DP130 Diamond Point

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.

The DP Series from Hycontrol all operate on this principle; all share the diamond-shaped probe design which prevents product accumulation and promotes self-cleaning. This product family has several variants to allow for precise matching to each individual application.

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 therefore 2 metres.

The DP130 is suitable for top or angular mounting. Refer to the data sheet in the links below for more information.
