Official product documentation for SEGMENsensor magnetostrictive sensors. Covering liquid level and linear position applications — explosion-proof, hydraulic cylinder, and corrosion-resistant variants.
High-accuracy magnetostrictive liquid level measurement for fuel storage tanks, chemical vessels, and process industry applications. Float-based non-contact sensing principle eliminates wear. Explosion-proof ATEX/IECEx and PFA anti-corrosion variants available for hazardous and aggressive media.
Absolute linear position sensing for hydraulic cylinders, industrial automation, and machine tool positioning. Rod (R), housing (H), and external (E) form factors. Built-in ATEX/IECEx ratings available. Immune to vibration, shock, and EMI — suitable for demanding industrial environments.
This page provides the complete documentation library for SEGMENsensor magnetostrictive sensors. Available documents include product datasheets, CE declarations of conformity, UKCA certificates, RoHS compliance statements, ATEX/IECEx explosion-proof certificates, dimensional drawings, Modbus RTU register maps, and SSI/Start-Stop protocol guides. 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.
All documents are free to download — no registration required. For STEP files, DXF drawings, or ATEX certification packages 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 or Start-Stop output connects directly to standard servo drives.
Fuel and Chemical Tank Level Monitoring: Float-based magnetostrictive level transmitters measure liquid levels in storage tanks containing fuel oil, diesel, chemicals, and water to ±0.5 mm accuracy. 4–20 mA and RS485 Modbus RTU outputs integrate directly with SCADA and tank management systems.
Hazardous Area Position Sensing: ATEX Zone 1 / IECEx certified variants operate safely in explosive gas atmospheres (IIC group) at temperature class T6, used in offshore platforms, chemical plants, and solvent storage facilities where explosion-proof housings are mandatory.
