1 Product description 1 Product description 1.1 Overview If VEGAFLEX sensors with rod or cable version are used in standpipes or bypass tubes, contact with the tube wall must be reliably avoided. Spacers or centering weights fix the measuring probe in the middle of the tube. Use as few spacers as possible. With rod probes, one spacer at the probe end is usually sufficient. Spacers - Plastic (K) Spacers of plastic are suitable for applications up to 250° C (482° F).

2 Mounting 2 Spacers Mounting 2.1 General instructions Use as few spacers as possible. With rod probes, one spacer at the probe end is usually sufficient. If several spacers are required, they should be mounted large distances apart. Buildup Keep in mind that buildup can form on the spacers. Strong buildup can influence the measurement. Standpipes or bypass tubes When probes are used in standpipes or bypass tubes, contact with the tube wall must be avoided.

Measure the diameter of the standpipe or bypass tube and adapt the spacers accordingly. The notches on the 4-arm spacer allow simple trimming down to tube diameters DN 50 (2") and DN 80 (3"). For cutting, use a metal saw or a pair of strong pincers or side cutters. 2. The spacer should be mounted at the lower end of the probe rod.
2 Mounting The retaining rings fix the spacer in the desired position. A certain clearance is permitted. Note: The retaining rings can be moved only in one direction. If you have already passed the desired position, cut the retaining ring with a side cutter. Use a new retaining ring. 2.3 Spacers - Plastic (open on the side) (K4, K5) 1 Fig. 9: Mounting the spacer (open on the side) 1 Spacer (K4, K5) for tube inside diameter ≤ 100 mm (4") 1.
2 Mounting Note: The spacer may not be moved in the axial direction. The insulation of the cable or rod could be damaged. You can remove the spacer laterally and attach it again at another position. 2.4 Spacers - Metal (M1, M2, M3, M4) 2 1 2 Fig. 10: Mounting the spacer 1 2 Spacer (M1, M2, M3, M4) M1, M3 - outer ø 49.2 up to 56.3 mm (1.9 up to 2.2 in) M2, M4 - outer ø 66.6 up to 84.9 mm (2.6 up to 3.3 in) Retaining ring 1.
