4B Braime
4B Braime Rotech Shaft Encoder – Polypropylene
The 4B light duty polypropylene Rotech rotary shaft encoder is used primarily for protecting equipment and personnel from dangerous underspeed/belt slip conditions in extreme environments. Other applications include accurate speed control, direction of rotation detection, gate position indication and counting the number of revolutions of the shaft.
An inductive sensing device in the body of the encoder detects a steel rotor. On slow speed or accurate position control, a photo diode detects the slots on a steel disk. One pulse is created for each rotor or slot so the unit can be connected directly to a PLC/computer or 4B control module.
The shaft to be monitored is drilled and taped to take the 1/2 in. UNC Rotech Bolt. The unit is secured to the shaft with this bolt and is able to move with the shaft. No guards are required as the rotating components are encased inside the housing of the encoder. No brackets are required as the encoder couples directly to the end of the shaft and floats with the shaft.
4B Braime Roto-Safe™
The Roto-Safe rotary paddle switch is designed to detect high and low levels of bulk granular solids in bins, tanks, silos, and as blockage detectors in spouts where failsafe detection is required, or for dust hazard areas.
The detection of material is achieved by a rotating paddle. If material impedes the rotation of the paddle, the motor topples of its axis and triggers a contact. The power supply to the motor is cut and the contact signals that a critical level has been reached, which will cause the motor for any inlet or outlet to close down or start up. When the level of the material reaches normal levels again, the motor returns to its initial position and restarts. In the case of a power failure, the Roto-Safe has a fail safe relay that will signal the control room or sound an audible alarm indicating that the unit is not working. Through the control circuit, this alarm can stop any motor filling or emptying the silo. The Roto-Safe also has a built in rotation detection circuit. The output operates from 0 to 20 seconds after the motor has stalled. This feature can be tested by using the magnetic test feature on the outside of the case.
4B Braime S100-90 HDP-MD Starco™ Buckets – Plastic
A better concept in bucket design, Starco™ elevator buckets are engineered for higher capacity. Tapered sides ensure maximum bucket fill at a closer spacing. A unique front profile guarantees clean discharge over a wider range of operating speeds than conventional or other low profile elevator buckets.
