Mounting on tanks
The geometry of the contact bulb has been
designed for vessels with an external radius
up to 160 mm. If the mounting point of the
skin mounting contact bulb on the tank has
an external radius greater than 160 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 heat conductive paste can be used to optimise the heat transmission between contact
bulb and vessel, 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 and is not included in the scope of delivery.
When mounting a rotatable and inclinable DiwiTherm
®
thermometer, the specific
instructions must be followed. In order to set the indicator to the desired position, the
following steps must be taken:
1. The lock nut or union nut must be loosened at the process connection.
