Rod extension/centering device HMP40 for FMP57
For FMP57 with rope probes, the rod extension/centering device HMP40 is available as an
accessory. It must be used if the probe rope would otherwise come into contact with the
lower edge of the nozzle.
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 used in bulk
solids. We deliver this component separately from the device. Please order a
correspondingly shorter probe length.
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
with product.
Mounting in nozzles ≥ DN300
If installation in nozzles ≥ 300 mm (12 in) is unavoidable, installation must be carried out
in accordance with the following diagram in order to avoid interference signals in the near
range.
1 Lower edge of the nozzle
2 Approximately flush with the lower edge of the nozzle (±50 mm)
3 Plate, nozzle ⌀ 300 mm (12 in) = plate ⌀ 280 mm (11 in); nozzle ⌀ ≥ 400 mm (16 in) = plate ⌀ ≥
350 mm (14 in)
4 Pipe ⌀ 150 to 180 mm
