Function principle
The sensor is used for pressure measurement.
The measured pressure is output as an electrical
signal.
General information
The sensor must not be exposed to strong
◼
impacts.
Do not exceed the static or dynamic overload
◼
limits specified in the data sheet.
Do not remove the protective cap until
◼
mounting the sensor.
Retain the protective cap for any later storage
◼
or transport.
Do not clean the membrane using abrasive
◼
agents.
Do not touch the membrane with solid bodies
◼
(neither use finger).
Safety instructions
This sensor has been assembled, tested and
◼
packed under technically safe conditions
according to currently applicable EU directives.
To maintain and ensure safe operation, observe
the information and warnings in this manual.
For installation observe and comply with the
◼
nationally applicable standards.
Sensor operation only by instructed and
◼
qualified
personnel.
Correct
and
deployment depends on proper transportation,
storage, installation and operation of the
product.
Wiring work and terminal assignment must
◼
comply with the electrical connection diagram.
Prior to power off ensure that no other parts of
◼
the installation will be implicated.
Make sure supply voltage and the ambient
◼
condi-tions
comply
with
the
specifications.
Prior to power off, check potential effects on
◼
other system components or installations.
WARNING
Destruction of the device by excessive
pressure!
Exceeding the burst pressure, even shortly, may
destroy the device..
a) Avoid any excessive pressure by taking the
appro-priate actions (see data sheet).
▪
Ensure that both pressure and nature of the
fluid to be measured are compatible with the
sensor. The fluid must be compatible with
stainless steel 1.4404 (AISI 316L) resp. 1.4301
(AISI 304), ceramic 96% AL2O3 as well as with
the nature of the seal.
▪
Only use the sensor in fluids it is intended for.
Prior

We
recommend
Installation compliant to UL certification
against
strong
The appliance is only certified for indoor use. UL
does not evaluate IP protection classes.
Device power supply must be provided by external
circuits in accordance with Class III as well as low
voltage in accordance with clause 9.4 of UL/CSA
61010-1 3rd ed. or Class 2 of UL1310.
Mandatory to use UL-approved CYJV/7 or PVVA/7
cables with voltage, current and temperature
ratings suitable for the application, but minimum
130 °C. If the device is used otherwise than
specified by the manufacturer, the device-specific
protection ratings may be impaired.
Maintenance
The sensor is maintenance-free. No special
preventive maintenance is required. Regular
cleaning and inspection of connection and seal
are recommended.
