• Pipe diameter: > 40 mm (1.6") for rod probes
•
Rod probe installation can take place up to a diameter size of 100 mm. In the event of larger
diameters, a coax probe is recommended.
• Side disposals, holes or slits and welded joints that protrude up to approx. 5 mm (0.2") inwards
do not influence the measurement.
• The pipe may not exhibit any steps in diameter.
• The probe must be 100 mm longer than the lower disposal.
• Within the measuring range, the probe must not get into contact with the pipe wall. If
necessary, use a center washer (see feature 610 of the product structure).
• If the center washer is mounted at the end of the probe, it enables a reliable recognition of the
end-of-probe signal (see feature 610 of the product structure).
Note: For interface measurements only use the nonmetallic center washers made of PEEK or
PFA (feature 610, options OD or OE) (® ä 96).
• Coax probes can always be applied if there is enough mounting space.
