Common Faults and Troubleshooting Methods

Output signal	Error	Possible cause of failure	Solution
4-20mA	Output <4mA	The sensor works in the upper dead zone	Adjust the installation position
	Output >20mA	The sensor works in the lower dead zone	Adjust the installation position
	Output 0mA	1. The magnetic ring falls off 2. Power supply failure 3. The wiring is not firm	Check ferrite, power supply and wiring
	Unstable output	1. The magnetic ring is not installed firmly 2. Insufficient power supply	Check ferrule and power supply
0-5V	Output<0V	The sensor works in the upper dead zone	Adjust the installation position
	Output>5V	The sensor works in the lower dead zone	Adjust the installation position
	Output 0V	1. The magnetic ring falls off 2. Power supply failure 3. The wiring is not firm	Check ferrite, power supply and wiring
	Unstable output	1. The magnetic ring is not installed firmly 2. Insufficient power supply	Check ferrule and power supply
0-10V	Output <1V	The sensor works in the upper dead zone	Adjust the installation position
	Output >10V	The sensor works in the lower dead zone	Adjust the installation position
	Output 0V	1. The magnetic ring falls off 2. Power supply failure 3. The wiring is not firm	Check ferrite, power supply and wiring
	Unstable output	1. The magnetic ring is not installed firmly 2. Insufficient power supply	Check ferrule and power supply

Application

Explosion-proof magnetostrictive displacement sensors have other application areas, such as in oil well platforms, oil tanks, oil storage and transportation monitoring, petroleum and chemical equipment, refining, oxygen transmission systems, hydrogen equipment, power plants, boilers, thermal power units, petrochemical, environmental protection, compressed air, light industry, machinery, metallurgy, and other measurement environments with explosion protection requirements.
