DP130 Vibrating Diamond Point Level Switch

Level switches for solids

The operating principle for all vibrating probe level switches relies on a piezoelectric crystal, used to force a blade to oscillate at its fundamental frequency (sometimes also referred to as the natural resonance). When the blades come into contact with the process medium the natural frequency of oscillation is dampened; the electronics sense the change in frequency which causes the unit to switch.

If the application requires a longer insertion, the DP130 offers the possibility to adapt the insertion length exactly to the length required by means of a pipe which is welded between the vibrating probe and the 1½” mounting socket. The maximum insertion length for the DP130 is 2 metres. The DP130 is suitable for top mounting.
