Fine tek Rotary Paddle switch
15.Rotary Paddle Level Switch-SE Series
SE series operating principle is simple. A unit is usually located through a bin wall at the top, middle or low level of a bin. During normal operation (no material present) a synchronous motor rotates the paddle at 1 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)
Airtight sealing device, outdoor application is available.
Unique sealing ring design, it can perform good dust protection to avoid the dust permeate into housing body along with the shaft.
The torque force is adjustable.
The performance of torsion is stable and reliable.
If the rotary paddle bears an extra overload, the motor will be appeared slide to prevent the inside mechanism damaged.
It is rationally designed, the inside mechanisms are easily tore down for checking, maintenance and replacement. It doesn”t necessary to remove the complete set from the tank.
Very suitable for small tank and material of low density
16. Capacitance Level Switch-SA Series
capacitance level sensor measuring principle is base on the ” capacitance effects ” , when this level sensor is set on a silo, it will be formed a condenser between the detector electrode and the silo wall. The capacitance of this condenser varies proportional to the change of material specific inductivity ( DK value) of the material stored in the silo , when the more material substances increased in the silo, the more capacitance value added simultaneously, then it will let his interior circuit “s resonant signal to create a bigger amplitude ,and such a signal amplitude become more or less than factory default threshold value, the relay device will be energized.
