Type of probe 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
(® ä 25).
• The ideal installation is mounting in a screwed joint / screw-in sleeve which is internally flush with the
container ceiling.
• Alternative: nozzle mounting
1 Mounting with screwed joint; flush with the container ceiling
2 Nozzle mounting
• Permissible nozzle diameter: £ 150 mm (6 in).
For larger diameters the near range measuring capability may be reduced.
• Permissible nozzle height: £ 150 mm (6 in).
For a larger height the near range measuring capability may be reduced.
Extension rod for FMP57
If - for installations in nozzles > 150 mm (6 in) - the probe could touch the lower nozzle edge due to moving
materials in the container, we recommend using an extension rod with or without centering disk (HMP40, see
"Accessories").
This accessory consists of the extension rod corresponding to the nozzle height, on which a centering
disk is also mounted if the nozzles are narrow or when working in bulk solids. This component is delivered
separately from the device. Please order the probe length correspondingly shorter.
Only use centering disks with small diameters (DN40 and DN50) if there is no significant build-up in the
nozzle above the disk. The nozzle must not become clogged by the product.
Installation in nozzles ³ DN300
If installation in ≥ 300mm/12" nozzles is unavoidable, installation must be carried out in accordance with the
sketch on the right.
