SRP Rotary Paddle Level Sensor

The SRP Series rotary paddle point level sensor is a point level indicator used for high and low level alarm to detect the presence and absence of materials within bins, hoppers and silos containing powder and bulk solids. The level point sensor is mounted on the top or the side of a bin to prevent bin overflows and material outage. A robust synchronous motor drives the shaft and the chosen attached paddle rotates freely in the absence of material. As material comes in contact and impedes the paddle rotation, two limit switches internal to the assembly will be activated. The first limit switch disconnects power to the motor to prolong the life of the motor and save power; the second limit switch changes the state of the output relay contacts. As material falls away from the paddle, the state of the output relays changes and power is applied to the motor and rotation of the paddle resumes. In addition, the adjustable time delay provides a 0-12 second adjustment to eliminate nuisance alarms due to shifting and surging materials.
