JWrada®-32 Radar Level Meter
JWrada-32 80GHz Radar Level Meter with Bluetooth 5.0, HART protocol, and intelligent echo-learning ensures precise, maintenance-free measurement of liquids and solids. Certified explosion-proof for gas and dust, it delivers reliable performance in harsh and hazardous environments.
JWrada®-32 Radar Level Meter is designed for conventional liquid and solid level measurement applications. Based on 80GHz millimeter-wave radar technology, it features a 38 mm lens antenna with a maximum measuring range of up to 60 meters. With excellent focusing performance and strong interference resistance, it meets both liquid level and bulk solid level measurement requirements.
Radar level meters transmit high-frequency (80GHz) frequency-modulated continuous wave (FMCW) signals with linearly increasing frequency through the antenna and receive the reflected signals from the material surface. The transmitted FMCW signal is mixed with the reflected echo signal to generate an intermediate-frequency (IF) signal. By analyzing the frequency spectrum obtained through Fast Fourier Transform (FFT) processing of the IF signal, the signal propagation time (TDR) can be indirectly calculated. Combined with the speed of light, the distance between the radar antenna and the material surface is accurately determined, enabling precise level measurement.
- High-precision measurement (±1 mm accuracy), 60 m measuring range, and no dead zone.
- Built-in Bluetooth 5.0 module, combined with the “JW Tools” mobile APP, enables wireless commissioning and monitoring for convenient field operation. Cloud data networking also supports remote commissioning and monitoring.
- Intelligent echo processing algorithms support false echo learning, multi-echo separation, and dynamic target tracking, maintaining high-quality and accurate measurement performance even under complex operating conditions.
- Strong interference resistance, capable of stable measurement in challenging environments with agitation, steam, dust, and electromagnetic interference.
- Maximum operating temperature up to 220°C, suitable for high-temperature applications.
- Certified by the National Explosion Protection Certification Center, with explosion-proof, intrinsically safe, dust explosion-proof, and dust intrinsically safe certifications (Ex db IIC T6 Gb; Ex ia IIC T6 Ga; Ex tb IIIC T80℃ Db; Ex ia IIIC T200 80℃ Da).
- Suitable for conventional liquid level measurement and level measurement of powders and solid particles with higher dielectric constants.
