K33-FLK3B Industrial Controls

K33-FLK3B is a type of bar graph meter which is widely used for indicating the position of a Variac. This instrument is usually used to measure the output voltage of a dc power source or to compare two ac waveforms. It is usually installed in various industrial machines, such as motor controllers, generators, electric furnaces, and welding machines.

The K33-FLK3B bar graph meter consists of several components such as a graduated aluminum scale, a circular display, a zero adjuster, an adjustment potentiometer, a voltage selector switch and a connection port. The graduated aluminum scale, which is divided into five sections, consists of an extending bar which is labeled with the maximum and minimum values of the meter. The circular display is used to indicate the position of the Variac. The zero adjuster is used to calibrate the meter while the adjustment potentiometer is used to measure the output voltage. The voltage selector switch is used to select the appropriate voltage to be measured. The connection port is for connecting the meter to the Variac.

The basic working principle of the K33-FLK3B is quite simple. The Variac is connected to the bar graph meter and it is through this connection that the output voltage of the Variac is measured. The zero adjuster is used to calibrate the meter to the preset voltage. As the Variac is adjusted, the bar graph display will move up or down accordingly. The adjustment potentiometer is used to measure the difference between the maximum and minimum values. When the desired level is reached, the voltage selector switch is set to zero, which will cause the bar graph to indicate the correct level.

The K33-FLK3B bar graph meter is widely used in variacs used for machines/devices that require speed regulation or AC voltage requirement for optimizing performance. A few of these machines include electric furnaces, motors, generators, welding machines, or any other industrial devices which require a certain level of voltage. It is also especially useful for applications where a real-time display is desirable. The instruments are popular because of their economy, accuracy, robustness, and ease of installation.

In conclusion, the K33-FLK3B bar graph meter is a widely used instrument for indicating the position of a Variac. Its components such as the graduated aluminum scale, the circular display, the zero adjuster, the adjustment potentiometer, and the voltage selector switch, work together to accurately measure and display the output voltage. The instrument is used in variacs and is also suitable for a wide range of applications where a real-time display is desirable. It is preferred for its economy, accuracy, robustness, and easy installation.
