The trainer aims to practise the use and practical handling of industrial components that are connected using a current-loop interface.
Using the example of level measurement, various measuring principles are presented in RT 306. To this end, a glass tank contains two different 4…20 mA sensors that record the level. One of the sensors, a capacitive level sensor, measures the level directly. A piezo-resistive pressure sensor is used to measure the level indirectly.
All of the current-loop connections required for the cabling are led out with lab jacks on the front of the switch cabinet and are labelled. In addition to the analogue 4…20 mA interface, the sensors have a HART interface.
The measurement data is displayed directly on the integrated 2-channel line recorder. The measurement data can be exported via a USB interface and analysed on a PC (not included in the scope of delivery).
