This K-type thermocouple amplifier is the ideal solution for precise temperature measurements in demanding applications. With its ability to significantly amplify the weak signal of a thermocouple, it enables reliable sampling by most ADCs (analog-to-digital converters). The integrated temperature sensor provides automatic cold junction compensation, while the fixed gain factor converts the thermocouple voltage into an easily interpretable 5 mV/°C output voltage.
Key features:
- Accurate temperature measurement: supports thermocouples and provides an accurate output voltage proportional to the measured temperature.
- High common mode rejection: Minimizes interference caused by long leads or external influences.
- High impedance input: Enables additional filtering and ensures maximum signal stability.
- Wide temperature range: With a 5V supply, the amplifier covers temperatures up to 1000 °C.
