DP250 Diamond Point

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,

DP220 Diamond Point

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.

MWS Blocked Chute Detector

The Hycontrol MWS microwave-blocked chute detection system provides a simple non-contact, non-intrusive option suitable for many applications on dry powder or granular products.

An installation comprises a transmitter and a receiver which are mounted facing one another at distances up to 100 m apart (for the AC version). During operation, the transmitter emits a continuous, low-power microwave beam to the receiver, and an output relay is energized or de-energized when the monitored material obstructs the beam.

The amount of microwave energy received determines the switch trigger point. Therefore, the MWS can be adjusted to cater to different products and sensitivity settings depending on the application. Typical applications for detecting the presence and non-presence of materials include flow and no-flow conditions, point level detection, blocked chute detection, and proximity switch detection for reversing vehicles, including trucks and rail cars.

This technology can monitor product build-up on tank or chute walls and can be non-intrusive by utilizing protective windows. It is ideal for replacing costly nucleonic devices – unlike which there are no requirements for permits or special operator training. It is easy to retrofit existing chutes and vessels. The MWS system has very low maintenance requirements.

Microsense Flow Switch

Hycontrol’s Microsense flow/no-flow detector offers a safe and straightforward solution to various production applications. When applied to solids, powder or particulate products, the single-piece, non-contact unit alerts operators to disrupted flow where continued supply is required (perhaps caused by a blockage or loss of supply). Conversely, it can confirm flow has stopped entirely before new material is introduced into the flow stream, eliminating the risk of cross-contamination.

The flow switch uses a microwave Doppler effect and is non-invasive. During operation, the sensing head transmits a continuous low-power microwave beam onto the path of the flowing product. As a result, any present product will partially reflect the microwave beams. Analysis of these reflections will show whether the product particles are moving or stationary objects.

The highly penetrative microwave beam emitted by the Microsense unit passes through any build-up on the transmitter face. It will even detect through pipes of non-conducting materials such as plastic and ceramics. This versatile and powerful switch is best suited for detecting materials such as dry solids, granules, flakes, and powders. Microsense is sensitive enough to register low levels of flow. By ensuring operators are fully aware of their flow or no-flow status, the unit assists in the achievement of relevant hygiene standards, confirming there are no contaminants from other material streams present.

Typical applications include grain, flour, cement, ore, stone coal and animal feed mills. Microsense will detect flow in pipelines, chutes, transfer bins, distributors, feeders, conveyor belts, bucket elevators or free air. For extra security, this detector can combine with a microwave blocked chute monitoring system to provide both flow or no-flow output and blocked or clear chute indication, providing operators with maximum plant protection.
