Abstract
An intelligent radar level instrument is composed of a signal processing converter, an oscillator, an isolator, an operation interface, a display, an alarm, a frequency mixer, a connecting part, antennae, a motor, a rotating rod, a telescopic shaft, a fixing seat, a protection cover, a flange and the like. Needed information can be displayed more obviously through the display arranged on an operation panel, and the operation panel and the alarm can give out an alarm when the instrument is failed; the operation panel, the signal processing converter, the frequency mixer, the connecting part and the isolator are sequentially connected, and a vibrator is arranged outside the isolator to be used for enhancing the stability of signals; through adjustment of the height of the antennae and rotatable and continuous measurement of the antennae at the two ends, the measuring precision is improved, the stability of the signals is enhanced, the safety guarantee of the antennae is improved, the connecting capacity is improved, and the alarm can be given through the alarm.
Description
Technical field
The present invention relates to radar levelmeter, particularly relate to a kind of intelligent high-precision radar levelmeter.
Background technology
Radar levelmeter adopts the measuring method of microwave pulse, and can be normal in industrial frequency wavelength band, and beam energy is low, can be installed in various metal, nonmetallic vessel or pipeline, carries out contactless continuous coverage to the thing position of liquid, slurry and particulate material; Be applicable to dust, temperature, pressure change greatly, have the occasion that inert gas and steam exist.
The extremely short microwave that radar levelmeter emissive power is very low is launched by antenna system and receives.Radar wave runs with the light velocity; Working time can be converted into thing position signal by electronic unit.A kind of special time extension method can guarantee stable in very short time and accurate measurement.Even if when there is false reflection, up-to-date microprocessing and software also can analyze effluent position echo exactly.By input pod size, overhead distance value can be converted to the signal be directly proportional to thing position.Instrument can hole capital after selling all securities debugging.Application in solid is measured can use the high frequency sensors of K-frequency range.
But existing radar levelmeter exists, owing to being difficult to resolve echoes signal, so be difficult to the height determining to feed, be unfavorable for the measurement of high work loading height; Simultaneously when radar levelmeter is measured on time, himself can not automatic alarm.
