EVA-NF4R15D14

The EVA-NF4R15D14 is a slide potentiometers, which is typically used as a voltage divider for noise or signal measurement. It is a self-contained unit that provides a linear measurement of amplitude from two separate input devices, the potentiometer wiper and one or more resistors. The EVA-NF4R15D14 consists of two resistive elements mounted side by side in a single package. The first element is a wiper that receives the applied input voltage due to the action of a sliding contact. The second element is a resistive material that can be adjusted for different sensitivities. While the wiper is being moved, the potentiometer (resistor) provides a corresponding resistance adjustment in response to the voltage change.The EVA-NF4R15D14 can be configured for both unipolar and bipolar operation. In unipolar mode, the input voltage is applied across the slider and resistors, causing the slider to move in unison with the applied voltage. The resistive element adjusts the sensitivity of the current measurement. In bipolar mode, two input voltages are applied to the slider and the resistors. As the slider is moved, one voltage is decreased while the other is increased, causing the resistive element to adjust the current measurement accordingly. The EVA-NF4R15D14 is typically used in applications where precise voltage and current measurements are required. They are commonly used to measure signal strength, amplitude, and noise in audio and video equipment. The device is also used to perform linear voltage divider measurements in high-frequency switching power supplies. It can also be used to measure the input voltage of an electric motor or generator.The EVA-NF4R15D14 is constructed from a variety of materials such as gold, nickel, silver, and stainless steel, which provide excellent corrosion resistance and stability under extreme temperatures. The wiper contact is made of a hard graphite material that is resistant to abrasion.In summary, the EVA-NF4R15D14 is a slide potentiometer device designed for precise voltage and current measurements. It is commonly used to measure signal strength, amplitude, and noise in audio and video equipment as well as in high-frequency switching power supplies to measure the input voltage of an electric motor or generator. Due to its excellent corrosion resistance and stability under extreme temperatures, the device is well suited for implementation in a variety of demanding applications.
