Checkweigher Station

VISIOTT's Pharmaceutical Checkweigher Station

Checkweigher systems are used in the pharmaceutical industry to ensure total quality and patient safety. Therefore, the precision and operational accuracy of its weight measurement must be perfect. Besides, a pharmaceutical checkweigher system used in the industry must be designed following many standards such as GMP, GAMP 5, and CFR 21 Part 11. VISIOTT’s checkweigher stations are innovative solutions designed to meet all the operational requirements of pharmaceutical manufacturing.

Most Popular Pharmaceutical Checkweigher Applications

  • Detection of missing components in cartons (prospectus, blister, spoon, syringe, etc.).
  • Detection and rejection of drugs manufactured as sachets on the production line.
  • Filling lines such as powder and semi-solid, where the dosing process can make mistakes, are controlled with feedback/tendency information and filled with the correct amount.
  • Quantity controls of volatile products such as aerosols after the quarantine period.

VISIOTT’s pharmaceutical checkweigher stations can be easily added to automatic or manual drug manufacturing operations. Furthermore, our pharmaceutical checkweigher stations, which have high repeatability values and can measure the weight of 300 cartons per minute, guarantee drug safety with a wide range of reject methods.

Unlimited Design

Thanks to the integrated industrial Intel-based computer system, there is no hardware and speed limit for changes specific to operations.


Validation and revalidation of the checkweigher system can be performed with GAMP5 compatible documents delivered together with the system.

Service Support

It guarantees the continuity of production processes with 24/7 remote and on-site assistance support service.

Precise and Accurate Weighing

It can be measured with an accuracy of 0.01 g (10 mg). Then, these values are directed to the feedback port for filling calibration of the packaging machine.


The conveyor lengths and also guidelines of the system can be quickly redesigned according to the operational requirements.

Fast and Accurate

Developed measurement algorithms for the most accurate and precise result at each speed value are developed specifically for the operation with a team of experts.

You can find detailed information about our pharmaceutical industry-focused checkweigher stations in the following tables and drawings or catalogs. Besides, you can test the system with your products by making an appointment at our demo centers in Ankara and Istanbul. Moreover, please feel free to contact our sales team for more detailed information.

Correct Checkweigher Implementation for Phamaceutical Cartons

Firstly, Checkweigher systems must be placed behind the cartoning machine on such lines. Secondly, it must be mechanically adjusted that each carton that comes out of the cartoning machine is left to the infeed conveyor of the system without falling too hard. Besides, care must be taken to maintain the linear flow of the cartons as they pass from the feeding conveyor to the measuring conveyor. Thirdly, and most importantly, it must be noted that there is always a product on the measuring conveyor. Also, speed and product length synchronization must be followed intently. Finally, the reject method to be used during the separation of the products with unsuitable weight from the outfeed conveyor must be designed and placed in a way that does not affect the measurement sensitivity.
