Selection

Different membranes should be used depending on the special characteristics of the bulk materials used. The weaker and less abrasion-resistant membranes are naturally somewhat more sensitive. They are particularly appropriate

  • for bulk materials with particularly low specific weight,
  • or in small containers.
The correct choice of the installation point is also very important.

Theavailable membranes are:
Material use for
Perbunan 0,5 mm (PB 05) or
Perbunan 1,0 mm (PB 10)
powdered materials with low specific weight: grime, chalk, PVC granulates, food (milk powder, flour, cocoa), semolina, rolled oats, rice, sugar, cacao beans, leguminous plants, salt, coffee, grain and bulk materials of similar structure
Viton 0,5 mm (VT 05) or
Viton 1,0 mm (VT 10)
powdered bulk materials at higher temperatures. Moreover for: Cement, gypsum, fertilizer, dry sand, gravel and filling materials with stronger abrasion.

Membrane characteristics:
Type of membrane for indicator type Device Sensitivity Abrasion resistance Food Temp. range in °C fat constancy
PB 05 FMK 508 very high average yes -30 to +100 good
PB 10 FMN 113 very high average yes -30 to +100 good
VT 05 FMK 508 high very high no -30 to +150 very good
VT 10 FMN 113 high very high no -30 to +150 very good

Always choose the larger level indicator type

  • for bulk materials with greater grain size and stronger internal friction,
  • if the bulk materials tend to form crusts or bridges.

Attention! These level indicators are only conditionally suitable

  • for materials that strongly form crusts,
  • for materials with high internal friction (e.g. coke of larger granulation)
