GPB100D Smart Digital Single Point Load Cell

The GPB100D is an intelligent digital load cell specifically optimized for the IoT retail and smart recycling industry. By integrating high-precision A/D conversion directly within the sensor, it outputs standard RS232 /RS485 Modbus RTU signals. This eliminates the need for external weighing indicators, simplifies multi-sensor bus networking, and provides robust anti-interference performance in complex smart hardware environments.

Frequently Asked Questions

1. Can I connect multiple GPB100D sensors to a single controller?

Yes. Using the RS485 Modbus RTU protocol, you can assign a unique slave ID to each GPB100D, allowing you to monitor dozens of shelves or cabinet slots through just one bus line.

2. Why is a digital load cell better for smart retail than an analog one?

Smart retail environments often have significant electrical noise from refrigerators or motors. GPB100D's digital output is immune to this noise, ensuring stable inventory data without requiring high-cost shielded cabling.

3. Does the GPB100D require an external weighing transmitter?

No. The GML100D has a built-in A/D converter and transmitter. It outputs weight data directly in digital format, which can be read by a PLC, PC, or micro-controller.

4. What is the communication distance for the RS485 bus?

The GPB100D can reliably transmit digital data over the RS485 bus for distances up to 1000 meters, far exceeding the limits of traditional analog weighing cables.

5. Do you provide technical support for Modbus integration?

Yes. We provide complete Modbus address mapping and technical protocols to help your software team integrate the sensor quickly into your smart shelf or cabinet system.
