ada1778，原廠 Analog Output K-Type 熱電偶放大器模組 - AD8495 Breakout

 

　　Thermocouples are very sensitive, requiring a good amplifier with a cold-compensation reference. We have a couple digital thermocouple amplifiers in the shop already from Maxim. Now we're happy to introduce an excellent analog-output amplifier. This is a very simple sensor to use, and if your microcontroller has analog input capability, you'll be ready to go really fast!

　　The AD8495 K-type thermocouple amplifier from Analog Devices is so easy to use, we documented the whole thing on the back of the tiny PCB. Power the board with 3-18VDC and measure the output voltage on the OUT pin. You can easily convert the voltage to temperature with the following equation: Temperature = (Vout - 1.25) / 0.005 V. So for example, if the voltage is 1.5VDC, the temperature is (1.5 - 1.25) / 0.005 = 50°C

　　Each order comes with a 2 pin terminal block (for connecting to the thermocouple), a fully assembled PCB with the AD8495 + TLVH431 1.25V precision voltage reference, and pin header (to plug into any breadboard or perfboard). Goes great with our 1m K-type thermocouple (not included). Not for use with any other kind of thermocouple, K type only!

 

• Works with any K type thermocouple
• Uses the AD8495ARMZ part number (A graded chip)
• Will not work with any other kind of thermocouple other than K type
• Easy to use analog output
• Temp range with 5V power / 5V電源： -250°C to +750°C output (0 to 5VDC) as long as the thermocouple can handle that range
• Temp range with 3.3V power / 3.3V電源： -250°C to +410°C output (0 to 3.3VDC) as long as the thermocouple can handle that range

Note: The terminal blocks included with your product may be blue or black.

【Technical Details】：

• Sensing Accuracy Range： ± 1°C around room temperature, ± 2°C for −25°C to +400°C, beyond that range see the AN-1087 app note
• Supply Voltage： 3-18VDC

【Dimensions】：

• 尺寸：20mm x 16mm x 2mm / 0.8" x 0.6" x 0.08"
• Weight: 1.1g

【Revision History】修改：

• As of March 15, 2024 - We added a pre-soldered terminal block. / 添加了預焊接線端子。
• As of May 15, 2023 – we've updated this PCB with Adafruit Pinguin to make a lovely and legible silkscreen - you may get the new PCB or the older version with vector fonts - both are identical other than the fancy silkscreen.
