WARNING
- In order to avoid hazards to operators and
damages to the device, the following instructions have to be
performed by qualified technical personnel.
WARNING
- Adhere to the safety and operating instructions
stated in the operation manual. Effective regulations on occupa-
tional safety, accident prevention as well as national installation
standards and approved engineering techniques must in addi-
tion be complied with.
Limitation of liability and warranty
Failure to observe mounting instructions / operating manual
or technical regulations, improper use and use not as in-
tended, and alteration of or damage to the device will result in
the forfeiture of warranty and liability claims.
Intended use
Ensure that the medium is compatible with the media-wetted
parts and that the device is suitable for the application without
restrictions. The technical data listed in the current data sheet is
binding.

Mounting
Danger of death from airborne parts, leaking fluid, electric shock
-
Always mount the device in a depressurized and de-energized condition!
-
Operate the device only within the specification! (according to data sheet)
Danger of death from improper installation
DANGER
-
Installation must be performed only by appropriately qualified persons who have read and understood the
operating manual.
Probe
Fasten the probe properly
according to your requirements.
Different mounting accessory is available from BD|SENSORS (mounting clamps, terminal clamps and mounting flanges).
NOTES for flange and screw-in versions:
- Use a suitable seal for the medium and the pressure to be measured, if necessary. For connections according to
DIN 3852 do not use any additional sealing material such as yarn, hemp or Teflon tape!
- The permissible tightening torque depends on the conditions on site (material and geometry of the mounting point).
The specified tightening torques are valid for the probe and must not be exceeded!
- When installing the device, avoid high mechanical stresses on the pressure port! This will result in a shift of the
characteristic curve or to damage, in particular in case of very small pressure ranges.
Removal of protective cap (if necessary)
For the protection of the diaphragm, some of the probes have a
plugged-on protection cap. If the device shall be used in high-
viscosity media such as sludge, a removal of the cap before
start-up is necessary. Thus, the sensor becomes flush, and the
medium will attain quickly to the diaphragm.
NOTE -
Make sure that the sensor (7) under the protection cap
will not be damaged!
Removal by hand
1.
Hold the probe in a way that the protection cap points up-
wards.
2.
Hold the probe with one hand on the sensor section (1).
3.
Remove the protection cap (2) with the other hand.
Removal with a tool (recommended)
Fig.2 Removal of protection cap
1.
Hold the probe in a way that the protection cap points up-
wards.
2.
Slide a small tool such as a screwdriver (8) straight through
two opposite drill holes in the protective cap (2).
3.
Lever it off by moving up the handle of the screwdriver.
