JFA981 -- JFA986 silos solid high frequency radar level meter

measuring distance is up to 80m. Antenna is further optimized,
so that the new microprocessor can perform signal analysis at a higher rate.
applied in reaction still, silos for solid materials etc.

Category: radar level sensor/meter

产品描述标题.jpg

       The radar level antenna emits narrower microwave pulses and is transmitted down the antenna. 

       measuring distance is up to 80m.microwave exposure to the surface of the measured 

       medium is reflected back again by the antenna system to receive the signal transmission to 

       the electronic part of the automatic conversion into the level signal (because the microwave 

       propagation speed is extremely fast, the electromagnetic wave reaches the target and the reflection 

       back to the receiver back and forth The time used is almost instantaneous).


特点标题.jpg

       1 Small Antenna,easy to setall,Non-contact radar, no wear, no pollution.

       2 Almost unaffected about corrosion and foam,water vapour, temperature and pressure.

       3 Severe dust environment almost without influence on high frequency level meter

       4 The wavelength is shorter and will be have better reflection on the slanted solid surface.

       5 The beam Angle is small and the energy concentration, which enhances the echo capability 

          and avoiding the interference

       6 Blind area range smaller the measure effect will be better

       7 high signal-to-noise ,even in the case of volatility can obtain better performance
