KOBOLD Instruments, Inc. NMF - Level Switch for Bulk Media

Product Features Handles a Wide Range of Dry Bulk Goods Mechanically Actuated Switch Requires No Power to Operate Economical Media Temperatures to 390°F Easy to install For Thick or Thin Walled Vessels KOBOLD NMF membrane switches allow level monitoring of dry bulk goods in storage vessels. These are commonly used to indicate full and empty conditions for powdered and granular bulk materials. Any free-flowing material with a grain size up to 30 mm (~1.2 inches) and having a density within the limits of 19-144 lb/ft3 is suitable for use with the NMF. The NMF is a simple, pressure sensitive device with the material pressure transmitted to an internal mechanical switch via an elastomer or thin metal membrane. Operation is simple and very reliable if the material is not sharp-edged or not placed directly into the bulk fill stream. However, even these types of situations can often be accommodated by the use of simple mechanical shielding to protect the diaphragm.
