KLD803 PTFE Material Radar Distance Level Sensor With RS485 4 - 20mA Output
KLD803 80G FM Radar Level Sensor
Introduction
KLD800 series 80G radar level gauge adopts frequency modulated continuous wave (FMCW) technology. The antenna emits a high-frequency FM radar signal, and the frequency of the radar signal increases linearly. The transmitted radar signal is received by the same antenna after being reflected by the measured medium. At the same time, the frequency difference between the transmitted signal frequency and the received signal frequency is proportional to the measured distance. The collected frequency difference signal is subjected to fast Fourier transform (FFT) to obtain the spectrum of the reflected echo, and the distance to the target to be measured is calculated based on this.
Feature
△ The radar adopts spherical lens, which is not easy to hang in large area, and has obvious advantages in measuring the working conditions of condensation environment combined with proprietary algorithms;
△ The radar has a highly stable algorithm, which can stably track the liquid level measurement such as liquid level splash, splash and eddy current caused by mixing and spoiler;
Advantages of PTFE
- PTFE offers many unique advantages. These include:
- Wide operating temperatures (-400° F to 500° F)
- Resistance to Corrosion (great replacement for rubbers which are affected by corrosion)
- Excellent Electrical Properties
- Unlimited Shelf Life
- High resistance to water, moisture & UV
- Low coefficient of friction
- High Flexural Strength
- Strong non-stick properties
- Good fatigue resistance under low stress
- Availability of food, medical and high-purity grades
- Low water absorption/hydrophobic

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
Xi'an Kacise Optronics Tech Co., Ltd considers itself a solution provider and manufacturer. We offer maximum flexibility and a cost-optimised offer for our OEM customers.
Advantages of using a 4 to 20 mA Signal
- It can be run over long distances with minimal signal losses compared to voltage type signals
- A varying current loop load impedance or supply voltage will not significantly affect the signal as long as it does not exceed recommended component limits
- Rugged signal with low electromagnetic susceptibility
- Saves on cable wire because it only needs 2 wires to function
- Live zero reading verifies sensor is electrically functional
The major advantages of RS-485 interface are:
- Two-way data exchange via one twisted pair of wires;
- support for several transceivers connected to the same line, i.e., the ability to create a network;
- long length of the communication line;
- high transmission speed.
