SGM-LS10 is a stainless-steel rod magnetostrictive level sensor for continuous tank level. A float rides on the 304 stainless tube and the sensor reports its absolute position over 25–8000 mm with ±0.005 mm repeatability, as 4–20 mA, 0–20 mA, 0–10 V, 0–5 V or RS485, sealed to IP68 for indoor or outdoor tanks.
The stainless steel housing is suitable for liquid level measurement both outdoors and indoors. Part number prefix SGM stands for the SEGMENsensor magnetostrictive range; the full ordering code is explained below and in the datasheet.
