FineTek SE3 Mini Rotary Paddle Level Switch

FineTek SE3800 Compact Rotary Paddle Level Switch is to detect the presence of powdery or free flowing solids in small tanks, bins and hoppers. During normal operation (no material present) a synchronous motor rotates the paddle at one RPM. When this paddle rotation is impeded by material, surrounding the paddle, motor will stall and cause the micro-switch to change state (indicating an alarm or control).
