Standard installation
•
Probes are mounted to the process connection with threaded connections or flanges
and are usually also secured with these. If during this installation there is the danger
that the probe end moves so much that it touches the tank floor or cone at times, the
probe must, if necessary, be shortened and fixed down. The easiest way to fix the rope
probes is to screw them to the internal thread on the lower end of the weight. Thread
size, see page 23.
•
The ideal installation is mounting in a screwed joint / screw-in sleeve which is internally
flush with the container ceiling.
•
If installation takes place in a nozzle, the nozzle should be 50 ... 150 mm in diameter
and should not be more than 150 mm high. Installation adapters are available for other
dimensions, see »Accessories« on page 77.
Probe length
•
The measuring range is directly dependent on the probe length. If the probe is not
fixed at the bottom end, the following distances to the container floor must be
observed:
– Rope probe: 150 mm
– Rod probe: 100 mm
– Coax probe: 30 mm
It is better to order probes too long than too short since it is possible to shorten the
probe if necessary.
