external diameters between 20
and 160 mm. For fixing the contact
bulb to the pipe, pipe clamps are
sufficient. The contact bulb should
have direct metallic contact with
the measuring point and have firm
contact with the surface of the pipe.
Where temperatures under 200 °C are expected, a thermal compound
can be used to optimise the heat transfer between contact bulb and
pipe. Insulation must be applied at the mounting point to avoid error due
to heat loss. This insulation must have sufficient temperature resistance
and is not included in the scope of delivery.

6.2 Mounting on tanks

with an external radius up to
80 mm. If the mounting point of
the contact bulb on the tank has
an external radius greater than
80 mm, we recommend the use of
an intermediate piece designed
for the respective tank diameter,
made of a material with good thermal conductivity. The contact bulb can
be fastened to the tank by means of an angle bracket with clamping
screws, or any similar method. The contact bulb should have direct
metallic contact with the measuring point and have firm contact with the
surface of the tank.
A thermal compound can be used to optimise the heat transfer between
contact bulb and tank, if temperatures under 200 °C are expected.
Insulation must be applied at the mounting point to avoid error due to
heat loss. This insulation must have sufficient temperature resistance
