We would like to introduce our "Combustion Pressure Sensor." The pressure receiving part is not a diaphragm structure, but a pipe structure with a closed upper end. There is a certain proportional relationship between the applied pressure and the change in the natural frequency of the membrane, and pressure is calculated from the change in frequency. Additionally, we have minimized the size of the electrical components used, enhancing reliability. 【Features】 ■ The coil unit is mounted in a housing with cooling fins. ■ The housing is fixed to the outer cylinder via insulation material. ■ It suppresses temperature rise in the housing body, allowing for stable operation. ■ Super stainless steel is used for the pressure receiving cylinder and inner core, increasing durability. *For more details, please refer to the PDF document or feel free to contact us.

The "SEC Thrust Load Meter" detects extremely small axial compressive strain using a super high-sensitivity displacement sensor with a minimum resolution of 0.025 microns. By correcting the torsional component of the axis using torque data obtained from the SEC Shaft Power Meter, it is possible to measure the axial thrust load with high precision. We offer an "integrated type" that measures both the shaft power meter and thrust load meter with a single detection ring, as well as "independent type" and "temperature compensation type." 【Features】 ■ Measures axial pressure (longitudinal) strain caused by propeller thrust ■ Detects extremely small axial compressive strain with a super high-sensitivity displacement sensor ■ Capable of measuring axial thrust load with high precision ■ Available in integrated, independent, and temperature compensation types *For more details, please refer to the PDF document or feel free to contact us.

The "SEC Shaft Power Meter" is an instrument that measures the transmitted horsepower supplied from the engine to the propeller (in the case of ships) by measuring the twist of the rotating shaft. It can also be installed on operating vessels. For operating vessels, installation at port is also supported. The data processing display unit offers a dedicated monitor for single-axis measurement, the "LED type," and a monitor compatible with two or more axes and shaft thrust load measurement, the "LCD type." 【Features】 ■ The sensitivity determination accuracy of the sensor is ±0.15% ■ The sensitivity characteristics of the sensor remain unchanged for a semi-permanent period ■ The metal film used in the sensor has exceptionally excellent repeat stress characteristics ■ Installation on operating vessels is possible ■ For operating vessels, installation at port is also supported *For more details, please refer to the PDF document or feel free to contact us.

The "Engine Combustion Pressure Monitor" monitors the entire process of engine cylinder pressure and combustion pressure. It detects changes in the engine's cylinder pressure using a pressure sensor that converts these changes into variations in the natural frequency of a metal membrane. By graphically displaying data such as P-θ diagrams and P-V diagrams, it is also possible to monitor visually. Additionally, simultaneous and continuous monitoring of all cylinders is possible, allowing for the observation of combustion conditions by cylinder and by time. 【Features】 ■ Compatible with diesel and gas engines (2 or 4 cycles) ■ Can measure up to 18 cylinders simultaneously ■ Crankshaft rotation speed: capable of handling up to 1000 RPM ■ Crank angle detection: 2-cycle every 0.25 degrees / 4-cycle every 0.5 degrees ■ Measurement accuracy: +1.2% / -0.5% *For more details, please refer to the PDF document or feel free to contact us.
