76-81GHz Radar level transmitter

SUPMEA WSR550 76-81GHz Radar level transmitter

The WSR550 is a non‑contact radar level transmitter in the high frequency band 76–81 GHz (FMCW mode). It supports both two‑wire and four‑wire configurations and is built for measuring liquid levels and also solid levels, especially in harsh environments.

Because of its high frequency, the WSR550 can better penetrate through dust, vapor, foam, or mist, helping maintain accurate readings even when other sensors may struggle.

The 76-81GHz series products refer to frequency modulated continuous wave (FMCW) radar products operating at 76-81GHz, supporting four-wire and two-wire applications. The product has multiple models, the range can reach 120m, and the blind zone can reach 8 cm. Because of its higher operating frequency and shorter wavelength, it is especially suitable for solid applications. The working method of transmitting and receiving electromagnetic waves through the lens has unique advantages in high dust and harsh temperature environments (+150). The instrument provides flange or thread connection, which makes installation convenient and easy.
