The instrument emits a continuous radar signal through its lens antenna. The frequency of this signal will change like a sawtooth. The transmitted signal is reflected by the medium and received by the antenna as an echo signal. There is always a frequency difference between the received signal frequency and the current transmission frequency. The frequency difference is directly proportional to the material level in the container, and the accurate value of the level is calculated through a specific algorithm of the sensor. The G80 series operates with very low transmission power in the W-band range.
Features
· Reliability: "ELL signal analysis technology" can reduce the impact of various false echoes to ensure high reliability of products
· Safety: It is designed and produced based on IEC61508 standard to ensure high safety of products
· Double cavity enclosure: It fully realizes the isolation of circuit cavity to ensure the safety of using electricity on-site
· Lightning protection: DHE G80 is equipped with built-in lightning surge protection to protect the instrument from lightning interference
· High precision: It adopts FMCW frequency modulation technology, and the product accuracy can reach ± 1mm.
· Small beam angle: It adopts the beam angle of 3°technology, which greatly improves the anti-interference ability.
· Small blind zone: It adopts small blind zone technology which can reduce the blind zone to a minimum of 2cm.
· Millimeter wavelength: It adopts millimeter wavelength technology, which has the ability to penetrate smoke, dust and fog, and is suitable for complex working conditions.
Advantages
· Remote Debugging: G80 can be remotely debugged through the remote communication module.
· Super Large Range: The maximum measuring range of G80 is 120m.
· High Temperature Resistance: G80 can measure the medium of which the temperature is less than or equal to 200 ºC
· Multiple output modes: 4~20mA,HART,Modbus.
· Super small antenna: G80 can be installed on the screw thread of which the size is greater than or equal to G1.
· Large bandwidth: It adopts 5GHz bandwidth technology to ensure product resolution and high signal-to-noise ratio.
