80Ghz Radar Level Transmitter Application: Liquid Level Measurement: Waste Water Level Mild Corrosive Liquid Reservoir Level Flood Level Packing List: 1x Radar Liquid Level Sensor with 1m wire. Description: Technical Parameters: Radar Level: Two wire systemMax Rage: 10M, 20M, 30M, 50MAccuracy：±2mmSignal output: 4～20mAPower supply: DC 24V ( 22V~30V )Protection: IP67Display: Mobile Phone APP Sizes: ϕ76mm×107mm 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. Features: Simple installation and maintenance, convenient debugging (mobile phone APP debugging), long life.Ultra-low power consumption.It can output RS485 signals and provide 4-20mA signals.Working around the clock, continuous online collection.Wireless transmission, no need to dig cable trenches, no impact on channel lining, tree planting and other engineering construction.The beam angle is small, the energy is concentrated, and it has stronger anti-interference ability, which greatly improves the accuracy and reliability of the measurement. Tips: We are an OEM manufacture, we can customize products according to your requirements.
