What is an FMCW radar level gauge and how does it work?
An FMCW radar level gauge continuously emits frequency-modulated microwave signals and measures the frequency difference between transmitted and received signals. This allows extremely precise distance measurement with high resolution and stability.
What are the advantages of 80GHz radar level gauges?
80GHz radar level gauges offer:
- Ultra-high accuracy (±1 mm)
- Narrow beam angle for precise targeting
- Strong anti-interference capability
- Better performance in small or complex tanks
- Reliable measurement for low dielectric materials
They are ideal for high-end industrial measurement applications.
Can radar level gauges work in high temperature environments?
Yes, advanced radar level gauges can operate in extreme temperatures, with customized models supporting up to 1000°C, making them suitable for furnaces, reactors, and high-temperature processes.
What is the difference between FMCW radar and pulse radar?
- FMCW radar → higher accuracy and continuous measurement
- Pulse radar → simpler but lower resolution
FMCW radar is preferred for high precision and demanding applications.
Are radar level gauges suitable for corrosive or volatile media?
Yes, with appropriate antenna materials (such as PTFE or quartz isolation), radar level gauges can reliably measure corrosive, volatile, or crystallizing media without direct contact.
How do I choose the right radar level gauge?
Key factors include:
- measuring range and tank size
- medium properties (dielectric constant, corrosion)
- temperature and pressure conditions
- required accuracy
- communication and integration needs
Selecting the correct model ensures optimal performance and long-term reliability.
