KLD804 80G FM Radar Level Sensor

Introduction

KLD804 76-81GHz frequency modulation wave FMCW radar product (also called millimeter wave radar), it uses a millimeter wave band with high frequency, it can detect smaller targets and achieve more precise positioning than microwave radar with higher resolution and stronger confidentiality. Therefore, it has important applications in long-distance target detection, strong smoke and dust environment, long-distance imaging, multi-spectral imaging, etc.

Feature

(1)Based on self-developed millimeter-wave radio frequency chip to achieve a more compact radio frequency architecture;
(2) Higher signal-to-noise ratio, almost unaffected by level fluctuations;
(3) The measurement accuracy is millimeter-level accuracy (1mm), which can be used for metrology-level measurement;
(4) The measurement blind area is small (3cm), and the effect of measuring the liquid level of small storage tanks is better;
(5) The beam angle can reach 3°, and the energy is more focused, effectively avoiding false echo interference;
(6) High frequency signal, can effectively measure the level of medium with low dielectric constant (ε≥1.5);
(7) Strong anti-interference, almost unaffected by dust, steam, temperature and pressure changes;
(8) The antenna adopts PTFE lens, which is effective anti-corrosion and anti-hanging material;
(9) Support remote debugging and remote upgrade, reduce waiting time and improve work efficiency;
(10) It supports mobile phone Bluetooth debugging, which is convenient for maintenance work of on-site personnel.

Installation Method

Flange Installation

When using flange installation, the minimum distance between the instrument and the tank wall should be 200mm.

• datum plane
• vessel center or axis of symmetry

Hoisting Installation

Note: Please avoid vibration, strong electromagnetic interference and loads during installation.

Misalignment method:
1. On-line calibration: on-site process equipment needs to stop production;
2. Reference point calibration: full scale setting;
3. Upper computer calibration: 250Ω resistor, Hart converter, USB interface are required.
