The BSUB Base Unit for BS, designed by EDIBON, is the central hub of a modular sensor and instrumentation training system. It provides signal conditioning for a wide range of sensor and transducer outputs — including potentiometers, RTDs, thermocouples, and strain gauge bridges — through circuits such as differential and instrumentation amplifiers, filters, and current-to-voltage and frequency-to-voltage converters. The unit also includes a PID controller, industrial controller, and DC dimmer, giving students hands-on exposure to the fundamentals of process control. The BSUB connects to any of the BS series test modules — covering temperature, pressure, flow, vibration, and more — and can operate with one module or several simultaneously, making it a scalable foundation for building out a comprehensive sensors and instrumentation lab.
