Capsule checkweigher CW-150

tabletfor the pharmaceutical industryonline

Overview
The CW-150 is an in-line checkweigher engineered for pharmaceutical production lines to measure the individual weight of every tablet or capsule. It inspects up to 150,000 objects per hour and rejects non-compliant units, providing 100% weight control suitable for products up to OEB3 containment levels. The system can operate in-line for Real Time Decision (RTD) workflows or off-line for batch recovery inspection.

Key benefits

• 100% weight control of tablets and capsules
• Accuracy ±1 mg (3 Sigma)
• Upgradeable to 100% Content Uniformity weight + % APIs
• Up to 150,000 objects/h
• Single-line system — reduced maintenance and calibration time
• Fast and easy format change-over
• Suitable for ≤ OEB3 containment

Embedded technologies
At the core of the CW-150 is a 3D microwave resonator that provides ultra-precise, non-contact electromagnetic mass measurement. This method delivers fast and repeatable weight readings within tight error boundaries and has been validated through multiple industrial test campaigns and repeatability studies.

The unit integrates a calibration protocol based on multiple linear regression. For calibration reference, products are routed to a high-precision weigh cell located in a sealed chamber. Optionally, the chamber can host a 4-parameter tester to measure weight, hardness, thickness and diameter for additional offline QC sampling.

User management & integration
All measurement data are processed by high-speed processors and stored in CFR21 Part 11–compliant software with a step-by-step user interface. The system supports USB export and OPC UA communication for seamless integration with MES, PAT or other upstream/downstream equipment.

Practical use & compliance
Designed for ease of use in pharmaceutical production, the CW-150 permits rapid, cost-effective format changes across tablet and capsule sizes. It conforms to CE directives and is supplied with user manual, safety instructions and wiring diagrams. Simplified mechanics reduce routine maintenance time, making it suitable for daily production environments.
