Level

Overview

76-81GHz frequency modulated continuous wave (FMCW) radar level meter (also known as millimeter wave radars) use a millimeter wave band with a higher frequency than Ku-band radars. They have important applications in long-range target detection, long-range imaging in strong smoke and dust environments, and multi-spectral imaging. They can detect smaller targets than microwave radars and achieve more accurate positioning, with higher resolution and stronger confidentiality.

As a 78GHz band radar used in the field of industrial measurement, it has high-precision, non-contact level and liquid level measurement, and has incomparable advantages over other ordinary microwave pulse radars and guided wave radars. It has extremely narrow beams and penetration capabilities, and can better adapt to ultra-complex working conditions without reducing measurement performance.

Features

•  It adopts ultra-large frequency modulation scanning frequency width and has a wide range of applications.
• High accuracy, large range, small blind area, and small beam angle
• Support standard HART, RS485/MODBUS bus protocols
• Support host computer setting software, tank side meter and other operation methods
• Support remote debugging function, Bluetooth or 4G module network can be used.
• 24VDC power supply, supports four-wire and two-wire systems
• The installation structure is simple and adaptable to various installation forms on site.
