Thru-Wall Level Switches GPLS-25, Dinel-Level and Flow Measurement

Through the wall, level switches GPLS–25 is intended for liquid (conductive and non-conductive) level detection on glass or plastic gauge-pipes, tubes, and tanks. The sensitivity and modes (SO – normally open or SC – normally closed) of the switches can be easily set by placing a magnetic pen on a sensitive spot. The connection is done using two wires directly into a circuit with a relay or to binary input of the control system.

Features

• For liquids limit level sensing on non-conductive (glass or plastic) gauge-pipes, tubes, and tank walls
• The sensor is equipped with high-frequency technology, which allows reliable operation even for sensing of the adherent electrically conductive medium
• Miniature performance in a plastic housing, LED state indication
• Simple sensitivity setting using a magnetic pen
• Variants with a fixed cable or a connector
• Two-wire connection directly to the relay circuit or PLC input

Features of Variants

• GPLS–25N–
  0 Prismatic (refracted) electrode, shape-adapted to be attached to the gauging pipe or other tubes. The
  fixing of the sensor onto a pipe is provided by plastic straps.
• GPLS–25N–
  1 Planar electrode, suitable for installation on flat surfaces (e.g. plastic or glass tanks). The sensor
  can be fixed with plastic straps or by a double-sided adhesive layer.
