Level transmitters Series LE Float level transmitter for liquids Simple construction Top mounted, or side mounted by means of external chamber Watertight and safe installation Excellent chemical resistance Measuring range: 150 mm … 6 m Resolution: 10 mm Connections: - EN 1092-1 flange. Other flange standards on request (ANSI, JIS,...) - Threaded connections BSP or NPT Materials: EN 1.4404 (AISI 316L), PVC, PP, PVDF, PTFE Level transmitter: - 4-20 mA analog output for safe or hazardous area (Ex ia IIC T4 or T6 protection, ATEX certified). HART, PROFIBUS, FIEL

Working principle By means of float with magnetic field and reed chain. A reed switches / resistance chain is mounted inside a guide tube. The changes in liquid level modify the float position in this guide tube, so that it activates the reed switches providing an output signal of variation of resistance, which can be later converted into an analog output of voltage or current. - PTFE, PVDF:  Ambient temperature: - EN 1.4404 (AISI 316L): - PTFE, PVDF:  Working pressure: - EN 1.4404 (AISI 316L) and PVC / PP / PTFE with AISI 316L inside: PN16 - PVC / PP / PTFE: PN10 Others on request Applications...

Level transmitters Series LE Transmitters Transmitter composed of a resistive sensor based on a reed and resistances chain, mounted on a printed circuit placed inside a guide tube. Variations in level inside the tank move the float, which by means of magnetic coupling changes the value of the resistance of the resistive sensor in correspondence to the measured liquid level. These variations of resistance are processed by an electronic converter in order to obtain a 0 ... 4-20 mA current output proportional to liquid level.
