Description

The STL700 bench allows the study of level regulation. A pump supplies water to a transparent test tank. A pressure sensor measures the water level in the transparent tank. A digital PID controller receives the level information and must adjust the speed of the pump controlled by the drive to reach the set point.

The unit is delivered complete, instrumented with technical and educational documentation in English as well as all the accessories necessary for proper operation (including the supervision software).

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

Its anodized aluminum structure gives it great robustness as well as a great flexibility of integration into your premises. The manufacture of this equipment meets the European machine directive
