 Electronic 
Pressure Transmitter 
HDA 4700Description:

The pressure transmitter series 
HDA 4700 has a very accurate and 
robust sensor cell with a thin-film 
strain gauge on a stainless steel 
membrane. 
The output signals 4 ..20 mA or 
0 .. 10 V enable connection of all 
HYDAC ELECTRONIC measurement 
and control devices as well as 
standard evaluation systems 
(e.g. PLC controls).
The main areas of application are 
in the or industrial sectors 
of hydraulics and pneumatics, 
particularly in applications with 
restricted installation space.
Special features:
?    Accuracy ≤ ± 0.25 % FS typ.
? Highly robust sensor cell
? Very small temperature error
? Excellent EMC characteristics
? Very compact design
? Persuasive price / 
 performance ratio
