Storage tank non-contact magnetostrictive displacement sensors provide reliable level and displacement measurement for petrochemical, water treatment, and process storage applications. Because the sensing element does not touch the moving float magnet, the design reduces wear and supports long-term stability in dirty or viscous media.

Typical models are defined by measuring range, probe length, and output type. Common specifications include a range from 300 mm to 20,000 mm, resolution of 0.1 mm, accuracy of +/-0.05% FS or +/-1 mm, and repeatability of +/-0.5 mm. Supply voltage is often 24 VDC, with output options such as 4-20 mA, HART, RS485 Modbus, or SSI. Process connection choices include flange, thread, and sanitary fittings, while wetted parts may be 304/316L stainless steel.

For storage tanks, select an explosion-proof model when required, with IP67 or IP68 protection, media temperature from -40 degC to 120 degC, and pressure ratings matched to tank conditions. Installation should keep the probe vertical, avoid turbulence and fill streams, and confirm the float is compatible with liquid density. Model codes usually indicate probe length, output, connection, and certification. Correct model and specification selection ensures accurate inventory monitoring, overfill protection, and stable operation. Accessories such as mounting brackets, floats, and junction boxes should be ordered with the correct model code to simplify installation and maintenance. Ensure correct use.
