High frequency digital 4-20mA radar level meter
Product Overview:
This series of radar level meter adopted 26G high frequency radar sensor, the maximum
measurement range can reach up to 70 meters. Antenna is optimized further processing,
the new fast microprocessors have higher speed and efficiency can be done signal
analysis, the instrumentation can be used for reactor, solid silo and very complex
measurement environment.
Paraments:
Application: various corrosion liquid
Antenna material: PTFE
Measurement range: 10 m
Process connection: thread, Flange
Medium temperature: -40C --130℃
Process pressure:-0.1~0.3MPa
Accuracy: ±5mm
Power supply: 24VDC (two lines, four lines)
Protection grade: IP67
Frequency range: 26GHz
Explosion-proof grade: Exia Ⅱ C T6 Ga/ Exd ia IIC T6 Gb
Signal output: 4. 20mA/HART (two / four) RS485/Mod bus
Working Principle:
Radar level transmitter antenna microwave pulse is narrow, the downward transmission antenna. Microwave exposure to the medium surface is reflected back again by the antenna system receives, sends the signal to the electronic circuit automatically converted into level signals (because the microwave propagation speed, electromagnetic wave to reach the target and the reflected back to the receiver this time is almost instantaneous).
Features:
1Small antenna size, easy to install; Non-contact radar, no wear, no pollution.
2Almost no corrosion, bubble effect; almost not affected by water vapor in the atmosphere, the temperature and pressure changes.
3 Serious dust environment on the high level meter work has little effect.
4 A shorter wavelength, the reflection of solid surface inclination is better.
5 Beam angle is small, the energy is concentrated, can enhance the ability of echo and to avoid interference.
6 The measuring range is smaller, for a measurement will yield good results.
7 High signal-to-noise ratio, the level fluctuation state can obtain better performance.
8 High frequency, measurement of solid and low dielectric constant of the best choice
