BCi Belt Scale Weigh Frame

Rice Lake Weighing Systems ·

Up to 20,000,000 lbs

Accuracy: 0.5% (two-idler) to 1% (single idler)

Rice Lake's BCi belt scale weigh frame is extremely accurate and durable for process control and load-out applications. It can process up to 10,000 tons per hour with a maximum belt speed of 1,200 feet per minute. Four laterally opposed shear beam load cells are mounted in a unitized idler frame, which compensates for torque load and speed changes. The system achieves 1% accuracy with a single idler and 0.5% with a two-idler configuration.

Master 14X Belt Scale Weigh Frame

Rice Lake Weighing Systems ·

Up to 40,000,000 lbs

Accuracy: 0.25%

The 14X Master belt scale weigh frame weighs three idlers on an inner frame, supported by four load cells. This design creates an incredibly accurate belt scale qualified for high capacities and belt speeds. The frame is custom-made using conveyor specifications, making it suitable for different belt conveyor models. It is often used in mining and aggregate applications.

Master 211 Belt Scale Weigh Frame

Rice Lake Weighing Systems ·

Up to 6,000,000 lbs

Accuracy: 0.5%

The 211 Master belt scale weigh frame 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. The friction-free pivots absorb tensile stress in a horizontal direction, creating a very solid weigh frame well-suited for heavy-duty applications.

Master 221DB Belt Scale Weigh Frame

Rice Lake Weighing Systems ·

Up to 6,600,000 lbs

Accuracy: 0.5% to 1%

The 221DB Master belt scale weigh frame consists of two arms equipped with a pivot and a load cell mounted to the side supports of the conveyor belt. The idler, or weighing roller, is mounted on top of the frame arms. The 221DB provides simple assembly and accessibility for service. Suitable for most belt widths and capacities, the 221DB is a versatile solution for many applications.

Master 311 Belt Scale Weigh Frame

Rice Lake Weighing Systems ·

Up to 3,000,000 lbs

Accuracy: 1%

The 311M Master belt scale weigh frame consists of an idler or weighing roller positioned on a simple load cell beam, providing a cost-effective weighing solution. It accommodates belt widths up to 1,500 mm and belt speeds up to 2 meters per second. The frame is commonly used for belts that regulate bulk flow capacity using the measured value and controlled belt speed. The design features semi-modular construction without moving parts and requires weigh frame cutting for proper fit with minimal conveyor modifications.

Master 421 Belt Scale Weigh Frame

Rice Lake Weighing Systems ·

Up to 60,000 lbs

Accuracy: 1.0%

The 421 Master belt scale weigh frame is specifically designed for high volume, low-density applications where belt load and belt speed are moderate. Ideal for flat belt conveyors, the 421 features two BM11 bending beams and hermetically sealed load cells mounted to adjusting plates on the outside of the conveyor stringers to create a stable base. The 421 master belt scale is also available for hazardous and explosive areas.

SCT-4XD Integrator

Rice Lake Weighing Systems ·

Accuracy: 0.3 uV/graduation minimum signal sensitivity

The SCT-4XD is a multi-channel weight transmitter with Belt Scale Integrator firmware designed for bulk material weighing applications. It manages up to four load cells for a single scale and features dual encoders with automatic test weight application capabilities. The device includes a micro-USB communication port enabling configuration, diagnostics, and data backup through RL Tools Software. All scale data and adjustments integrate with fieldbus systems. The unit provides a power supply circuit with industrial-grade protections and removable terminal blocks for simplified panel wiring.

Speed Sensor

Rice Lake Weighing Systems ·

Accuracy:

The speed sensor monitors belt speed. It is directly coupled to a rotating shaft which drives a signal generator. The speed sensor submits an output signal at a frequency directly proportional to the shaft speed. It is typically installed on a non-driven pulley of a belt conveyor for detecting belt speed. Available in generator type and encoder type variants.
