Continuous Measurements

Standley RD30-US Radar Level Transmitter

Guesswork has no place in a concrete plant. When you can’t see what’s happening inside your silos, you’re one bad read away from a run-out, an overfill, or a shutdown you didn’t see coming.

The Standley RD30-US radar level transmitter gives you continuous, non-contact level measurement built for the dust, buildup, and rough conditions of daily plant operation. It’s the newest addition to our lineup of silo protection and level monitoring systems.

• Accurate to within 0.08″ (±2 mm), with resolution down to 0.04″ (1 mm)
• Reliable readings in dusty cement silos, aggregate bins, and other tough storage vessels — 80 GHz FMCW radar cuts through dust and buildup that trip up older sensors
• Non-contact measurement means no wear parts, no recalibration, and no manual checks climbing silos
• Rugged IP68 housing and PVDF wetted parts built to stand up to corrosive materials
• Wireless Connectivity via Bluetooth® Low Energy 5.2

Standley Batch has spent more than 80 years designing and building the systems that keep concrete plants running. The RD30-US was selected and configured for the environments our customers actually work in — narrow cement silos, dusty aggregate bins, and vessels packed with ladders, mixers, and other structure that trips up ordinary radar.

With a beam angle as narrow as 4°, the RD30-US delivers precise readings even in tall, slender silos or tanks with internal obstructions.

Built for the vessels you already run:

• Cement and fly ash silos
• Aggregate and sand storage bins
• Admixture and additive tanks
•  Water reservoirs and batchers
• Mixed product and blending hoppers

The RD30-US installs as a standalone level transmitter or as part of a complete Hycontrol SHIELD Lite Silo Protection System — giving your team the data they need to plan ahead, avoid run-outs, and cut down on manual checks.

Radar

For demanding applications with powders in very dusty atmospheres, the RD Series two-wire 80 GHz FMCW radar level transmitter is an ideal choice. With its small beam angle, this radar indicator is particularly suited for continuous, non-contact level measurement in high and narrow silos, hoppers or buffer storage containers up to 328 ft. In addition, due to the high signal dynamics of the FMCW radar, the level transmitter is ideal for low-reflective media, dust, uneven surfaces or complex silo internal structures. Furthermore, as it features a flush-mounted PEEK Lens antenna, there is no intrusion of the antenna into the silo, bin or hopper. Standard 3″ NPT fitting.
