2.2 Description
Model E-10: Process connection with internal diaphragm (standard version)
Model E-11: Process connection with ush diaphragm for highly viscous or crystallising media that may clog the bore
of the process connection.
By means of a sensor element and by supplying power, the prevailing pressure in your application is converted into an
amplied standardised electrical signal via the deformation of a diaphragm. This electrical signal varies in proportion to
the pressure and can be evaluated accordingly.

3.5 Special hazards
DANGER!
Danger to life due to loss of explosion protection
Non-observance of these instructions and their contents may result in the loss of explosion protection.
▶
Observe the safety instructions in this chapter and further explosion protection instructions in these
operating instructions.
▶
Observe the information given in the applicable type examination certificate and the relevant country-
specific regulations for installation and use in hazardous areas (e.g. IEC 60079-14, NEC, CEC).
WARNING!
Physical injury and damage to property caused by hair-line cracks
The service life of the pressure transmitter is limited by a maximum number of load cycles.The maximum
number depends on the pressure prole of the application (extent of change in pressure, time of pressure
rise and pressure drop, ...). Once the maximum number of load cycles has been exceeded, it can lead to
leaks through hair-line cracks, which can cause physical injury and damage to property.
▶
Request the maximum number of load cycles from the manufacturer.
▶
Replace the pressure transmitter once it has exceeded the maximum number of load cycles.
▶
Take safety measures to eliminate hazards due to hair-line cracks.
WARNING!
Physical injuries and damage to property and the environment caused by hazardous media
Upon contact with hazardous media (e.g. oxygen, acetylene, ammable or toxic substances),
harmful media (e.g. corrosive, toxic, carcinogenic, radioactive), and also with refrigeration plants and
compressors, there is a danger of physical injuries and damage to property and the environment.
Should a failure occur, aggressive media with extremely high temperature and under high pressure or
vacuum may be present at the instrument.
▶
For these media, in addition to all standard regulations, the appropriate existing codes or regulations
must also be followed.
▶
Wear the requisite protective equipment.

WARNING
Danger to life due to loss of explosion protection from damaged process connection
The diaphragm of the ush process connection is a safety-relevant component. If it is damaged, the
explosion protection is no longer guaranteed.Through any explosion resulting from this, there will be a
high danger to life.
▶
Before commissioning the pressure transmitter, the diaphragm of the ush process connection
should be checked for visible damage.
▶
Leaking uid is indicative of a damaged diaphragm.
▶
Protect the diaphragm from contact with abrasive media and against any impacts.
▶
Observe the specications for the use of the pressure measuring instrument in combination with
aggressive/corrosive media and for avoiding mechanical hazards.
▶
Only use the pressure transmitter if it is in perfect condition with respect to safety.
WARNING
Danger to life through improper mounting
Improper installation can lead to the loss of the explosion protection and to life-threatening situations.
▶
Adhere to the permissible ambient and medium temperatures which are valid for this area on
the basis of the specied temperature classes. (→ see chapter 3.8 “Special conditions of use
(X conditions)” and chapter 9 “Datos técnicos”).

5.3 Electrical mounting
WARNING!
Danger to life through improper mounting
If the pressure transmitter is not mounted properly, the explosion protection can no longer be ensured.
▶
Do not remove the cable connection.
▶
Use the electrical connection as originally supplied. It must not be bypassed or changed (except for
the cable length).
▶
Fine-stranded leads with bare ends must be finished with end splices (cable preparation)
■
Use and assemble connection cable that is suitable for the application.
■
Clamp the free cable end to a suitable certied clamp box or outside the hazardous area.
■
Use the pressure transmitter with shielded cable and ground the shield on at least one end of the lead, if the lines
are longer than 30 m or leave the building.
■
Ground the case via the process connection to protect the pressure transmitter against electromagnetic elds and
electrostatic discharge.Include the case in the equipotential bonding of the application.
For instruments with cable outlet, the shield is connected to the case.The simultaneous connection of the case and the
cable shield to ground is only permitted if any potential losses between the shield connection (e.g. at the power supply)
and the case can be excluded (see EN 60079-14).
Additional information for version E-1*-*-***-**-**DX**-** with protective cap
For installation with electrical conduit, the metal protective cap can be removed.
For installation without electrical conduit, the metal protective cap must not be removed.
Requirements for electrical connection
■
Ingress protection IP67 in accordance with IEC 60529 (protect drainage openings of the metal protective cap from
dirt to prevent water accumulation).
■
For cable outlets, make sure that no moisture enters at the cable end.
