What is a radar level sensor and how does it work?
A radar level sensor measures level by emitting microwave signals toward the material surface and calculating the time it takes for the signal to reflect back. This allows continuous, accurate, and non-contact level measurement.
Can radar level sensors measure powder and bulk solids?
Yes, radar level sensors are widely used for powder and bulk solids such as cement, grain, and chemicals. Advanced signal processing and high sensitivity allow accurate measurement even in dusty environments.
What is the difference between 26GHz and 80GHz radar level sensors?
- 26GHz radar sensors → better for large tanks and general industrial use
- 80GHz radar sensors → higher accuracy and better for small tanks
26GHz sensors are ideal for long-range and cost-effective applications.
Are radar level sensors affected by dust or temperature?
Radar sensors are minimally affected by dust, temperature, or pressure, making them highly reliable in harsh industrial environments where other technologies may fail.
What industries use radar level sensors?
They are widely used in:
- cement and bulk material industries
- chemical and petrochemical plants
- oil & gas storage
- food and pharmaceutical production
They are ideal for challenging industrial environments.
How do I choose the right radar level sensor?
Key factors include:
- measuring range
- material type (liquid or solid)
- environmental conditions (dust, temperature, pressure)
- explosion-proof requirements
- output and communication needs
Selecting the right model ensures accurate and reliable measurement.
