Weatherproof and Explosion-Proof or Plastic Corrosion-Resistant Enclosures
Isolated 4-20 mA Output, Field-Selectable Direct or Reverse Acting
Enhanced Anti-Coating Sensitivity
Compatible with a Variety of Sensing Elements (LV5000 through LV5603)
产品描述
The LV590 Series has been discontinued. Please see the
LV3000/LV4000 Series as a possible alternative or contact our Flow Engineering department.
The LV5900 series radio frequency level transmitter is designed for continuous level measurement of conductive and
non-conductive liquids, granular materials, slurries and interface applications. The electronics incorporate an “anti-coat”
capability to compensate for the effect of conductive coatings which may build up on the sensing element surface.
(Use the LV5200 Series elements, page K-31, for conductive coating liquids.) The 4-20 mA output is isolated and has an
adjustable damping for turbulent level monitoring. The analog output is field-selectable for direct or reverse operation.
The blind transmitters can be remotely mounted up to 15 feet from the sensing element. Three accessories required are a
threaded adaptor, LV5971, which screws into the bottom of the enclosure to provide a surface mount; an explosion-proof
junction box, LV5972, which mounts onto the level element in place of the transmitter; and a triaxial cable,
LV5974-10 or 15 feet, to connect the junction box to the transmitter.
