7. Mounting instructions for contact bulb
7.2 Mounting to vessels
The geometry of the contact bulb
has been designed for vessels
with an external radius up to
80 mm. If the mounting point
of the skin mounting 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 vessel diameter, made
of a material with good thermal conductivity. The contact bulb should
be fastened to the vessel by means of an angle bracket with clamping
screws, or any similar method. The skin mounted contact bulb should
have direct metallic contact with the measuring point and have firm
contact with the surface of the vessel.
A heat conductive paste can be used to optimise the heat
transmission between skin mounted contact bulb and the vessel,
if temperatures under 200 °C are to be expected. Lagging must be
applied where the skin mounted contact bulb has been mounted, in
order to avoid error due to heat loss. This lagging must have sufficient
temperature resistance and is not provided with the instrument.
