Overview: The Mini-Rotary is a compact and dependable level control device designed for use in tight spaces such as small bins and hoppers. It is suitable for a variety of dry solids and powders, including plastics, food, seed, and chemicals.
Specifications: The device operates on an input voltage of 110/230 VAC at 50/60 Hz, with a power consumption of 1.5 Watts. It features a single pole, double throw (SPDT) switch with a contact rating of 3A at 250 VAC. The rotary speed is 1 RPM, and it functions within a temperature range of -4°F to +140°F. The device is mounted through a 3/4” pipe fitting and includes a magnetic slip clutch to prevent motor gear damage. The enclosure is made of polycarbonate and is NEMA 1 rated, with a total weight of 0.77 lb.
Operation: The Mini-Rotary operates with a slow-speed synchronous motor that rotates a paddle to detect material levels. When material contacts the paddle, it stops, triggering an alert to notify the operator that the bin is full. Once the bin is emptied, the paddle resumes rotation, indicating the need for a refill. The device is designed to ignore changing material characteristics, ensuring reliable operation.
Features: Key features include a compact design ideal for small spaces, simple installation without the need for calibration, and a de-energizing motor to extend motor life. The motor torque sensitivity is adjustable, and the device can be equipped with optional four-vane or bayonet style sensing paddles.
Applications: The Mini-Rotary is particularly useful in process manufacturing environments where space is limited, providing an economical solution for level control in small bins and hoppers.
