HCDAR-82 High Temperature Molten Solid Radar Level Gauge

High temperature molten solid radar level gauge

The HCDAR-8x series is a level measuring instrument that uses special millimeter wave (FMCW) technology. The working frequency is 76-81GHz, and the output signals include two-wire (4-20) mA, four wire (4-20) mA, and RS485. The maximum range is 120m, and the minimum blind spot is 8cm. The minimum antenna beam angle is about 3 °, which can achieve accurate measurement of liquid, solid, and dust materials.

Application: Liquid and Solid Measurement

Measurement range: 0-60m

Antenna type: lens/PTFE

Process connection: flange

Beam angle: 3 °

Response time: as small as 0.6S (depending on parameter settings)

Medium temperature: (-40~1200) ℃

Process pressure: (-0.1~2) MPa (with quartz isolation flange)

Accuracy:<2mm

Product Principle

The HCDAR-8x series emits a microwave signal with a frequency that varies linearly with time. The reflected signal from the microwave encountering the material is mixed with the emitted signal through a 'mixer'. The difference frequency between the two is proportional to the distance from the radar to the reflection surface, and the required distance information is obtained through FFT transformation.

Selection and Application

Product Features

Based on complementary metal oxide semiconductor (CMOS) devices, highly integrated, with higher signal-to-noise ratio and smaller blind spots.

2. 5GHz working bandwidth enables the product to have higher measurement resolution and accuracy.

3. The narrowest 3-antenna beam angle reduces the impact of interference in the installation environment on the instrument, making installation more convenient.

4. The wavelength is shorter and has better reflection characteristics on solid surfaces, so there is no need to specifically use universal flanges for aiming.

5. Support remote debugging and upgrading, reduce waiting time, and improve work efficiency.
