Official product documentation for SEGMENsensor magnetostrictive sensors. Covering liquid level and linear position applications — explosion-proof, hydraulic cylinder, and corrosion-resistant variants.
The SEGMENsensor magnetostrictive downloads page holds 14 PDF datasheets for the SGM and SE series, covering linear position sensors, in-cylinder sensors and liquid level transmitters from 25 to 8000 mm. Each datasheet contains the specification table, dimensions, pin assignment and full ordering code; downloads require no registration.
High-accuracy magnetostrictive liquid level measurement for fuel storage tanks, chemical vessels, and process industry applications. Float-based non-contact sensing principle eliminates wear. Flameproof SE-LX10 / SE-LX20 / SE-LX30 and the PP / PFA SGM-LC10 cover hazardous and corrosive media.
On each series page the part-number builder can also create a one-page PDF datasheet for the exact part number you configure.

This page provides the complete documentation library for SEGMENsensor magnetostrictive sensors. Available documents include one two-page datasheet per SGM / SE series (specifications, wiring, dimension drawings and ordering code); CE declarations, RoHS statements, Modbus RTU register maps and SSI settings are supplied on request. Each datasheet covers both the magnetostrictive liquid level and linear position sensor variants.
Engineers rely on these documents for installation planning, control system integration, mechanical interface design, and regulatory compliance sign-off. The dimensional drawings include thread sizes, body lengths, float clearance requirements, and connector pinouts. SSI protocol guides detail timing diagrams and bit-field layouts needed for PLC programming.
Replacing a magnetostrictive sensor that is already installed? Match stroke, output, mounting thread and connector on the magnetostrictive sensor replacement cross-reference, then download the datasheet of the matching series here.
All documents are available to download — no registration required. For STEP files, DXF drawings, or certificates not listed here, contact info@segmensensor.com with your model number for delivery within 24 hours.

Magnetostrictive sensors deliver absolute position measurement without requiring homing or recalibration after a power cycle. The following applications represent the most common integration scenarios covered in SEGMENsensor technical documentation.
Hydraulic Cylinder Position Control: Rod-style magnetostrictive sensors mount inside hydraulic cylinders to provide real-time piston position feedback for closed-loop servo control in mobile machinery, injection moulding machines, and hydraulic presses. SSI (SGM-PR10) or RS485 output connects directly to servo drives and controllers.
Fuel and Chemical Tank Level Monitoring: Float-based magnetostrictive level transmitters measure liquid levels in storage tanks containing fuel oil, diesel, chemicals, and water with repeatability down to ±0.005 mm (SGM-LS10). 4–20 mA and RS485 Modbus RTU outputs integrate directly with SCADA and tank management systems.
Hazardous Areas: the intrinsically safe SE-PR30 position sensor and the flameproof SE-LX10 / SE-LX20 / SE-LX30 level transmitters are used in chemical plants, tank farms and solvent storage. The certificate and marking for the ordered model are confirmed with the order.
