Series_LS_Level_indicator_switch_&_transmitter - 2

Working principle glass tube indication, flanged connection A float connected to a guide tube with an internal magnet assembly on its side moves along a chamber, changing its height according to the level of a liquid inside a tank. magnetic strips indication, flanged connection glass tube indication, threaded connection magnetic strips indication, threaded connection The float is designed for the specific working liquid density. The internal magnet assembly couples with an external float or with a magnetic strips rail mounted externally and isolated of the level gauge chamber, providing an...

Level gauges Series LS Float types The selection of the float for each application is made according to the specific application conditions, such as liquid density and height to be measured. The diameter of the selected float determines the minimum connection size required for the correct installation of the series LS level gauge as well. Please consult factory.

 TR3420Ex hazardous area version ATEX Ex ia IIC T4 or T6 Transmitter composed of a resistive sensor based on a reed and resistances chain, mounted on a printed circuit placed inside a guide tube. Not wetted by the process liquid.  TR2420H (HART protocol), TR2420P (Profibus protocol) or TR2420F (Fieldbus protocol). Also available in combination with their Ex ia versions Variations in level inside the tank move the internal magnet assembly of the LS or LSL indicator, which by means of magnetic coupling changes the value of the resistance of the resistive sensor in correspondence to the...
