RDS Sensors

Reed Switch and Magnets

Principle: Closing contact induced by a magnetic field.

Example applications: Rotation, distance, area, event counting


Principle: Sensor detects presence of conductive material.

Example applications: Rotation, distance, area, event counting

Rotary Encoder

Example applications: Seed drills, fertilizer/salt spreaders, harvesters. 360 pulses/rev gives good

response and resolution even at low speeds.


Principle: Capacitance change due to change of dielectric constant

Example applications: High/low level sensing of granular materials. Fertilizer/salt spreaders,

combine grain tanks, grain drills, silos.


Principle: Strain Gauge

Example applications: Load and overload measurement on vehicles. Easily installed onto vehicle chassis or stressed member.


Example applications: Crop sprayers, hydraulic pressure monitoring/measuring

Grain Flow

Principle: Dynamic measurement of occlusion time as loaded paddle passes light beam

Example applications: Grain flow measurement on paddle elevators. Used on combine harvesters for the measurement of both clean grain and returns grain.


Principle: Capacitive

Example applications: Continuous measurement of moisture on combine harvesters, grain driers, etc
