Siemens TM SIWAREX WP351 HF Weighing Electronics is a compact and highly accurate weighing module designed in the SIMATIC ET 200SP format. Measuring only 20 mm in width, it stands out as one of the most slender weighing modules available. Its firmware incorporates the functionalities of an automatic totalizing weighing instrument, as well as the capabilities for checking, bagging, and filling scales. All operational modes are integrated into the firmware and are certified according to OIML standards R-51, R-61, R-76, and R-107. This certification enables the WP351 to be employed in scales that require official calibration, as well as in applications where there are stringent demands on speed and precision, even without calibration.
