X623 Intrinsically safe large angle submersible tilt sensor
Robust tilt sensor for underwater and hazardous gas environments. Designed for demanding underwater feedback tasks up to 350 bar pressure.
Key features
- Intrinsically safe to ATEX / IECEx / UKEX
- Sealed to IP68, submersible up to 350 bar
- Factory calibrated angle range up to 160°
- Highly stable and accurate inductive technology
- Wet-mate connector for reliable underwater use
- Designed for ROVs and offshore subsea systems
Performance highlights
The X623 is a compact, high-performance submersible tilt sensor designed for underwater environments where explosive gases or vapors may be present. Built with non-contact inductive technology, it provides a linear, high-accuracy analog output proportional to angle rotation. The sensor ensures stability and repeatability over wide temperature ranges.
Usage conditions
This sensor is certified intrinsically safe according to ATEX, IECEx, and UKEX for gas/vapor (Zone 0–2) applications and is operable in temperatures from -40 °C to +80 °C. With sealing rated to IP68 at 350 bar and robust stainless steel housing, the X623 thrives in deep-sea and hazardous installations.
Possible applications
- Remotely operated underwater vehicles (ROVs)
- Offshore subsea monitoring systems
- Pipeline inspection equipment
- Underwater robotics
- Marine energy installations
- Deep well monitoring
Advantages of choosing this product
With its rugged build, high ingress protection, and intrinsic safety, the X623 offers unmatched performance in hazardous, high-pressure underwater environments. The sensor's wet-mate connector ensures secure electrical connections even in submerged use. Althen offers customer-specific calibration and complete system integration support.
