Data
Pressure switches types RT 5, RT 110, RT
116, RT 200
Max. test pressure
RT 110: 8 bar
RT 5, RT 116, RT 200: 25 bar
Fitting
Damp out strong pressure pulsations.
A damping coil will often be sucient.
Insert a water-lled tube loop as a
temperature lock (e.g. a 10 mm Cu tube) if
at high plant temperatures there is a risk
that the pressure connection of the switch
will become heated to more than 150 °C.
Position the pressure control so that on
water plant it cannot be exposed to frost.

It can operate on an air cushion, for
example. To assure IP65 grade of RT
enclosure, it is necessary to assemble the
plug shown in the g. 5.
Setting
To set a pressure switch, the seal cap (1)
must be removed and the range setting
screw must be rotated, at the same time
reading the main scale (2), see g. 1.
The dierential is set by rotating the
dierential adjusting nut (3) to the value
indicated by the use of the nomogram in
g. 2. The maximum operating pressure is
thus the sum of the setting pressure and
the dierential.
Example
It is desired to control the pressure in an
oilred steam boiler by the use of an
RT 116.
Maximum pressure 9 bar.
Minimum pressure 8.2 bar.
Dierential 9 - 8.2 = 0.8 bar.
1. Connect the oil burner to terminals 1-2
of the pressure switch.
2. Set the pressure switch for 8.2 bar by
rotating the range setting screw.
3. Set the dierential adjusting nut (3) at
the digit 6 which is found by reading
the nomogram in g. 2.
