Texport Imabari Exhibition Hall
We will show new ship performance monitor at booth No. F-38.



Shaft horsepower meter is an instrument designed to determine the horsepower delivered from the engine to the propeller on a vessel by measuring the torsion of the rotating shaft.


Shaft thrust load is calculated by measuring the compressive (lengthwise) strain on the shaft. SEC has developed a high precision shaft thrust load meter based on the measurement technology created when making the shaft horsepower meter. There are three types of SEC Shaft Trust Load Meter: Separate type, combine type and temperature correction type.


The SEC engine combustion pressure sensor measures the full stroke pressure of compression, combustion, and expansion with a very unique detection method that replaces pressure with changes in the natural frequency of the metal strip.
The newly manufacturing and sales is stopped.
The maintenance is continued but for the details please contact us.
