The DP Series diamond point level switches from Hycontrol are a family of vibrating probes for dry products, ranging from heavy materials such as stone, aggregates, GGBS and ready-mix cement to very low-density materials like cornflakes, ash, lime, fly-ash 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 or along the cable.

A prevalent choice in level switching, silo protection and safety system applications, the DP250 can be supplied with up to 20 metres of a polyurethane sheathed, steel rope reinforced cable.

The DP250 is for top mounting only. The probe connects to the container by a 1½“ DIN or NPT thread. The DP250 offers very long insertion lengths, which can be adjusted if required using simple cable ties. Besides this, it also allows for easy transport and storage as it can ship in a more compact box (particularly when compared to the extension tube models DP230 and DP240).

The DP250 detects solids levels or can detect sediment below a liquid level.

It is ideal for ultimate high-level alarm safety, which is also an integrated component in Hycontrol’s SHIELD Lite silo protection system. Besides its self-cleaning action, the switch is fully Ground Level Test-enabled, making it the most reliable switch for high-level alarm applications on powdered and solid products.
