ALC6000 Smart RF Capacitive level transmitter
ALC6000 transmitter series are used in continuous measurement of RF capacitive material level. This capacitive level transmitter is widely applied almost all kinds of industry. Measurement detector and vessel make up a capacitor. The change of material level could produce the change of capacitive., the change of capacitive could analyze for handling and then transform a level signal.
Strong adaptability: the product could reliablely work under the formidable inviroment, such as high temperature, strong corrosion, strong adhesion, large dust etc.
The indication s of position is simple.
No need to maintenance: because of simple sensor structure and without movable part, the product no need to maintenance as it work.
The component of product
process connection and detector.
shell+4-20mA HART intelligent board
the introduction of measurement detector
the company offer many kinds of detectors which apply for continuous level transmitter. In spite of the measurement technology is same, but different detector design is suitable to different application.
For the choice of RF capacitive level is effected by many elements, such as electric, chemical, machanical.
The electric element: needing to offer earthing referred electrode such as the metal container skin, steel bar of reinforce concrete. The distance of the detector(main electrode) and earth electrode(referred electrode) could not surpass 200mm, if the distance surpass, please add assistant electrode or apply bipolar electrode detector. The medium with low viscocity and low dielectric should add coaxial . And the medium with high viscocity and low dielectric should apply bipolar electrode.
The chemical element: the material of the detector must be compatible with the process medium,and could not be rusty by the corrosion medium, and at the same time having no pollution for the medium.
The machancial element: the detector should bear the highest pressure and highest temperature of application site. In addition, stirring, thickness,viscosity,abrasion and installation configuration also affect the choice of detector. If the length of detector surpass 6m or space limit need to choose the lithe cable and avoid to apply rigid bar.
