Operating instructions

Pressure transmitter


Before you take the pressure switch into operation,
make sure to read these operating instructions thoroug-
hly. In the event of damages due to the nonobservance of
these instructions, improper operation or use of the
switch for purposes for which it is not intended, the
warranty becomes null and void. We shall not be held lia-
ble for resultant consequential damages.
The switch is to be installed and removed by technicians
The applicable certified national safety regulations for the
operation of pressure measuring devices shall be observed.
In the installed condition the respective devicespecific
requirements on the type of protection must be fulfilled.

Note: Only versions that have the number 1 in the fifth
place after the point in the product number
(692.XXXX1XXXX) can be calibrated.


Factory setting
Pressure 0, output signal 0 or 4 mA or 15 - 25 mV (typically
20 mV) with voltage output.
Maximum pressure = maximum output signal.

Calibration options

Zero point with potentiometer, varnished white
(fig. 2)
With pressure 0, the output signal can be adjusted by
+ 10 % fs. However, with 0 - 10 V versions at a pressure of
10 % fs, the +/- 10 % adjustment has a low limit of 20 mV.

Slope with potentiometer, varnished red (fig. 2),
+/- 10 % of the full scale output, can be adjusted with ap-
plication of appropriate pressure.

Calibration procedure
– Make electrical connection according to diagrams in

fig. 1.

– Unscrew four connector fastening screws, pull off

connector to render potentiometers accessible.

– With pressure regulator of class 0.6 or better apply lo-

wer pressure.

– Adjust zero point output signal with zero point po-

tentiometer (varnished white, fig. 2).

– Apply desired upper pressure and adjust output signal

with slope potentiometer (varnished red, fig. 2).

– Repeat this process two or three times until the values

are within the tolerance range.

– After the calibration apply varnish to all potentiometers


Seal tight connection part.
