A High Temperature Measuring Device Development for Die Casting Molten Metal Deposition
Background/Objectives: International market competitive power but also to expect importing substitution effect. Methods/Statistical Analysis: A temperature measuring device connected to a R-type thermocouple (temperature range 0℃ to 1,700℃) displays detected temperature using Flexible Number Display (FND). The device not only can use an external power employing an external adapter (9Vdc constant voltage, 400mA) but also can be operated by a built-in battery (four AA size, 1.2Vdc). Findings: A high temperature measuring device for die casting molten metal deposition is designed a firm-ware in this study by adapting Marvel Cinematic Universe (MCU) that is the core part of operation control using Cortex-40. For the purpose of targeted corporate clients domestic or abroad, the device using Cortex-M0 as a MCU is designed with the capability of measuring temperature having an accuracy range ±1℃ between 400℃ and 1700℃ within 6 minutes. This makes it possible for customers to purchase at lower cost. A measuring error must be necessary to reduce within ±1℃ when measured high temperature (400℃ ~ 1700℃). Also the additional function of measuring temperature ranging from a communication functional circuit, a detecting function for the short circuit and removal of sensor, a correction function for the temperature, an error detecting function, to a testing function is developed.
