Abstract

Monitoring systems play an essential role in enhancing safety, efficiency, and productivity, as well as providing the basis for decision-making and process control. This research aims to design a temperature monitoring system for a heat pipe evaporator prototype using a type-K thermocouple sensor, integrated with LabVIEW 8.5 as the graphical user interface (GUI). Monitoring data are stored automatically in file format for further analysis. The data acquisition system employs the NI 9213 16-Channel 24-Bit Thermocouple Input module and c-DAQ NI 9185. The experimental method consists of several stages, including planning, design, testing, and performance analysis. Characterization was carried out with 40% fluid volume at an initial temperature of 30 °C, with a maximum limit of 65°C according to the acquisition module specifications. Validation was performed using an STC 1000 controller with a resolution of 0.5°C.

Abstrak

Sistem monitoring berperan penting dalam meningkatkan aspek keamanan, efisiensi, dan produktivitas, serta menjadi dasar dalam pengambilan keputusan dan pengendalian proses. Penelitian ini bertujuan merancang sistem monitoring temperatur prototipe evaporator heat pipe menggunakan sensor termokopel tipe-K yang diintegrasikan dengan LabVIEW 8.5 sebagai graphical user interface (GUI). Data hasil monitoring disimpan secara otomatis dalam bentuk file untuk keperluan analisis lebih lanjut. Sistem akuisisi data memanfaatkan modul NI 9213 16-Channel 24-Bit Thermocouple Input dan c-DAQ NI 9185. Pengujian dilakukan dengan metode eksperimen melalui tahapan perencanaan, perancangan, pengujian, serta analisis kinerja alat. Karakterisasi dilakukan pada kondisi fluida sebesar 40% dengan suhu awal 30°C, serta batas maksimum temperatur 65°C sesuai spesifikasi modul akuisisi data. Validasi dilakukan dengan STC 1000 yang memiliki resolusi 0,5°C.
