雷達(dá)物位計(jì)發(fā)射功率很低的極短的微波通過天線系統(tǒng)發(fā)射并接收。雷達(dá)波以光速運(yùn)行。運(yùn)行時(shí)間可以通過電子部件被轉(zhuǎn)換成物位信號(hào)。一種特殊的時(shí)間延伸方法可以確保極短時(shí)間內(nèi)穩(wěn)定和精確的測(cè)量。即使存在虛假反射的時(shí)候，的微處理技術(shù)和軟件也可以準(zhǔn)確地分析出物位回波。通過輸入容器尺寸，可以將上空距離值轉(zhuǎn)換成與物位成正比的信號(hào)。儀表可以空倉(cāng)調(diào)試。在固體測(cè)量中的應(yīng)用可以使用K-頻段的高頻傳感器。由于信號(hào)的聚焦效果非常好，料倉(cāng)內(nèi)的安裝物或倉(cāng)壁的粘附物都不會(huì)影響測(cè)量。
The radar level meter emits and receives extremely short microwaves with low power through an antenna system. Radar waves travel at the speed of light. The running time can be converted into level signals through electronic components. A special time extension method can ensure stable and accurate measurements in an extremely short period of time. Even in the presence of false reflections, the latest microprocessing techniques and software can accurately analyze the level echoes. By inputting the container size, the distance value above can be converted into a signal proportional to the level of the object. The instrument can be debugged empty. The application in solid-state measurement can use high-frequency sensors in the K-band. Due to the excellent focusing effect of the signal, the installation materials inside the silo or the adhesion of the silo wall will not affect the measurement.

Guided wave radar level meter
導(dǎo)波雷達(dá)物位計(jì)的微波脈沖沿著一根纜、棒或包含一根棒的同軸套管運(yùn)行，接觸到被測(cè)介質(zhì)后，微波脈沖被反射回來，并被電子部件接收，并分析計(jì)算其運(yùn)行時(shí)間。微處理器識(shí)別物位回波，分析計(jì)算后將它轉(zhuǎn)換成物位信號(hào)給出。由于測(cè)量原理簡(jiǎn)單，可以不帶料調(diào)整，從而節(jié)省了大量調(diào)試費(fèi)用。測(cè)量纜或棒可以截短，使之更加適應(yīng)現(xiàn)場(chǎng)的應(yīng)用。對(duì)于蒸汽不敏感，即使在煙霧、噪音、蒸汽很強(qiáng)烈的情況下
The microwave pulse of the guided wave radar level meter runs along a cable, rod, or coaxial sleeve containing a rod. When it comes into contact with the measured medium, the microwave pulse is reflected back and received by electronic components, and its operating time is analyzed and calculated. The microprocessor recognizes the level echo, analyzes and calculates it, and converts it into a level signal to provide. Due to the simple measurement principle, it can be adjusted without material, thus saving a lot of debugging costs. The measuring cable or rod can be shortened to make it more suitable for on-site applications. Not sensitive to steam, even in conditions of strong smoke, noise, and steam
