Rice Lake CW-90 Checkweigh Indicator EU Legal for Trade Weight Controller

Rice Lake CW-90 Checkweigh Indicator – EU Legal for Trade Certified

The Rice Lake CW-90 Checkweigh Indicator is a high-performance digital weight indicator engineered for checkweighing, quality control, packaging, food processing, warehouse, and industrial weighing applications. Designed with rugged stainless-steel construction and advanced data collection capabilities, the CW-90 provides reliable performance in demanding environments while meeting European Legal for Trade requirements.

Recognized as the bench checkweigher of choice, the CW-90 combines ease of operation, real-time data collection, and durable IP66-rated protection. The front-panel configuration menu allows users to access settings directly from the keypad without opening the enclosure, helping protect the indicator from moisture, contaminants, and harsh operating conditions.

The indicator stores detailed information for up to 50 IDs, making it easy to manage multiple products, batches, or weighing applications. A large six-digit high-intensity red LED display provides excellent visibility, while over/under checkweighing functions help operators maintain product consistency and compliance with quality standards.

The CW-90 supports up to eight 350-ohm load cells or sixteen 700-ohm load cells and offers flexible communication options including dual RS-232 serial ports with optional Ethernet, USB, and fiber-optic connectivity. Advanced audit trail tracking, accumulator functions, configurable print formats, and digital I/O capabilities make it ideal for process control and production monitoring applications.
