SGM-LC10 is a magnetostrictive level sensor built for corrosive liquids. The head is PP and the float is PFA, rated in the datasheet for strong acids and strong alkalis. It measures 25–1000 mm continuously with 4–20 mA, 0–20 mA, 0–10 V, 0–5 V or RS485 output and IP68 sealing.
It is suitable for the new energy and chemical industries, and is used to measure the liquid level height in corrosive environments. Part number prefix SGM stands for the SEGMENsensor magnetostrictive range; the full ordering code is explained below and in the datasheet.
