2.2 Device description
The OPTIBAR PC 5060 C is suited to applications in virtually all areas of industry. It is used to
measure the following types of pressure:
• Gauge pressure
• Absolute pressure
• Vacuum
The setup of the device is carried out via the display and adjustment unit. For further information
refer to
Keypad functions
A capacitive ceramic sensor element is used in the measuring cell.
The measuring device is supplied ready for operation. The factory settings for the process data
correspond to your order specifications.

INSTALLATION 3
Technical data
on page 59.
CAUTION!
The first digit stands for the protection of the inner electronic components against the ingress of
foreign bodies including dust. The first digit "6" means that the housing is dust-proof. The
second digit designates the protection of the inner electronic components against the ingress of
water. The second digit "6" means that the housing is waterproof and also resistant against a
strong jet of water resists. The number "7" means that the case is waterproof even under water
for a given pressure and time. The number "8" means that the housing is permanently
waterproof even under water.
3.3 Packaging
CAUTION!

3.7 Mounting
CAUTION!
•
Prior to installing the pressure transmitter, it is essential to verify whether the version of the
device on hand completely fulfils the technical and safety requirements of the measuring
point. This applies in particular to the measuring range, overpressure resistance,
temperature, explosion protection and operating voltage.
•
Check the materials used for the wetted parts (e.g. gasket, process connection, separating
diaphragm etc.) for suitability as regards process compatibility.
3.7.1 Rotating the housing
The transmitter housing can be rotated 350° for better readability of the display or access to the
wiring. A stop prevents the housing from being rotated too far.
• On all 2 chamber housings, the locking screw must first be loosened at the neck of the
housing.
i The housing can then be rotated to the desired position.
• Once the desired position is reached, the locking screw is tightened again.
INSTALLATION 3
3.7.2 Mounting the display and adjustment module
The optional display and adjustment module can be set in any one of four different positions at
90° intervals. The installation of the adjustment module is carried out as per the illustrations
below. To do so, unscrew the housing cover and insert the adjustment module clockwise. The
display can be installed rotated at 90°. It is not necessary to interrupt the power supply.

3.8 Instructions for oxygen applications
Oxygen and other gases can be explosive when brought into contact with oils, grease and
plastics, so the following measures must also be taken:
• All components of the plant, such as e.g. measuring devices must be cleaned according to the
requirements of BAM (DIN 19247).
• Depending on the seal material, certain temperatures and pressures must not be exceeded
in oxygen applications, refer to
CAUTION!
Devices for oxygen applications are sealed in PE foil and provided with a label "Oxygen! Use no
Oil". Remove this foil just before mounting the device! After removing the protection for the
process connection the label OOOO
grease and dirt should be avoided. Danger of explosion!
Technical data
will be visible on the process connection. Penetration of oil,

3.9 Venting
CAUTION!
The filter element causes a delayed pressure equalisation when the housing cover is opened or
closed quickly. During the process the measurement can change by up to 15 mbar for up to 5
seconds.
CAUTION!
In order to ensure effective ventilation, the filter element must be always free of deposits.
CAUTION!
Do not use a high-pressure cleaner to clean the housing. The filter element may become
damaged and as a result moisture can penetrate into the housing. The exception to this is the
IP69K single chamber housing.
The ventilation for the electronics housing is assured via a filter element in the vicinity of the
cable glands, which is permeable to air but water-absorbent.

4 Filter element
The filter element is integrated into the sensor assembly via a rotating metal ring. Align the
metal ring towards the bottom to better protect the filter element from deposits. Devices with
absolute pressure feature a dummy plug instead of a filter element.

Devices with second process barrier

1 Filter element
For devices with a second process barrier, the sensor assembly is completely encased by an
additional, gas-proof feedthrough. Additional venting is not required for absolute pressure
sensors. With relative pressure sensors, the ambient pressure is measured and compensated by
an additional sensor in the electronics.

3.11 Measurement setup for steam measurement
The following points should be observed in this application:
• The pressure transmitter should be connected via a siphon to protect the measuring cell
from non-permitted high temperatures.
• Siphon to be kept free of insulation.
• When using superheated steam, the siphon must be filled with water prior to start-up.
