Material tank rod-type magnetostrictive level gauges provide reliable continuous level measurement for liquids in chemical, water, food, and storage tanks. A typical model combines a stainless steel probe rod, a magnetostrictive sensing element, and a float. The float position is converted into a precise 4-20 mA, HART, RS485, or Modbus signal for control systems.

Key specifications usually include a measuring range from 300 mm to 6000 mm, accuracy of +/-1 mm or +/-0.05% FS, resolution of 0.1 mm, and repeatability of 0.05% FS. Process connections can be flange, thread, or sanitary clamp. Wetted materials may be 304/316L stainless steel, PTFE, or PVDF for corrosive media. The gauge can handle process temperatures from -40 degC to 150 degC and pressures up to 2.5 MPa, depending on probe and flange rating.

Model selection should consider tank material, media density, viscosity, chemical compatibility, explosion-proof requirements, and output type. Common protection grades are IP65/IP67, with Ex d or Ex ia options for hazardous areas. Rod-type designs install through the tank top and suit narrow tanks where compact measurement is needed.

Before ordering, confirm insertion length, float type, flange standard, power supply (24 VDC), and display or communication needs. Proper grounding and avoidance of strong magnetic interference ensure stable performance. With correct model and specification matching, the gauge delivers long-term accuracy, low maintenance, and safe level monitoring for material tanks.
