6. Mechanical Connection
The places where pressures are taken should be prepared according the
following specifications for the screw-in threads. This is very important for
pressure sensors with front diaphragm, because otherwise the diaphragm could
be damaged. For sealing, please use sealing discs acc. DIN 16258 or profile
washers. The maximum initial tension depends on the material, the shape of the
used sealing and the mechanical connection of the pressure sensor.
The given tensions should not be exceeded.
50 Nm for pressure sensors with metallic sealing cone (hereby, there could be
for small measure ranges a deviation of the zeropoint of maximum 1%. This
deviation could be adjusted, with the zero point potentiometer see chapter
"Maintenance").
80 Nm for pressure sensors with pressure connection acc. DIN 16288,
and/or flash front diaphragm with O-ring.
There should be no vibrations and/or no radiation of heat near the mounting
position of the sensors. Please pay attention that the giving operating limits are
not exceeded. After the mechanical and electrical connection the sensor is ready
for operation.
