Digital parallel beam load cell
FEATURES
- Aluminum alloy,surface anodized and anticorrosion;
- Built-in digital module, digital signal output, RS485 or RS232; Max platform size: 400×500mm;
- 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.
