Ultra Compact Weigh Module for Fast In-Process Tablet Testing

METTLER TOLEDO’s ultra compact weigh module is ideal for use in weighing applications where installation space is extremely limited.

Fast and easy to integrate into machines, its 25mm width minimises the space needed for an in-process quality control device.

In-process weight control of 100% of the output of a tablet pressing machine is a real challenge. These machines run at very high speed, producing tens of thousands of tablets per hour. Quality control of each tablet is only possible if distances between individual process steps are short. Plus the mechanical pressing process generates noise, vibrations and dust, adding further complications.

The WMC weigh module is designed to cope with these challenges. It has a weighing capacity of 20g and a readability of 0.00001g. The weigh module can be allocated in rows to weigh lots of tablets in parallel. Its very small width reduces the distance between weigh modules and helps to keep overall dimensions of the test device to a minimum. The short weighing time per tablet, as little as 0.3 seconds, enables the check weighing process to keep the pace of the tablet press. The filter algorithms ensure the measuring of correct and repeatable results in spite of vibrations from the machine.

The robust stainless steel design with built in overload protection guarantees high precision weighing performance in an industrial environment. It is equipped with a fast RS232 interface for high speed data processing. The module has options to communicate with PLC systems via DeviceNet™, Profibus®, ControlNet™ or EtherNet/IP™.
