Electronic
Pressure Switch
EDS 3400
with Flush Membrane
Description:
The electronic pressure switch
EDS 3400 with a ush membrane was
designed specically for applications in
which a standard pressure connection
could become blocked, clogged or
frozen by the particular medium used.
Further applications include processes
where the medium changes frequently
and any residues could cause mixing or
contamination of the media.
Like the standard model, the EDS 3400
with ush membrane has a stainless
steel measurement cell with a thin
lm strain gauge for relative pressure
measurement in the high pressure
range.
The pressure connection is achieved
with a fully-sealed stainless steel
front membrane lled internally with
a pressure transfer uid. The process
pressure is transmitted hydrostatically
to the measurement cell via the
pressure transfer uid.
Depending on the type, the instrument
can have up to 2 switching outputs and
a switchable analogue output
(4 .. 20 mA or 0 .. 10 V).
Special features:
- Pressure connection has a ush
membrane
- 1 or 2 PNP transistor switching
outputs, up to 1.2 A load per output
- Accuracy ≤ 1 % FS
- Optional analogue output selectable
(4 .. 20 mA / 0 .. 10 V)
- 4-digit digital display
- Rotation in two planes (axes)
for optimum alignment
- Measured value can be displayed in
bar, psi or MPa
- Simple operation with key
programming
- Switching points and switch-back
hystereses can be adjusted
independently
- Many useful additional functions
- Option of Desina®-compliant
pin conguration with diagnostic
function

EDS 3400 for self diagnostics:
The DESINA®-compliant pressure
switch has been specially developed
for customers in the machine tool and
mechanical engineering sectors and
complies with the DESINA® specication.
A diagnostic signal enables errors to be
detected and an "ERROR" message also
appears in the display. The electrical
connection is a round 5-pole M12x1
to IP 67 in accordance with DESINA®
requirements.
