G125 (Submersible) linear inductive sosition sensor
Compact, robust, and intrinsically safe linear sensor for high-pressure underwater and hazardous applications.
Key features
- Intrinsically safe: CSA-approved for hazardous gas areas
- Pressure-sealed: IP68 rated to 350 bar
- Linear output calibrated to customer travel
- Stainless steel construction for harsh environments
- Spring-loaded push rod options up to 300 mm
- Infinite resolution with excellent stability and repeatability
Performance highlights
The G125 submersible linear inductive position sensor offers exceptional reliability and accuracy for extreme underwater environments. With CSA approval for hazardous gas zones (Class I, Zone 0, Division 1), this sensor ensures safe and stable performance in high-risk conditions. Its linear output is calibrated to the customer's specific travel needs (5 mm to 800 mm) and maintains excellent linearity and frequency response.
Usage conditions
- Designed for underwater applications like ROVs and offshore installations
- Fully submersible with environmental sealing up to IP68 350 bar
- Operates in temperatures from -40°C to +80°C
- Requires use with a galvanic isolation barrier (e.g., Althen G005)
Possible applications
- Underwater remotely operated vehicles (ROVs)
- Oil and gas subsea installations
- Industrial automation in hazardous zones
- Marine hydraulic cylinder position feedback
- Subsea valve or actuator feedback
Advantages of choosing this product
By combining rugged stainless-steel housing, CSA intrinsic safety certifications, and high customizability, the G125 ensures long-term performance even under the most demanding conditions. Its small form factor and mounting flexibility make it ideal for retrofits or compact spaces.
