WST1206 Canbus or RS485 output signal digital single point load cell, Compared to analog sensors, this series of digital sensors primarily integrates a digital transmitter, allowing the load cells to directly output standard RS485 or Canbus digital signals. Each sensor boasts high precision and high resolution, requires no additional calibration, and can be directly used with downstream equipment.
Since eccentric load compensation is pre-installed at the factory (compliant with OIML R60 standard), installation is quick; a single sensor is sufficient to build a complete scale.
This series of sensors can be used not only in stainless steel waterproof scales, process weighing control in the chemical, food and pharmaceutical industries., but is also widely used in various smart IoT products, such as smart shelves, vending machines, and RVM (Recycling Management System) automatic recycling equipment.
