4 HDA 4700 / 4400 with flush membrane

1 General

Pressure transmitter HDA 4000 with a flush membrane was designed specifically for
applications in which a standard pressure connection could become blocked, clogged or
frozen by the particular medium used.
Additional fields of application can be found in processes with changing media, in which
residues could lead to mixing or contamination of the media.
The pressure connection is achieved with a fully-sealed stainless steel front membrane
filled internally with a pressure transfer fluid. The process pressure is transmitted
E
hydrostatically to the measurement cell via the pressure transfer fluid.
If you have any queries regarding technical details or the suitability of the unit for your
application, please contact our Technical Sales department.
EDS 4000 pressure switches are individually tested and calibrated at a computer operated
test station. The pressure switches are maintenance-free and operate perfectly when used
according to the specifications (see Technical Specifications). However, if there is a cause
for complaint, please contact HYDAC Service.
Interference by anybody other than HYDAC personnel will invalidate all warranty claims.
