Precision rotary potentiometer

Precision Rotating Potentiometer - Measuring Instrument with Resistance, Current or Voltage Output. Nowadays, the angular displacement sensor of EMF has reached a higher position than other similar measuring instruments in high-quality measuring tasks, because the angular displacement sensor of EMF can save more cost. Potential angular displacement sensor is mainly used for starting and braking control elements of railway system and shipping, rudder and propulsion system of ship, control driver of energy and chemical industry system, hoisting gear and fast orientation device of crane and excavator, tracking wind vane in meteorological measurement, as balanced potentiometer in textile and paper industry, as machinery and medicine. A measuring device for therapeutic instruments. 

The potential sensor has a high-resolution conductive plastic element or a high-resolution metal or copper-nickel alloy wire with different resistance and angle values. Potential sensors can be used as single-turn or multi-turn coil potentiometers for different models or multiple designs. The adjustment of measurement range for all series of sensors can be accomplished by short circuit trajectory, knob and functional coil. Some types of sensors are used with signal converters to provide 2,3,4 linear current or voltage output. In order to ensure its reliability in harsh environment, oil-filled sensors are suitable. Moreover, in order to protect all series of sensors from mechanical damage, dust and damp industrial exhaust, a series of protective enclosures with IP 40 to IP 68 are suitable, which are mounted on transmission devices and restriction switches. Instructions and Circuit Adjustment Method The coil on the plated armature ring is the resistance element of the ring winding that can provide any circuit, angle and resistance value.

1. Restriction of brushes by baffles

2. The brush with reactance coil rotates 360 degrees

3. Brush rotation without reactance coil 360 degrees

4. Arbitrary Arrangement of Short Circuit Trajectories

5. Arrangement of knobs

6. Specific coils with linear or sinusoidal or cosine characteristic curves

7. There are two electrical isolation coils on one coil. The copper wire coil with an angle less than 175_coated die-wound is a resistance element of linear coil for multi-turn coil potentiometer or linear single-turn coil potentiometer with a maximum angle of 335.
