Trimmer potentiometers are widely used in various industries for precise control of electronic systems. The 3319W-1-201 trimmer potentiometer is a high precision unit designed for applications requiring a low operational temperature and high control accuracy. This article will explain the application field and working principle of the 3319W-1-201 trimmer potentiometer.

The 3319W-1-201 is designed for high accuracy control of voltage variable components in precision control applications. It provides a precision voltage adjustment range from 0.001 to 90 volts while maintaining low temperature operation. As such, the trimmer pot can be used in multiple applications requiring high accuracy, including communications, factory automation, medical, test and laboratory equipment.

The core of the 3319W-1-201 is a precision wiper mechanism which allows accurately calibrated control of the voltage range. This enables precise adjustment of electronic components to provide accurate control of the voltage across the device. The accuracy achieved is certified as 0.1% minimum at full scale, allowing for the most precise control achievable with a trimmer potentiometer.

In operation, the core of the 3319W-1-201 trimmer pot is mounted between two conductors. Applied voltage across the conductors acts to draw electrons from the surfaces of the wiper, gradually changing the voltage output. As the wiper is rotated, it travels across an internal set of contacts which resistances themselves to the wiper’s movement. The varying levels of resistance experienced by the wiper as it moves across the contacts allows for precise voltage control.

The 3319W-1-201 also features an extended temperature range, allowing for a wider range of applications. This is accomplished through the use of a specially designed heating element and insulation. Instead of relying on external components, the trimmer is mounted directly onto the element, preventing thermal drift and resulting in highly precise adjustments. The extended temperature range also makes it suitable for use in extreme environments such as high altitudes or in soils or liquids.

The 3319W-1-201 trimmer potentiometer is widely used in the medical, test and laboratory equipment, communications, and factory automation industry. It is designed for easy installation and is resistant to shock and vibration. Furthermore, its low thermal drift and high accuracy make it the perfect choice for applications requiring precise voltage control.
