Product Description
Product Description
Based on frequency modulated continuous wave (FMCW) technology, the 80G radar level gauge measures the height or distance of materials by transmitting and receiving microwave signals. Its working principle is to emit a microwave signal with a frequency that varies linearly with time. When the signal encounters the surface of the measured material, it will reflect back and form a frequency difference with the emitted signal. By measuring this frequency difference and time delay, combined with the propagation speed of radar waves, the height or distance of the material can be accurately calculated.
The 80G radar level gauge achieves closed-loop control from signal transmission to liquid level output through a triple technical architecture of high-frequency signals, AI algorithms, and intelligent diagnosis, making it particularly suitable for high-precision measurement under harsh working conditions. Its schematic design takes into account both physical optical characteristics and digital signal processing technology, making it an ideal choice for Industry 4.0 intelligent tank area management.

A pressure transmitter converts the pressure of liquid, gas or steam into a standard electrical signal for PLC, DCS, recorder or control instrument input. It is widely used for pipeline pressure, tank level, flow measurement and process safety monitoring.
Confirm the pressure range, pressure type, medium, temperature, output signal, accuracy, installation thread, electrical connection and environmental requirements. For corrosive media, high temperature or sanitary applications, diaphragm material and sealing structure are especially important.
Gauge pressure transmitters measure pressure relative to atmospheric pressure. Absolute pressure transmitters measure pressure relative to vacuum. Differential pressure transmitters measure the pressure difference between two points and are commonly used for flow, filter and level measurement.
Yes. Xinyi Instrument can support customized pressure ranges, process connections, output signals, cable length, display options and model selection for different industrial applications.
