Intelligent Radar Level Gauge SYC-LD702Product Overview
1.1 Introduction
The GDLD series sensor is a radar based level measuring instrument with a measuring distance of up to 20 meters, which can be used for storage tanks
Measure the level of intermediate buffer tanks, process containers, and various silos, and output 4-20mA analog signals.
1.2 Characteristics and advantages
● Adopting non-contact measurement with * and extremely stable material manufacturing
Measure the level of liquid and solid media
Can measure all media with a dielectric constant greater than 1.8
● Measurement range 0... 20m
Adopting a two-wire system and loop power supply technology, the power supply voltage and output signal are transmitted through a two core cable,
● 4... 20mA output/HART (two-wire)
Not affected by pressure, temperature changes, inert gases, vacuum, smoke, noise, steam, dust, and other working conditions
Not affected by changes in medium density, viscosity, and temperature
The process pressure can reach 40 bar, the process temperature can reach 220 ℃, the resolution is 1mm, there are no blind spots, and high precision.
Two wire technology is an excellent alternative product for differential pressure instruments, magnetostrictive instruments, radio frequency admittance instruments, and magnetic flap instruments.
Sensitive measurement, fast refresh rate, easy installation, sturdy and durable, maintenance free.
The measurement method adopts microwave pulses and can operate normally within the industrial frequency range. Low beam energy, can be installed in
All kinds of metal and non-metal containers or pipelines are harmless to human health and the environment.
1.3 Measurement principle
High frequency microwave pulses are transmitted and received through an antenna system, and radar waves travel at the speed of light. The travel time can be determined by the electronic component
The item is converted into a level signal. A special time extension method can ensure stable and accurate measurements.
Even in complex working conditions where false echoes exist,
1.4 Input
The antenna receives reflected microwave pulses and transmits them to the electronic circuit. The microprocessor processes this signal and identifies it
The echo generated by micro pulses on the surface of materials. The correct recognition of echo signals is completed by intelligent software, with an accuracy of up to millimeter level.
The distance D from the surface of the material is proportional to the time travel T of the pulse: D=C × T/2 (where C is the speed of light)
Since the distance E of the empty tank is known, the level L is: L=E-D
1.5 Output
By inputting the empty tank height E (=zero point), full tank height F (=full range), and some application parameters, the application parameters can be set
The number will automatically adapt the instrument to the measurement environment. Corresponding to 4... 20mA output.
