Why radar level transmitter can be widely applied in level measuring field

DATE: 2019-11-07
BROWSE TIMES: 6

Radar level transmitter is advanced level measuring instrument, whose maximum measuring range can be up to 70 meters. Whose Antenna have been further optimization, the new rapid microprocessor can undertake higher rate of signal analysis and processing, so that this transmitter can be used in the process of the solid material, containers or strong dust easily crystallized, condensation.


1.radar level transmitter applied in measuring the level of solid particle.

In cement plant,most of raw materials are granular materials, and some are blocky material, such as limestone, coal, shale etc. Whose bulk clinker are also granular materials, which are stored in a library or barn, there are material rest Angle and a reflection interface.According to the feeding and unloading material which is formed by the rest Angle and the surface, recommending non-contact type radar level transmitter, that is with bar or horn antenna level transmitter, if the effective range can be is determined.

If using the contact type, will generate a larger tension of cable, so that will cause an accident.Echo signal of the horn antenna will be stronger, and precision will be higher (plus or minus 0.2% to plus or minus 0.2% F.S),according to the information feedback from plant.

2.radar level transmitter applied in measuring the level of powder

Generally speaking, there are 4 ~ 8 piece in the cement plant and cement grinding station, in the cement plant, of fly ash and cement and raw meal homogenizing library, these materials are all powder, very difficult to measure the level of material.
The surface of curry powder is very loose , and reflecting microwave is very difficult, also can choose non-contact type horn antenna radar level transmitter with big flange.  Actually,the cable can be regard as antenna and also be guided wave tube, two beings become one.The microwave pulse will be propagated along the rope from the probe, and reflected back when pulse meet the material surface. the range can reach 35 m, the dielectric constant of the measured material epsilon minimum is 1.6.Alternatively, the maximum tension of cable can being abrasion and stand, who can satisfy all kinds detection requirements of powder requirements in the cement plant.

The professional suggestions of selection and most reliable radar level transmitter will be provided by Xi'an Dechuang Electrical Technology Co., Ltd.

    Guided wave radar liquid level gauge, a liquid level measuring instrument in industrial production, is based on the principle of time domain reflection (TDR) to complete the continuous level measurement of liquids, particles and slurries. Widely used in water storage tanks, acid and alkali storage tanks, slurry storage tanks, solid particles, small oil storage tanks, all kinds of conductive, non-conductive media, corrosive media such as coal bunkers, ash bunkers, oil tanks, acid tanks, etc. .So how to correctly choose the guided wave radar level gauge? Please see the following key points for selection: 1. Confirm the viscosity of the measuring mediumThe selection of guided wave radar level gauge must confirm the viscosity of the measurement medium. If the measurement medium is very vi...

    Air purge+Nuzzle ,  Universal joint:The necessary adjunct when measuring the level of bulk solid in silos bins and tanks.When continuous microwave radar level meter  measure the level of solid medium, such as grains, cement powders, sand, stone or others solid particles,  the solid material  will form a stockpile or hopper in the silo when feeding  or undloading. Then the antenna of the radar level transmitter need to perpendicularly alignment to the medium surface,  if the material is uneven,  and the heap angle is large then the universal joint flange is needed to adjust the horn angle to aim the charge level.(Due to the inclination of the solid surface it will cause the problem of  echo decay or even the signal loss.)        &#...
