Overview
The MK-DBSQ-02 is a weighing transmitter module that conditions the signal from a strain-gauge load cell and reports the weight over a standard Modbus RTU network. It is designed to pair with any Wheatstone-bridge resistive strain-gauge sensor, which simplifies retrofits and spare-part standardisation.
Key Features
- Standard Modbus RTU digital output
- Works with any Wheatstone strain-gauge sensor
- Sealed to Optocoupler isolation, power isolation, surge protection (not on basic version) for reliable operation in harsh environments
- Compact design for straightforward integration
Applications
Suits integrators adding analogue load cells to Modbus-based PLC, SCADA or gateway weighing systems in batching, hopper and platform duties.
