Project Description

80GHz Radar Level Transmitter (Hygienic Version)



  • 2-wire 80GHz FMCW Radar

  • Hygienic & Sanitary Application

  • Measuring range: liquid up to 20 m

  • Accuracy:  Liquid ±2 mm

  • Narrow emitting angle: 5°

  • PTFE sealed lens, not affected by deposits/condensate water

  • Hygienic fittings clamp 2” or customized.

Working principle

Frequency modulation continuous wave (FMCW) technology is adopted in the object level meter of 80GHz radar level transmitter. The continuous wave with frequency variation is transmitted within a certain period, and the echo reflected by the object has a certain frequency difference with the transmitted signal. The distance information between the target and the radar can be obtained by measuring the frequency difference.
Radar level meter, as a new industrial level measuring instrument, has the characteristics of high temperature resistance, high pressure resistance, vacuum resistance, strong penetration, temperature, steam, dust and other effects.


This Hygienic 80GHz Radar Level Transmitter have been specially developed for the needs of the pharmaceutical industry, The standardized fittings of the hygienic adapters can be selected as needed and only require minimal effort to install. This end-to-end concept allows simple integration and fast maintenance – it also reduces spare parts inventories and production downtime.
