1 General
If you have any queries regarding technical details or the suitability of the unit for your
application, please contact our Technical Sales Department.
The series HDA 4800 pressure transmitters are individually tested and calibrated at a
computer operated test station. They are maintenance-free and operate perfectly when used
according to the data (see Technical Specifications). However, if there is a cause for
complaint, please contact HYDAC Service. Interference by anyone other than HYDAC
personnel will invalidate all warranty claims.
2 Safety information
Before commissioning, check the instrument and any accessories supplied. Before
commissioning, please read the operating instructions. Ensure that the instrument is suitable
for your application.
If the instrument is not handled correctly, or if the operating instructions and specifications
are not adhered to, damage to property or personal injury can result.
3 Installation
The units can be mounted directly to the hydraulic system via the thread connection. In order
to prevent mechanical damage when dealing with critical applications involving heavy
vibrations or blows, for example, we recommend securing the pressure transmitter with an
elastomer clamp and decoupling the hydraulic ports via a Minimess hose. The recommended
mounting position is vertical with the pressure connection pointing upwards in hydraulic
applications, in pneumatic applications, the pressure connection must point downwards. The
tightening torque for the G 1/4 A thread connector is approx. 20 Nm. The electrical
connection must be carried out by a qualified electrician according to the relevant regulations
of the country concerned (VDE 0100 in Germany).
Caution!
Installation of the HDA 4800 must be carried out using a spanner (AF 27)
suiting the hexagonal nut of the pressure port.
Do not install the unit by gripping the housing, as this would damage the
housing or the entire unit.
The series 4800 pressure transmitters carry the
-mark. A certificate of conformity is
available on request. The EMV standards EN 61000-6-1, EN 61000-6-2, EN 61000-6-3 and
EN 61000-6-4 apply. However, the stipulations of those standards are met only if the sensor's
housing has been correctly earthed by a qualified electrician. When installed in a hydraulic
block, earthing the block via the hydraulic system is sufficient. When using hose mounting the
housing has to be grounded separately.
