NYRD701 PTFE 1.8GHz Guided Wave Radar Level Meter
The guided wave radar level meter is a level meter based on the principle of time domain reflection (TDR). The electromagnetic pulse of the radar level gauge propagates along the steel cable or probe at the speed of light. Part of the pulse of the level meter is reflected to form an echo and return to the pulse transmitter along the same path. The distance between the transmitter and the surface of the measured medium is proportional to the propagation time of the pulse during that period, and the liquid level height is calculated.

Guided wave radar level meter antenna using PTFE material, PTFE (PTFE or PTFE), commonly known as "plastics king", is made up of tetrafluoroethylene by the polymerization of polymer compounds, it has excellent chemical stability, high corrosion resistance, sealing, lubrication is not sticky, electric insulation and good anti-aging endurance, PTFE has the following features:
- High temperature resistance -- operating temperature up to 250℃.
- Low temperature resistance -- good mechanical toughness; Even when the temperature drops to -196℃, 5% elongation can be maintained.
- Corrosion resistance - inert to most chemicals and solvents, resistant to strong acids and bases, water and various organic solvents.
- Weather resistance - has the best aging life of plastics.
- High lubrication - the lowest friction coefficient of solid materials.
- Non-adhesion - is the minimum surface tension in a solid material and does not adhere to any substance.
- Non-toxic -- with physiological inertia, as artificial blood vessels and organs implanted in the body for a long time without adverse reactions.
Radar Level Meter Operating Principle
The high-frequency microwave pulse emitted by the guided wave radar propagates along the detection component (steel cable or steel rod), and when it encounters the measured medium, due to the sudden change of the dielectric constant, it causes reflection, and a part of the pulse energy is reflected back. The time interval between the transmitted pulse and the reflected pulse is proportional to the distance of the measured medium.
