Analysis of common failures of liquid level gauges with magnetic flap

Magnetic flap level gauges often experience failures in the actual application process and the reasons for these failures are varied, some are caused by the failure of a single component, others are caused by the failure of multiple components at the same time.

Next, the most common faults and causes of the magnetic flap level gauge in the application process are analyzed as follows: NXsTextile Testing Instruments, Testing Equipment Manufacturer


Fault 1. On-site display analysis of abnormal causes of a normal long-distance transmission:NXsTextile Testing Instruments, Testing Equipment Manufacturer


In general, there are many reasons for this error, and the following are the most common reasons:NXsTextile Testing Instruments, Testing Equipment Manufacturer


1. Resistance welding. 2. The pressure exceeds the rating, resulting in damage to the switch. NXsTextile Testing Instruments, Testing Equipment Manufacturer


3. The glass tube reed switch for home use is fragile, and the reed switch is short-circuited or open, causing the long-distance transmission abnormality. NXsTextile Testing Instruments, Testing Equipment Manufacturer


4. When the temperature of the medium is too high, the metal sheet will heat up and expand, and the metal contact gap of the dry reed switch is small, so it is easy to occur in the closed state. NXsTextile Testing Instruments, Testing Equipment Manufacturer


Error 2. The remote transmission and magnetic flap do not move. This error phenomenon is usually caused by the anomaly of the float. The main phenomena are as follows:NXsTextile Testing Instruments, Testing Equipment Manufacturer


Because the float is damaged, resulting in incorrect reading on the display panel and damage of the float in the liquid level gauge with magnetic flap. Usually the reasons are as follows:

1. Due to the wrong design of the strength of the float, it will cause it to sag inward and be deflated under pressure. NXsTextile Testing Instruments, Testing Equipment Manufacturer


2. The weld is not penetrated or leaking, so the weld will rupture when the float is pressurized and the float enters the water. NXsTextile Testing Instruments, Testing Equipment Manufacturer


3. The float cannot be used normally due to long-term use or demagnetization after long-term use at high temperatures. NXsTextile Testing Instruments, Testing Equipment Manufacturer


4. Since the magnet steel in the float is loose, the float cannot work normally. NXsTextile Testing Instruments, Testing Equipment Manufacturer


Error 3. Because the float is stuck, the reading on the display panel is inaccurate and the float in the magnetic level gauge is stuck. The most common reasons are as follows:
NXsTextile Testing Instruments, Testing Equipment Manufacturer


1. The ambient temperature is too low and the float cannot move normally due to the freezing of the medium. NXsTextile Testing Instruments, Testing Equipment Manufacturer


2. The installation angle of the buoy is less than 87 degrees. Since the buoy is tilted, the up and down movement of the buoy will be affected. NXsTextile Testing Instruments, Testing Equipment Manufacturer


3. The float magnetically absorbs iron filings or other debris, causing the float to get stuck and unable to move normally. NXsTextile Testing Instruments, Testing Equipment Manufacturer


4. Float stays dry due to poor sealingch the infiltrated impurities hang, so that the swimmer can neither rise nor fall. NXsTextile Testing Instruments, Testing Equipment Manufacturer


So-called finding the cause of the error is half the solution. Through the above analysis of the most common faults of the magnetic flap level gauge, we have basically found a way to deal with the problem and can take targeted action according to the faults and their causes.
