Product introduction

UFKA-01-04 series manual self-checking float level controller  
 
UFKA series manual self-checking float level controller is suitable for liquid level control in various containers. When the liquid level reaches the up and down switching value, the controller contact outputs the switch signal.
 
 
◆Overview
 
UFKA series manual self-checking float level controller is suitable for liquid level control in various containers. When the liquid level reaches the up and down switching value, the controller contact outputs the switch signal.
 
The controller is externally equipped with a manual detection operating mechanism, as long as the operating panel is rotated, the internal mechanism can be linked to achieve the purpose of debugging the detection instrument, thus providing an ideal equipment for liquid level control.
 
Features

Structure principle
UFKA series floating ball liquid level controller is composed of separate wetted parts and contact parts. When the liquid level of the measured medium rises or falls, the float rises and falls, causing the magnetic head at the end of the lever to move in the opposite direction. , Swing downwards, if the liquid level rises (decreases) to the limit position, the magnetic head aligns with the internal moving contact and also swings up and down to disconnect from the static contact contact area, and an alarm signal is issued.
If you check whether the instrument is working properly, you can turn the detection handle 90° to the detection indication position, and the lock block will also rotate 90°C. The floating ball is fixed at the limit position by the pull pin on the magnetic steel, so that the float is like a When the liquid level reaches the action position, it is switched once to check whether the controller system is working normally.
