Ultra-compact weighing electronics for precision

| By Chemical Engineering

Siemens Digital Industries

The Siwarex WP351 (photo) is one of the smallest electronic weighing units available, measuring just 20 mm (width) by 65 mm (height). The device’s 1,000-Hz sampling rate and processing time, combined with a digital output response time of less than 1 ms, guarantee high accuracy and repeatability. This capability is especially advantageous for checking scales and high-performance filling machines, as even within very short weighing times, the dosing devices are optimally controlled. As an integral part of Simatic ET 200SP, Siwarex WP351 can be seamlessly integrated into Simatic and non-Simatic automation systems. The intelligent firmware gives users the ability to control weighing processes directly from the module, thereby reducing the load on the connected programmable logic controller (PLC). — Siemens Digital Industries, Nuremberg, Germany
