The RBSS speed sensor is a continuous weighing speed sensor used in conjunction with a belt scale. It monitors the speed of the conveyor belt and provides a signal to the integrator to calculate the flow rate of the material. It features a sturdy design, easy installation, low cost, and accurate belt speed detection.
This manual describes the RBSS speed return sensor (model RBSS 34) produced by Siemens. It covers the sensor's operating principles, wiring options and installation guidelines.
Key technical data such as voltage supply, current limits, temperature range, frequency and speed ranges, cable lengths, protection rating (IP65) and certifications (ATEX II 2G EEx ia IIC T6, CSA/FM) are listed for both the RBSS and RBSS IS variants. This manual is written in Chinese.
