Indicator tube and cover:
U-rail: Aluminum, anodized, natural color
End pieces: Technopolymer plastic (Polyamide PA), matte black
screw: Steel, zinc-plated, blue passivated
O-ring: NBR rubber (Perbunan)
Due to the U-rail and cover, Elesa®
design EN 654 fluid level indicators are extremely stable and therefore suitable for long lengths. The fluid level can also be viewed from the side.
Temperature resistant to 212°F (100°C), resistant to alcohol but not solvents.
For special requirements of chemical, pressure,and temperature resistance, please contact us.
Other l1 lengths, temperature display, and electrical temperature monitoring available upon request.
||Installation of EN 654 oil level indicators is very simple and economical. You need to drill two Ø 10.5 or Ø 12.5 mm (depending upon "d" thread) holes in the container wall, l1 center to center distance apart.
Oil level indicator can also be installed directly,
i.e. without nuts, if the container wall has a mounting thread.
All individual parts necessary for the assembly are provided, including
hex nuts, O-rings and serrated lock washers.
For a perfect seal using the O-rings, the screws should not be too
strongly tightened (max. 12 Nm). Recommended roughness of the sealing surface is RA = 3 μm.
