G130 Long stroke in-cylinder linear position sensor

Intrinsically safe linear position sensor with long stroke capabilities, designed for hydraulic or pneumatic cylinder applications in hazardous areas.


Key features

  • Intrinsically safe for hazardous gas/vapour zones
  • Non-contact inductive technology eliminates wear
  • High durability and stability over wide temperature ranges
  • Custom stroke lengths from 0–1485 mm
  • Compact stainless steel body with IP65/IP67 sealing
  • Compatible with Althen G005 galvanic isolation amplifier

Performance highlights G130 Long stroke in-cylinder linear position sensor

The G130 long stroke in-cylinder position sensor uses non-contact inductive technology to deliver precise, wear-free position measurement. Designed for integration into hydraulic and pneumatic cylinders, it ensures high repeatability and excellent linearity across custom stroke lengths up to 1485 mm.

Usage conditions

Built with rugged stainless steel and a fluoropolymer-sheathed probe, the G130 operates reliably in demanding industrial environments. Certified intrinsically safe (Ex ia IIC T4 Ga), it is ideal for Class I, Zone 0 and Division 1 hazardous locations. Sealing options up to IP67 ensure protection in wet or dusty conditions.

Possible applications

  • Hydraulic cylinder position feedback
  • Pneumatic actuators
  • Oil & gas exploration equipment
  • Process automation in hazardous areas
  • Energy sector (e.g., refineries, offshore rigs)

Advantages of choosing this product

The G130 offers exceptional design flexibility with customized travel lengths, infinite resolution, and high resistance to shock and vibration. With intrinsic safety certification and seamless integration with the Althen G005 amplifier, it's the ideal sensor for safety-critical and high-reliability environments.
