Integrated temperature measuring instrument for cylinder exhaust temperature measurement of marine internal combustion engines

Abstract

The present invention pertains to a thermometer. More specifically, a thermometer for measuring the temperature of a cylinder exhaust gas of an internal combustion engine for a ship includes: a first sensor rod for sensing temperature; a mechanical temperature measuring sensor coupled with the first sensor rod and having a temperature display indicating measured temperature; a second sensor rod inserted into the first sensor rod; an electric temperature measuring sensor formed at the upper portion of the second sensor rod and having a port to be connected to the outside; and a PID compensating circuit connected to the port so as to compensate temperature.

Description

technical field [0001] The invention relates to a temperature measuring instrument. The integrated temperature measuring instrument for measuring the cylinder exhaust temperature of an internal combustion engine for a ship integrates a mechanical temperature measuring sensor and an electrical temperature measuring sensor, and can measure the electrical temperature caused by temperature changes. The temperature deviation between the actual temperature of the measuring sensor and the measured temperature is compensated. Background technique [0002] In the existing technology, in order to measure the cylinder exhaust gas of the internal combustion engine used in ships, the mechanical temperature measuring instrument is installed and fixed adjacent to the electrical temperature measuring instrument. The on-site staff recognizes the temperature through the mechanical temperature measuring instrument, and the central control The room recognizes the temperature provided by the ele...

Problems solved by technology

[0005] Therefore, the temperature value of the electrical temperature measuring instrument and the temperature value of the mechanical temperature measuring instrument will greatly deviate due to the rapid high-temperature discharge of the cylinder exhaust gas of the marine internal combustion engine.

[0006] Moreover, in the prior art, the mechanical temperature measuring instrument and the electrical temperature measuring instrument are installed separately, which not only wastes time, but also is inconvenient in terms of space selection.
