1. Product overview
Introduction
The L719 series sensor is a 26G high frequency radar level measuring instrument with an output of 4... 20mA mold
Pseudo-signal, measuring large distances up to 70 meters. The antenna is further optimized with a new type of fast micro
The processor can perform higher rate signal analysis processing, so that the meter can be used for example: reactor or solid
Very complex measuring conditions for silos.
Principles
The high frequency microwave pulse emits a narrow microwave pulse, which is transmitted down through the antenna, and the microwave contacts the surface of the measured medium
It is then reflected back, picked up again by the antenna system and transmitted to the electronic circuit part which automatically converts it into level information
number Because microwaves travel so fast, the electromagnetic wave reaches the target and is reflected back to the receiver
The time is almost instantaneous)
Note: When using radar level timing, be sure that the high material level cannot enter the measurement blind area (the area shown in in the figure).
Features
The radar level meter uses an emission frequency of up to 26GHz and thus has:

Non-contact radar, no wear,

Antenna size is small, easy to install

Shorter wavelength, better reflection on tilted solid surfaces

The measurement blind area is smaller, and the measurement of small tanks will also achieve good results

The beam Angle is small, the energy is concentrated, the echo ability is enhanced, and the interference is avoided at the same time

Almost impervious to corrosion and foam

Almost unaffected by changes in water vapor, temperature, and pressure in the atmosphere

Severe dust environment will not affect electromagnetic wave operation

High signal-to-noise ratio for better performance even in fluctuating conditions
Range of blind areas
Range setting
High adjustment
Low level adjustment
The datum of measurement
Yes: bottom of thread
Or flange seal
Face - 2 -

High frequency, it is a good choice for measuring solid and low dielectric constant media
