Level Sensor/Switch Handles Diverse Apps

The NIR-9 level switch is suitable for a wide variety of applications for bulk material and solids in silos and hoppers. Product level is reliably controlled, regardless of humidity and conductivity of the product. Different vanes and process connections are available, according to product and tank size. During operation, a motor drives a rotating vane on an extended shaft. As soon as the media reaches the rotating vane, its rotation is impeded. The restoring force moves the pivoted motor away from its original position. A micro-switch is actuated, which gives out an alarm signal. A second microswitch turns off the motor. If the filling level decreases, the rotating vane is released again and the force of a spring pulls the motor back to its original position. The motor restarts and the working contact is switched back. The switching sensitivity can be adjusted to three different settings by changing the spring position.
