Performance highlights G114 Submersible linear inductive position sensor
The G114 is a compact, high-performance linear inductive position sensor designed for use in hazardous and submersible environments. With infinite resolution, excellent linearity (≤ ±0.25% FSO), and outstanding EMC protection, it provides precise position feedback even under harsh conditions.
Usage conditions
This sensor is fully submersible and intrinsically safe, certified for Class I, Zone 0, and Division 1 hazardous gas environments. With an IP68 (10 bar) and IP69K sealing rating, the G114 can operate underwater up to 100 meters. It performs reliably in temperatures from -40°C to +80°C, and features a robust stainless steel 316 housing.
Possible applications
- Subsea hydraulic cylinder monitoring
- Underwater vehicle actuator feedback
- Marine and offshore position detection
- Chemical plant valve positioning
- Dams and hydropower gate control
- Test rigs in explosion-hazard zones
Advantages of choosing this product
The G114 provides robust, wear-free inductive measurement in extreme conditions. Its custom travel lengths, various push rod and mounting configurations, and compatibility with the Althen G005 galvanic barrier amplifier make it a flexible and safe choice for OEM engineers and test system designers.
Other important features
- Captive or non-captive push rods
- Spring return options available
- Ratiometric 0.5–4.5 V analog output
- Compatible with 3-wire or 5-wire configurations
- CSA-approved for intrinsically safe installations
- MTBF of 350,000 hours at 40°C
