X114 Submersible stand-alone linear position sensor

Compact and rugged position sensor for demanding submersible applications. Designed with intrinsically safe technology for use in hazardous gas/vapour zones.


Key features

  • Intrinsically safe for explosive gas atmospheres
  • Non-contacting inductive measurement technology
  • Sealed to IP68 (10 bar) and IP69K
  • Custom travel range up to 800 mm
  • Stainless steel housing with EMC protection
  • Output: 0.5–4.5V ratiometric with 5V supply

Performance highlights

The X114 is a highly reliable linear position sensor engineered for applications where the device must operate fully submerged under pressure. With non-contact inductive technology and intrinsically safe EX07 electronics, it offers high linearity, stability, and long-term durability. Each sensor is custom-calibrated to the required travel length (5 to 800 mm).

Usage conditions

The sensor is certified for use in potentially explosive gas and vapour atmospheres (ATEX / IECEx / UKEX) with ambient temperature ratings from -40°C to +80°C. It features IP68 10 bar and IP69K sealing, ensuring operation in extreme environments.

Possible applications:

  • Submersible valve position feedback
  • Offshore and subsea equipment monitoring
  • Oil & gas pipelines and refineries
  • Chemical plants with ATEX zone classifications
  • Hydraulic and pneumatic actuators in hazardous areas

Advantages of choosing this product

  • Intrinsically safe operation ensures compliance in regulated environments
  • Durable stainless steel housing with high ingress protection
  • Precision-engineered for custom stroke lengths and demanding use cases
  • Maintenance-free with non-contact design eliminating mechanical wear
  • Full EMC protection for stable signal integrity

Other important features:

  • Output: 0.5–4.5V ratiometric (5V input)
  • Resolution: Infinite
  • Frequency response >10 kHz
  • MTBF: 350,000 hrs @ 40°C
  • Captive or free push rod with various end fittings
  • Optional spring loading for return action
