The DP Series Diamond Point level switches from Hycontrol are a family of vibrating probes for use with dry products, ranging from heavy materials such as stone, aggregates and cement, to very low-density materials like cornflakes and flour.
The blade is oscillated by a piezoelectric crystal, meaning there are no mechanical parts to wear out. This unique principle of operation, combined with the special diamond shape, ensures that it is self-cleaning. Additionally, because it is only sensitive near the probe tip, it is not influenced by build-up on the silo walls.
A very popular choice in level switching and safety system applications, the DP150 can be supplied with up to 20 metres of a polyurethane sheathed, steel rope reinforced cable.
The DP150 is for top mounting only. The connection to the container is made by thread 1½” DIN or NPT. The DP150 has the advantage of offering very long insertion lengths but also provides easy transport as it can be shipped in very compact boxes (particularly when compared to the extension tube models DP130 and DP140).
The DP150 can be used for the detection of solids or for the detection of sediment below the liquid level.
It is ideal for ultimate high-level alarm safety, and for this reason, it is also used as an integral component in Hycontrol's SHIELD silo protection system.
