JWrada-32 Explosion-Proof Radar Level Meter
The JWrada-32 Radar Level Meter Explosion-Proof Radar Level Transmitter adopts advanced 80GHz FMCW technology with a measuring range of up to 120 meters.
The JWrada-32 Explosion-Proof Radar Level Meter features advanced 80GHz FMCW radar technology for precise, non-contact level measurement up to 120 meters. With dual certifications for gas and dust explosion protection（ Ex db IIC T6 Gb; Ex ia IIC T6 Ga; Ex tb IIIC T80℃ Db）, it is ideal for hazardous areas.
It supports HART protocol, Bluetooth configuration, and the “Jiwei Smart Control” WeChat mini program for easy wireless setup and monitoring.
Designed for high-temperature (up to 220°C) and dusty environments, it ensures reliable performance with a high SNR design and adaptive echo algorithm, maintaining accuracy even in steam, agitation, or low-dielectric media.
The JWrada-32 explosion-proof radar level meter utilizes Frequency Modulated Continuous Wave (FMCW) technology, with a working frequency of 80GHz. The radar waves generated by its internal circuitry are transmitted through an antenna, reflected by the surface of the measured medium, and then received by the same antenna. The frequency difference between the transmitted and received signals is proportional to the level distance. The collected signals are processed using Fast Fourier Transform (FFT) to obtain the frequency spectrum of the reflected echo, allowing for precise calculation of the level or medium distance. The JWrada-32 is suitable for hazardous environments, ensuring stable and accurate measurement.
