When the overcurrent of the internal circuit of the general thumbwheel potentiometer is too large, in order to consider its safe use, a resistor can be connected in parallel with it, which can play a shunting role. Avoid some troubleshooting problems. So do you have a better understanding of the use of thumbwheel potentiometers? Do you have a thorough understanding of the matters needing attention in the operation?

Next, I will tell you about the safety knowledge of the use of the thumbwheel potentiometer.

Description of Safety Knowledge for Use of thumbwheel potentiometer

1. Analysis of Noise Problem of thumbwheel potentiometer
Generally speaking, the dynamic noise of thumbwheel potentiometer is called the dynamic noise of thumbwheel potentiometer when the dynamic contact point of the potentiometer slides on the resistor under the action of external voltage. However, the number of dynamic contact points and the magnitude of applied voltage of potentiometer are all caused by the magnitude of dynamic noise value of potentiometer and rotating speed, contact resistance between contact point and resistor body, and uneven variation of resistivity.

2. Analysis of Rated Voltage of thumbwheel potentiometer
The actual working voltage of the thumbwheel 6mm potentiometer is less than the rated working voltage, and under the condition of the maximum working voltage of the thumbwheel potentiometer, long-term reliable work, so the maximum working voltage allowed to bear is also known as the rated working voltage. However, if the actual working voltage is higher than the rated working voltage, the power of the thumbwheel potentiometer will exceed the rated power, which will lead to overheating and damage.

3. Analysis of contact reed of thumbwheel potentiometer
The thumbwheel 6mm potentiometer is a component connecting brush and collector for contact reed. It mainly transmits the output of brush to collector and potentiometer. The contact spring and the collector is a kind of dynamic contact connection, and the corresponding contact spring should have good elasticity, in order to ensure that there is a certain elastic pressure on the collector, and its conductivity and thermal conductivity, hardness and wear resistance should be matched with the collector. Therefore, the general contact reed has a great influence on the mechanical durability and contact stability of potentiometers.

Performance and Function of thumbwheel potentiometer

1. When the overcurrent of the internal circuit of the general thumbwheel potentiometer is too large, in order to consider its safe use, a resistor can be connected in parallel with it, which can play a shunting role. Avoid some troubleshooting problems.

2. In the operation of some equipment with high performance requirements, the thumbwheel 6mm potentiometer can be connected by a coupling circuit, which means that a resistance can be connected in series in the coupling circuit. The main purpose is to prevent the possible high frequency oscillation of the circuit from affecting the use of the potentiometer.

3. For a thumbwheel potentiometer, the voltage at a certain point in the circuit is lower than that of the power supply when the potentiometer is connected between the power supply and a certain point in the circuit. Thus, the resistance between the two ends of the circuit is connected, that is, the resistance between the two isolation points of the potentiometer is not zero.
