Intelligent radar level transmitter cable type with two wire 4 to 20 mA
Quick Detail:
Description:
VT77 intelligent radar liquid level gauge is suitable for the measurement of working condition of blast furnace, thick roof tank and high install short pipe, the measuring range is 35 meters.
Microwave emited by guided wave radar transmit through detecting element( steel rod or steel cable) and encounter the measured medium,owing to the bielectric constant change suddenly,the microwave occur changed shape that result in reflection,parts of pulse energy are reflected.transmission pulse and echo pulse time interval are proportional to measured medium.
Micro wave pulses generated by the electronic units are emitted and received by the antenna system. The radar waves of the pulses travel at the velocity of light. The fling time is converted into level signal via the electronic units. A special time extending method can make sure the stable and accurate measurement within extremely short time.
Even under the more complicated working conditions with false echoes, the real level echoes can be recognized and identified by the latest microprocessing technology and debugging software

Competitive Advantage:
1 . Small antenna size, easy to install; Non-contact radar, no
wear, no pollution.
2. Almost 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.
