Description

선박의 실린더 배기가스 온도측정용 온도계측기{Temperature measuring instrument for cylinder exhaust gas temperature of ship}Temperature measuring instrument for cylinder exhaust gas temperature of ship}

본 발명은 선박의 실린더 배기가스 온도측정용 온도계측기에 관한 것으로서, 보다 구체적으로는 기계식 온도계측센서와 전기식 온도계측센서를 일체화시켜 기계식 온도계측센서와 전기식 온도계측센서의 온도 편차를 보상할 수 있도록 하는 것은 물론이고, 계측기본체와 온도표시계를 이격시켜 측정자가 활동하기 좋은 넓은 공간에서 온도계측이 용이하게 제공될 수 있도록 한 선박의 실린더 배기가스 온도측정용 온도계측기를 제공코자 하는 것이다.The present invention relates to a thermometer for measuring the temperature of a cylinder exhaust gas of a ship, and more specifically, a mechanical thermometer sensor and an electric thermometer sensor are integrated to compensate for the temperature deviation between the mechanical thermometer sensor and the electric thermometer sensor. Of course, it is intended to provide a thermometer for measuring the temperature of the cylinder exhaust gas of a ship so that a thermometer can be easily provided in a wide space where the measurement body and the temperature indicator are separated from each other.

선박용 내연기관의 실린더 배기가스의 측정을 위하여 기계식 온도측정기와 전기식 온도계측기를 이웃한 상태로 설치 고정시켜 현장 작업자는 기계식 온도측정기를 통하여 온도를 인지하고, 중앙통제실은 전기식 온도계측기를 통하여 제공되는 온도를 인지하여 상황파악 및 돌발상황에 대처하였다.In order to measure the cylinder exhaust gas of the ship's internal combustion engine, a mechanical temperature measuring instrument and an electric thermometer are installed and fixed in a neighboring state, so that the field worker recognizes the temperature through a mechanical temperature measuring instrument, and the central control room is provided with an electric thermometer. Recognizing the situation and coping with unexpected situations.

그러나 기계식 온도측정기에서 제공되는 온도값과, 전기식 온도측정기에서 제공되는 온도값을 비교하여 보면, 전기식 온도측정기의 온도값과 기계식 온도측정기의 온도값에는 온도 측정부위가 다르고 각 측정기간의 응답속도 차이로 인한 편차가 발생하게 된다. 즉, 기계식 온도센서는 즉각적인 반응이 이루어지나, 전기식 온도센서는 시간차를 두고 반응이 이루어짐으로, 기계식 온도센서의 온도값과 전기식 온도센서가 측정한 온도값이 서로 상이하다는 문제가 있었다.However, when comparing the temperature value provided by the mechanical temperature measuring instrument and the temperature value provided by the electric temperature measuring instrument, the temperature value of the electric temperature measuring instrument and the temperature value of the mechanical temperature measuring instrument have different temperature measurement parts and the difference in response speed of each measurement period. There is a deviation due to. That is, the mechanical temperature sensor reacts immediately, but the electric temperature sensor reacts at a time difference, so there is a problem that the temperature value of the mechanical temperature sensor and the temperature value measured by the electric temperature sensor are different from each other.

따라서, 선박용 내연기관의 실린더 배기가스의 급격한 고온의 배출에 따른 전기식 온도측정기의 온도값과 기계식 온도측정기의 온도값에는 큰 편차가 발생하는 문제점이 있었으며, 기계식 온도측정기와 전기식 온도계측기를 따로 설치해야하므로 공간선정의 문제점도 있었다.Therefore, there is a problem that a large deviation occurs between the temperature value of the electric temperature meter and the temperature value of the mechanical temperature meter due to the rapid discharge of the cylinder exhaust gas of the ship's internal combustion engine, and the mechanical temperature meter and the electric thermometer must be installed separately. Therefore, there was also a problem of space selection.

이러한 문제점을 일소코자 본 발명자는 대한민국 등록특허공보(B1)10-1004117호(2010.12.27.)의 선박용 내연기관의 실린더 배기가스 온도측정용 일체형 온도계측기를 제시한 바 있다.In order to overcome this problem, the present inventors have proposed an integrated thermometer for measuring the temperature of cylinder exhaust gas of an internal combustion engine for a ship in Korean Patent Publication (B1)10-1004117 (2010.12.27.).

이의 구성은 선박용 내연기관의 실린더 배기가스의 온도를 측정하기 위한 온도계측기에 있어서, 온도를 감지하는 제1센서봉과, 상기 제1센서봉과 결합되어 계측 온도를 나타내는 온도표시계로 이루어지는 기계식 온도계측센서; 상기 제1센서봉의 내부에 삽입되는 제2센서봉과, 상기 제2센서봉의 상부에 형성되어 외부와 연결되는 포트로 이루어지는 전기식 온도계측센서; 상기 포트와 연결되어, 상기 전기식 온도 계측센서의 온도값을 보상하는 P.I.D보상회로;를 포함하도록 구성하고 있다.The configuration thereof is a thermometer for measuring the temperature of the cylinder exhaust gas of the internal combustion engine for ships, the first sensor rod for sensing the temperature, and a mechanical thermometer sensor consisting of a temperature indicator combined with the first sensor rod to indicate the measured temperature; An electric thermometer sensor comprising a second sensor rod inserted into the first sensor rod and a port formed on the second sensor rod and connected to the outside; And a P.I.D compensation circuit connected to the port to compensate the temperature value of the electric temperature measurement sensor.

상기한 선행기술의 경우 기계식 온도계측센서와 전기식 온도계측센서를 일체화시켜 휴대 및 설치가 용이하며, 전기식 온도계측센서와 P.I.D보상회로를 연결시켜 실제온도와 측정온도간의 온도편차를 보상하여 사용자가 실측의 보상온도를 인지할 수 있게 되며 기계식 온도계측센서와의 측정 편차를 없앨 수 있는 등의 효과를 제공하고 있다.In the case of the above-described prior art, it is easy to carry and install by integrating a mechanical thermometer sensor and an electric thermometer sensor, and by connecting the electric thermometer sensor and the PID compensation circuit, the temperature deviation between the actual temperature and the measured temperature is compensated for the actual measurement by the user. It is possible to recognize the compensation temperature of and to eliminate the measurement deviation from the mechanical thermometer sensor.

한편, 상기한 온도계측기의 경우 측정장소가 엔진으로부터 배기되는 배관쪽은 고온이며, 측정자의 출입이 어려운 장소인 경우 온도 측정 작업이 필요한 경우 작업에 매우 어려움이 있었던바, 현장에서는 이러한 문제점을 개선할 수 있는 신규한 구성의 온도계측지가 요구되고 있었다.On the other hand, in the case of the above-described thermometer, the pipe side where the measurement place is exhausted from the engine is high temperature, and in the case of a place where it is difficult for a measurer to enter, it is very difficult to work when a temperature measurement work is required. There has been a need for a new configuration of thermometry.
