Ultra-compact weighing electronics for maximum precision
Siwarex WP351 is Siemens’ newest solution for intelligent weighing automation. Measuring 20 millimeters
width by 65 millimeters height, the module is one of the smallest weighing electronics units available.
The device’s 1,000 Hz sampling rate and processing time combined with a digital output response time of less
than one millisecond guarantee highest accuracy and repeatability.
This capability represents especially in case of checking scales and high-performance filling machines a big advantage, as even within very short weighing times the dosing devices are controlled in an optimal way. As an integral part of Simatic ET 200SP, Siwarex WP351 can be seamlessly integrated into Simatic and non-Simatic automation systems, making it a clever alternative to traditional weighing terminals.
The intelligent firmware gives users the ability to control weighing processes directly from the module, thereby reducing the load on the connected PLC.
