Rice Lake Master BS211 Belt Scale System

Belt Scale Systems

We proudly supply the Rice Lake Master Series 211 precision belt scale system that consists of an inner frame mounted with two friction-free pivots to one end of the scale. The load cell is located on the opposite end with the idler mounted on the inner frame. Therefore, the friction-free pivots absorb tensile stress in a horizontal direction. This creates a very solid weigh frame that is well-suited for heavy-duty applications that you can trust.

The BS211 is designed to monitor feed to crushers, mills, screens and other processes as well as regulate product loadout with an accuracy up to ±0.5%.


  • Medium to Heavy Capacity, mining, process and agriculture
  • Chemical plants, Asphalt plants, Mines, Cement mills, Coal preparation plants
  • Paper mills, Gypsum mills, Sand and gravel operations
  • Coal-fired power plants
  • Ore beneficiation processes

Discover the Rice Lake Master Precision Belt Scale for time proven heavy-duty design that is perfect for challenging applications. The intuitive Integrator makes set-up and calibration, with on-board diagnostics, easy to use. Contact our Sales team today.

Rice Lake Master Belt Scale Weigh Frame

Belt Scale Weigh Frame BS221DB

We proudly supply 221DB Master™ belt scale weigh frame manufactured by Rice Lake Master. This frame consists of two arms that are equipped with a pivot and a load cell mounted to the side supports of the conveyer belt. The idler, or weighing roller, is mounted on top of the frame arms.

The 221DB is easy to assemble and access to service. Being suitable for most belt widths and capacities, the 221DB is a versatile solution for many applications with an accuracy of ±0.5% to 1.0%, even in the harshest applications.

This belt scale weigh frame enables you to monitor production output and inventory, or regulate product loadout, while providing vital information for the effective management and efficient operation of your business.

Ramsey Mercury-Free Tilt Sensor
Ramsey Mercury-Free Tilt Sensor

Thermo Scientific Ramsey Mercury-Free Tilt Sensor

The Thermo Scientific™ Ramsey™ Mercury-Free Tilt Sensor is a rugged, abrasion-resistant solution for the detection of materials handling problems. Actuated when materials rise to tilt the probe by 15o or more, in any direction, it replicates the performance of traditional mercury-based technology while simultaneously reducing health and safety concerns. Measurements are jitter-free, stable, and highly sensitive. Choose from a variety of probe assemblies to match specific process materials and environmental conditions – including options for use in hazardous areas – to efficiently detect problems such as high and low level, chute blockage, and sub-optimal material flow.

Thermo Scientific Ramsey C-Level

Eliminate failure and maintenance issues with your inventory monitoring and process control system with the Thermo Scientific™ Ramsey™ C-Level Continuous Level Indicator. Ideally suited for bulk solids or liquids, the Ramsey C-Level Continuous Level Indicator monitors inventory and process control during load-out or filling. With its unique precision strain gauge sensors press-fit into the support structure, the Ramsey C-Level Continuous Level Indicator can operate without concern for failure or maintenance issues caused by the monitored material or process environment. This distinctive design also compensates for temperature changes that can affect the accuracy of bolt-on strain sensors.
