PRTD Conditioning Circuit and Temperature Controller

GENERAL DESCRIPTION The ADT70 provides excitation and signal conditioning for resistance-temperature devices (RTDs). It is ideally suited for 1 kΩ Platinum RTDs (PRTDs), allowing a very wide range of temperature measurement. It can also easily interface to 100 Ω PRTDs. Using a remote, low cost

PRTD调理电路和温度控制器

ADT70能够为电阻-温度器件(RTD)提供激励和信号调理功能， 适合1 kW 铂RTD (PRTD) ，可对极宽范围的温度进行测量。 它还能轻松与100W 接口。 借助远程、低成本薄膜PRTD，ADT70能够测量-50°C至+500°C范围内的温度。而采用高性能铂元件时，温度变化可扩展至1000°C。ADT70和PRTD系统在-200°C至+1000°C温度范围内的精度很大程度上取决于PRTD的质量。 通常，ADT70在传感器温度范围内的误差仅为±1°C，且可在单校准点上将误差调整至零。
