Product Details

WST1202 RS485 RS232 digital output Parallel beam 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 RS232 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 conventional price-computing scales, counting scales, weighing scales, retail scales, and platform scales, but is also widely used in various smart IoT products, such as smart shelves, vending machines, and RVM (Recycling Management System) automatic recycling equipment.

FEATURES

Aluminum alloy,surface anodized and anticorrosion;

Built-in digital module, digital signal output, RS485 or RS232;

Max platform size: 400×400mm;

Factory calibration, no calibration required

Modify the acceleration of gravity and can be used in other places without calibration;

To change division value, after that, the corresponding weight can be output, no need for field calibration;

The sensor has only one zero-setting command and a weight read command are immediately accessed;

Mainly used in smart shelves, smart gravity cabinets, garbage recycling and others.
