Toward a New Standard for Inclinometers.
Tokyo Keiki’s proposal.
Installation of an electronic inclinometer is mandatory on certain vessels*.
The TI-100 series is a high-precision electronic inclinometer developed by Tokyo Keiki, drawing on decades of expertise in marine instruments.
It fully complies with IMO performance standards and has obtained MED type approval.
In addition, its high visibility LCD display supports safer navigation on board your vessel.
＊Applicable to container ships and bulk carriers of 3,000 gross tonnage or more constructed on or after January 1, 2026

Optimum control machine position for curved pipe jacking
The north seeking gyrocompass is an absolute directional sensor that detects direction from the North Pole. This sensor has been used with extremely satisfactory results in curved pipe jacking systems.Real time machine coordination and position can be determined by absolute direction and distance data. This systems allows drastic reduction in survey work.

The TL-300 Series Level Sensing System for Smooth Excavation with Shield and Pipe Jacking Machines.Cities have recently introduced more underground tunnels as a way to ease aboveground congestion. This has led to increased demand for sophisticated technology in the field of tunnel excavation. When connected to our TMG Series Attitude Sensing System, the TL-300 Level Sensing System continuously measures changes in the level of shield and pipe jacking machines during the excavation process.This combination assures accurate control which is so vital to tunneling, especially along fragile natural slopes.

UW-30P is designed under the concept of ‘manual-less’, featuring an on-screen guide that displays setup instructions. Significant improvements in sensor installation allow users to operate the device without prior experience.

Model ES-180, the newest in the ES series, is a compact and popular gyrocompass.
