MLX90614 General Description

The MLX90614 is an Infra Red thermometer for non contact temperature measurements. Both the IR sensitive thermopile detector chip and the signal conditioning ASIC are integrated in the same TO-39 can.
Integrated into the MLX90614 are a low noise amplifier, 17-bit ADC and powerful DSP unit thus achieving high accuracy and resolution of the thermometer.

The thermometer comes factory calibrated with a digital SMBus output giving full access to the measured temperature in the complete temperature range(s) with a resolution of 0.02°C.

The user can configure the digital output to be PWM. As a standard, the 10-bit PWM is configured to continuously transmit the measured temperature in range of -20 to 120 °C, with an output resolution of 0.14 °C.

Berikut ini adalah sensor temperatur NTC K524 yang ditemukan di Jaya Plaza. Harganya lumayan murah, di bawah Rp 10 ribu.

Pengukuran di temperatur 24 derajat Celcius menghasilkan resistansi 41.6 ohm.

Sensor dihangatkan dengan cara digenggam dengan tangan, hasilnya resistansi turun ke 33 ohm. Temperatur tangan kira-kira sekitar 35 derajat celcius menurut termometer GM320.

Spesifikasi NTC K524 menurut http://en.tdk.eu/tdk-en/176900/products/application-guides/consumer—epcos-brand/home-appliances/ignition-units-for-gas-cookers/ntc-thermistors adalah sebagai berikut:

WATTAGE AND APPLICATION

HOW TO SOLDER

1. Clean the parts to be joined.
2. Clean soldering iron tip and tin all faces of tip with a coating of solder.
3. Heat parts (not solder) to be joined.

a



C870 ini adalah sebuah sensor temperatur PTC (Positive Temperature Coefficient), artinya makin panas maka makin besar resistansinya. Menurut datasheetnya, komponen ini umumnya dipakai sebagai pembatas arus. Mekanismenya adalah arus pada PTC menghasilkan panas, dan panas ini akan menaikkan nilai resistansinya. Jika nilai resistansi tinggi, maka arus yang mengalir akan berkurang.

4. Apply flux core solder to heated parts, not the soldering tip, and heat it till solder melts and flow freely.    ‘
5. Don t apply too much solder unnecessarily.

CAUTION
When the power is on, the tip temperature can reach over 300°C CS72°F). Since mishandling may lead to  burns or fire, be sure to comply with the following precautions.

• Do not touch the tip and the metalic parts near the tip.
• Do not use the product near flammable items. Unplug when the unit is not in use.
• Do not warm up the soldering iron with the tip pointing down.
• Do not use the unit for applications other than soldering.
• Do not wet the unit or use the unit when your hands are wet.
• Do not modify the unit. Use only genuine DEKKO replacement parts.
• Do not shock the unit, or otherwise subject the heating element to severe damage.
• The soldering process will produce smoke, so make sure the area is well ventilated.
• Children should be supervised to ensure that they do not play with the DEKKO.

WARNING

• In order to avoid burns, do not attempt to touch except grip as the unit is hot. And do not leave the unit unattended.
• Do not attempt to use the unitaround combustible in order to prevent tires.

DAYA DAN APLIKASI

• 20 40W   : P.C. Board, I.C. Transistor , Chip
• 60 80W    :     Bagian Tombol  , Elektronik, Konektor  ,  Condensor    Trafo
• Diatas 100W:   Bila diperlukan      Kapasitas panas   besar

CARA MENYODER

1. Bersihkan bagian yang disolder.
2. Bersihkan ujung solder dan lapisi ujung solder dengan timah.
3. Panaskan bagian untuk disolder.
4. Beri timah pada bagian yang telah dipanaskan, bukan ujung solder, panaskan sampai cair dan rata.
5. Jangan beri terlalu banyak timah.

PERHATIAN
Ketika solder on, ujung solder bisa mencapai temperatur lebih dari 300°C (572*F). Penanganan
yang salah bisa menyebabkan luka bakar dan kebakaran, perhatikan hal-hal berikut:

• Jangan sentuh ujung dan bagian metal dekat ujung.
• Jangan digunakan dekat bahan yang mudah terbakar cabut ketika tidak dipakai.
• Hadapkan ujung solder ke atas <waktu pemanasan.
• Jangan dipakai selain untuk menyoder.
• Jangan sampai alat basah atau tangan basah.
• Jangan memodifikasi alat solder. Pakai pengganti DEKKOyang asli.
• Jangan menggoncang alat solder, bisa menyebabkan elemen pemanas rusak.
• Proses penyoderan mengeluarkan asap, pastikan ventjlasi ruangan memadai.
• Jauhkan alat DEKKO dari anak-anak.

PERINGATAN

• Untuk mencegah luka bakar, jangan menyentuh alat solder yang sendang panas. Dan jangan membiarkan alat solder tanpa terjaga.
• Jangan memakai alat solder di lingkurigan yang mudah terbakar untuk menghindari kebakaran
