Installation
Temperature sensor (vapor pressure princi-
ple) for Type 2430-3
− See Fig. 5-3 and Table 5-1
Risk of fire or explosion as a result of hy -
drocarbons escaping due to leakage in the
Type 2430-3 Control Thermostat or
Type 2403 Safety Temperature Monitor.
A small quantity of a flammable mixture of
hydrocarbons is used as the operating me-
dium in the Type 2430-3 Control Thermostat
(vapor pressure principle) and the
Type 2403 Safety Temperature Monitor
(STM).
Î
Mount the control thermostat and safety
temperature monitor in such a way that
in the event any operating medium es-
capes as a result of leakage, it cannot
come into contact with hot surfaces,
sparks, open flames or other ignition
sources.
The mounting position of the temperature
sensor (19) depends on the installation situa-
tion. The sensor must be immersed in the
process medium up to the marking on it. It
must be installed in a location where over-
heating or considerable idling times cannot
occur. Additionally, observe the mounting
position of the sensor (see Fig. 5-3).
Weld a welding socket with G ½ or G ¾
female thread (to match the screw gland) at
the place of installation or screw in a sensor
pocket (when installed in a heat exchanger).
Î
Seal the screw gland of the sensor.
WARNING !
Î
Contact SAMSON if the mounting posi-
tion is not as specified above.
Temperature sensor (adsorption principle)
for Type 2430
Î
See Fig. 5-2 and Table 5-1
Galvanic corrosion due to incorrectly
selected materials of the mounting parts.
On installing the sensor or thermowell, only
combine the same kind of materials (e.g.
stainless steel with stainless steel or copper
together with other copper materials).
The temperature sensor (19), even together
with a thermowell (20), can be installed in
any position as required. However, make
sure its entire length is immersed in the pro-
cess medium to be controlled. It must be in-
stalled in a location where overheating or
considerable idling times cannot occur.
If the sensor is to be used with a thermowell,
only use original SAMSON thermowells.
Weld a welding socket with G ½ or G ¾ fe-
male thread (to match the screw gland) at
the place of installation.
Î
Seal the screw gland of the sensor.
