Temperature sensor
NOTICE
!
Galvanic corrosion due to incorrectly se-
lected 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 (25), even together
with a thermowell, can be installed in any
position as required. However, make sure its
entire length is immersed in the process me-
dium to be controlled. It must be installed in
a location where overheating or consider-
able idling times cannot occur.
Note
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.
Installation with thermowell
When a thermowell is used, a welding sock-
et with G 1 female thread must be used.
1. Seal the thermowell into the welding
socket.
2. Insert the sensor and tighten it with the
clamping screw.
