What is a magnetostrictive level gauge and how does it work?
A magnetostrictive level gauge measures liquid level using a magnetic float and a waveguide sensor. When a current pulse travels along the probe, it interacts with the magnetic field of the float, generating a return signal. The time difference is used to calculate the exact liquid level with extremely high precision.
What are the advantages of magnetostrictive level sensors?
Magnetostrictive level sensors offer:
- Extremely high accuracy (up to ±0.1 mm)
- Excellent repeatability and stability
- Continuous real-time measurement
- No mechanical wear except float
- Suitable for harsh and hazardous environments
They are widely considered one of the most accurate level measurement technologies available.
What is the difference between magnetostrictive and radar level transmitters?
- Magnetostrictive sensors provide ultra-high accuracy and are ideal for clean liquids in tanks
- Radar level transmitters are better for high temperature, vapor, or non-contact measurement
Magnetostrictive technology is preferred when precision and stability are critical, while radar is better for extreme process conditions.
Where are magnetostrictive level gauges commonly used?
They are commonly used in:
- Oil and fuel storage tanks
- Chemical processing industries
- Pharmaceutical production
- Food and beverage industries
- Industrial automation systems
Especially where high precision level monitoring is required.
Can magnetostrictive level sensors be used in hazardous areas?
Yes, many models are designed with explosion-proof certifications (Ex d IIC T6), making them suitable for oil & gas and chemical environments with flammable gases.
How accurate are magnetostrictive level transmitters compared to other sensors?
Magnetostrictive level transmitters are among the most accurate level sensors available, with accuracy up to ±0.1 mm, significantly outperforming technologies like ultrasonic or hydrostatic sensors in precision applications.
