connection.  ATEX certified and with FEP suspension cable, the model  is  ideal  for  potentially  critical  areas  and  media.  The  measuring  range  can be  adjusted on  site  using the HART  interface.  Our modular  design concept provides a wide variety of products.
