Description

The STL500 bench allows the study of the temperature control. Two temperature sensors a T-type thermocouple or a Pt 100 probe 3 wires measures the water temperature in the tank. A digital PID controller receives the temperature information and has to adjust the heating power of the resistor immersed in the tank to reach the setpoint. The bench also allows to wire the control loop with double sink sockets in Ø = 4 mm. The unit comes complete with instrumentation with technical and pedagogical documentation in French and all the accessories required for proper operation (including the monitoring software).

The robust design of this equipment makes it perfectly suited for use in schools.

Its anodized aluminum frame with legs gives it great strength as well as great flexibility of integration into your premises. The manufacturing of this equipment meets the European machine directive.
