6.4.1 Additional Attachments
6.4.1.1 Contact elements
Limit signal transmitters (contacts) and capacitive rotation angle transducers
with an output signal proportional to the angular position can be fitted into a
housing augmented by a corresponding bayonet ring connector.
A certain minimum pressure level is required to operate this kind of contact ele-
ment, which is why there is a lower limit for the mbar measuring ranges. This
limit depends on the model type and is stated in the section ‚General‘.
The measuring deviation increases by ±0.5% per contact when the contacts are
driven and switched.
For more information and the order key, please refer to the data sheet:
• for limit switch in data sheet KE
• for rotation angle converter in the data sheet KE09
6.4.1.2 Fluid charging
Under aggravated operating conditions, such as vibrations and extreme pres-
sure fluctuations, or in order to avoid condensation forming if used outdoors, the
casing can be filled with the following fluids depending in the type of contacts in-
stalled:
without contacts
Silicon oil
Low-action contacts
Silicon oil
Magnetic spring contacts
Silicon oil
Inductive contacts
no filling possible
Rotation angle transducer
no filling possible
6.4.1.3 Marker needle
A settable red marker can be attached to the scale to clearly show a certain
pressure (limit value).
6.4.1.4 Trailing needle
The railing needle is 'dragged' with the measured value indicator. As there is no
fixed connection between the two needles, one-off maximum values are stored.
The trailing needle can be reset using an adjusting dial in the window. Trailing
needles cannot be used in conjunction with contacts. A certain minimum pres-
sure level is required to move the drag indicator, which is why there is a lower
limit for the mbar measuring ranges. This limit depends on the model type and
is stated in the section ‚General‘.
