Technical description
These operating instructions do not take into account all
possible applications or product variations.
If you are looking for notes on your specific application, plea-
se contact the main factory.
If you need more detailed technical information on a specific
device, please ask for the corresponding Data Sheet.
NOTE!
JUMO GmbH & Co. KG, Fulda, Germany, is a
company which is certified according to
ISO 9001.
The pressure transmitters described below
conform to the requirements of DIN and VDE.
You have purchased a product which meets
even the highest requirements and fulfils, or
exceeds, all the specifications listed.
Please read these operating instructions be-
fore starting up the device.
We reserve the right to make technical altera-
tions.
Installation notes on the pressure transmitters
are included in these operating instructions. If
any difficulties should still arise during com-
missioning or while in operation, please con-
tact your nearest JUMO office or the main
factory.
All the pressure transmitters described in the-
se operating instructions are maintenance-
free.
They do not contain any components which
you could repair or exchange. Repairs can
only be carried out at the factory!
If any difficulties should still arise during com-
missioning or while in operation, please cont-
act us.

Installation
WARNING!
The device does not meet the requirements for
a „Components with a safety function" accor-
ding to the Pressure Equipment Directive
2014/68/EU.
For hazardous substances, such as oxygen,
acetylene, combustible and toxic materials, as
well as in refrigeration equipment, pressure
containers etc., the relevant regulations must
be followed! Ignoring these regulations can re-
sult in injury or damage to persons or property.
Only properly qualified personnel may work on
this equipment.
General
The operating position of the pressure transmitter is generally
unrestricted. However, in unfavourable circumstances it may
falsify the measured value.
Where there are unusual measurement conditions or media
(e.g. high medium temperatures or especially corrosive me-
dia), suitable pressure separators from our product range can
be used. Our staff will be pleased to give professional advice.
NOTE!
Unless otherwise specified, the pressure
transmitters have been calibrated vertically
with the pressure connection below, at an am-
bient temperature of 20 °C.
For installation in hydraulic plant it is appropriate
to mount the pressure transmitter with the
pressure connection above, to avoid air pockets.
When using a shut-off device, it should have
a progressive opening to ensure a slow in-
crease in pressure. Shut-off devices should
be opened slowly to avoid pressure surges.
Fitting in position
The sealing faces of the pressure transmitter and the meas-
urement point must be protected against dirt and damage.
The type and form of the thread which is used at the
measurement point is described on the back of the
instructions. In case of doubt, please contact the main factory.
The tightening torque depends on the form and material of the
seal which is used, and on the pressure connection.
The tightening torque should be at least 15 Nm but not more
than 200 Nm.
For pressure connections to EN 837 Form B, suitable seals
are JUMO hydraulic seals to DIN 16258 (flat), as in Data
Sheet 409700.
For pressure connections to DIN 3852 Form E, JUMO
provides the appropriate elastomer seals ex-works, ready-
mounted in the pressure connection.
Pipe connections to DIN 11851, DIN 28403 (KF) and
DIN 32676 (clamp) include special sealing systems, which
can be provided as accessories on request.
For the special pressure connections (process connections)
574, 580 and 581 mating connections for welding are availa-
ble as accessories in our product range.
The weld-in mating connection for process connection 653 is
supplied with the package.
Taper pressure connections to American standards, such as
NPT threads, are made hand-tight with a spanner. A sealing
compound is used to prevent the material seizing up.
Operating conditions
The pressure transmitter must be earthed, and protected
against electrostatic discharges!
The ambient and pressure-medium temperatures must not go
beyond the limits that are given in the corresponding Data
Sheet.
As for any other sensitive measuring instrument, the pressure
transmitter must not be exposed to excessively large varia-
tions in temperature. These will eventually cause changes of
the zero point and the measurement span.
Do not exceed the measurement range or the permitted over-
pressure.
For highly viscous or crystallizing media which could block the
pressure connection, the most suitable versions are those
with a frontal diaphragm.
The frontal diaphragm must not be deformed under any
circumstances – even finger pressure can be enough to cause
unacceptable deformation of the diaphragm.
Do not insert any objects into the bore of the pressure connection.
Do not direct a pressure jet onto the diaphragm.
Under extreme conditions, with rapid changes of pressure and
high pressure peaks, snubbers and pressure decoupling ele-
ments must be applied, to avoid pressure spikes (water ham-
mer) which would lead to failure of the pressure transmitter.
Electrical connection
WARNING!
Pressure transmitter must only be connected
by properly qualified personnel!
Assembly of the terminal box
• Terminal box to DIN 43650, Form A with Pg9 cable gland
2
• Conductor cross-section up to 1.5 mm
max.
• External dia. of conductor Ø 4.5 to 7 mm, protection type IP65
• Terminal box to DIN 43650, Form C with Pg7 cable gland
2
• Conductor cross-section up to 0.75 mm
max.
• External dia. of conductor Ø 3.5 to 6 mm, protection type IP65
NOTE!
The protection types specified will only be
achieved when the connector is firmly in
position with the corresponding seal.
To open up the connector
1. Unscrew the screw (1).
2. Using a small, flat screwdriver, lever the inner part (3) out
of the outer part (2) (see marking on the inner part).
The inner part can be re-assembled and inserted into the ou-
ter part in 4 positions 90° apart.
Installing the attached connecting cable
(electrical connection 12)
NOTE!
Minimum bending radius 120 mm (fixed cable
run)
The cable must not be compressed. The end of
the cable must be located in a dry room to avoid
condensation. It is best to route the cable
directly into a switch cabinet.
When lengthening the cable, ensure that
pressure
equilibration
is
provided
while
avoiding the ingress of moisture.
