Continuous Wave Radar Level Sensor 80Hz Explosion Proof Radar Level Transmitter

Continuous Wave Radar Level Gauge Without Direct Contact With The Medium

Continuous wave radar level gauge is a common liquid level measurement instrument. It uses radar technology to emit continuous microwave signals and calculates the liquid level by measuring the intensity of the signal's echo.

Product Advantages

Non-contact Measurement: The antenna does not come into contact with the medium, making it suitable for corrosive, high-temperature, high-pressure, viscous, and easily crystallizing complex media.
High Precision: The measurement accuracy is usually within ±1 to 3mm, far exceeding non-contact methods such as ultrasonic.
Almost Unaffected by Working Conditions:
- Unaffected by Pressure and Temperature Changes: The speed of electromagnetic wave propagation is hardly disturbed by these factors.
- Unaffected by Changes in Gas Phase Medium Composition and Density: A significant advantage over ultrasonic.
- Strong Resistance to Steam, Dust, and Foam: Especially high-frequency (such as 26GHz, 80GHz) radars, with small beam angles, concentrated energy, and stronger penetration.
No Moving Parts, High Reliability, and Low Maintenance.

Comparison with Pulse Radar Level Gauges

Characteristics	Continuous Wave Radar	Pulse Radar
Working Principle	Transmits waves with continuously varying frequencies and measures the frequency difference between the transmitted and received waves.	Transmits short pulses and measures the time difference between the transmitted and received waves.
Signal Processing	Processed in the frequency domain, requiring high signal quality and relatively complex circuits.	Processed in the time domain, with an intuitive principle and relatively simple circuits.
Accuracy	Extremely high. The accuracy of measuring the frequency difference can be very high, so it is usually more accurate than pulse radar.	High, but may be slightly inferior to FMCW in measuring extremely short distances or requiring extremely high accuracy.
Dead Zone	Minimal or almost non-existent. As it is a continuous wave, it can measure very short distances.	Has a certain dead zone (cannot measure near the antenna), as the receiver needs to be turned off during pulse transmission.
Cost	Usually higher (especially in high-frequency bands).	Usually lower, with good cost performance.
Application Focus	Applications with extremely high requirements for accuracy and reliability, such as trade settlement, fine chemicals, and small container measurements.	Strong versatility, suitable for most industrial liquid and material level measurements, and is one of the market mainstreams.

Continuous wave radar level gauges, with their blind spot-free feature, ultra-high precision and outstanding reliability, are the "high-end" solution in industrial liquid level measurement. Although their cost is usually higher than that of pulse radar, they are the irreplaceable choice in demanding measurement points, small containers or situations requiring extremely high measurement stability, such as safety interlocks and trade handovers.
