Temperature pressure transmitter SMC

CAN bus sensor: Transmitter for pressure and temperature A CANopen sensor is a modern measuring device that can record physical quantities such as pressure or temperature and transmit them digitally via the CANopen standard. The CAN bus technology is based on the international ISO standard 11898 and enables the fast and interference-free transmission of measurement data. CANopen itself is a globally standardized transmission protocol that enables unified and easy access to measurement data by using standardized device profiles. The certification of the CANopen protocol ensures the compatibility of our sensors with other CANopen controllers and facilitates the integration of the pressure transmitters into existing systems. How a CANopen sensor works A modern CANopen sensor uses digital measurement data transmission to ensure high resolution of the data. First, the analog measured value is recorded by the sensor and converted into digital data. In this digital range, errors are corrected by linearization and temperature compensation, making a precise and stable measurement possible. This is followed by direct transmission via the CAN bus – this avoids conversion losses. The high transmission rate of up to 1 Mbit/s enables fast data transmission in millisecond intervals and ensures precise control and control of your processes.
