Vibrating Solids

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, 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 65 feet of 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).

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,

Why choose vibrating probes for safety systems?

The DP Series diamond point level switch is designed specifically for use with dry products ranging from heavy materials such as stone, aggregates, and ready-mix cement, to very low-density materials like fly ash, cornflakes, and flour. Its unique principle of operation and shape ensure that it is self-cleaning. Because this solids level indicator is only sensitive near its tip, it will not be affected by any build-up of product on the storage vessel walls. This immunity is helpful in the reduction of false trip alarms.

Hycontrol’s diamond-shaped vibrating blade is unique in both design and construction. It is highly reliable and, thanks to its vibrating action and unique shape, it has a self-cleaning action that prevents the build-up of falling media along the sensing blade. If mounted in a horizontal position, it will sense a rising surface only when it makes contact at the probe tip. The cleverly-engineered internal structure of the blade gives the probe greater strength and stability, helping to prevent premature failure through bending or damage, as well as ensuring more accurate readings.

With minimum maintenance requirements and a strong track record of success, the DP120 is an excellent choice for solids point switching applications. Furthermore, the probe is fully Ground Level Test-enabled, providing users with guarantees of functionality and reducing working at height requirements.
