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 rm

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 sucient

temperature resistance and is not provided with the instrument.
