TIPD161
類比線性化 3 線 PT100 RTD 至 2 線 4-20mA 電流迴路發送器參考設計
TIPD161
概覽
This design features a single-chip solution to linearize and transmit a 3-wire PT100 RTD over the industry standard 2-wire 4-20mA current loop. The design was configured for a -200°C to 800°C temperature range, but other temperature ranges can be achieved by adjusting the component values as discussed in the Theory of Operation section of the reference design guide.
特點
- Input: 3-Wire PT100 RTD
- Temperature Range: -200°C to 800°C
- Output: 2-Wire 4-20mA Current Loop
- Includes analog RTD sensor linearization for >40x linearity improvement over end-point fit
- Reference design includes theory, calculated error analysis, component selection, PCB layout, and measured results.
