A digital bus pressure transmitter is a smart sensor that converts pressure signals into digital communication data. It supports industrial protocols such as CANopen or Modbus RS485, enabling direct integration with PLCs and industrial IoT systems for remote monitoring and data transmission.
CANopen is a high-speed real-time fieldbus protocol suitable for complex multi-node control systems, while RS485 (Modbus RTU) is better for long-distance, cost-effective networking. Both are used for industrial pressure monitoring but differ in communication architecture.
They are widely used in construction machinery, heavy-duty trucks, hydraulic systems, wind power equipment, automation production lines, and industrial IoT systems, especially where multi-device networking and remote monitoring are required.
A CAN bus pressure sensor transmits pressure data in digital message format via the CANopen protocol to a controller or PLC, supporting multi-node synchronous communication for higher real-time performance and reliability.
RS485 Modbus pressure transmitters offer strong anti-interference capability, long transmission distance, low cost, and easy networking, making them ideal for distributed industrial monitoring systems.
Yes. Both CANopen and Modbus RS485 protocols support multi-node networking, allowing multiple pressure sensors to be connected in a single communication network for centralized monitoring and data acquisition.
