One of the newest signal conditioning circuits addreses the needs of one of the oldest sensing technologies. Designed for K- and J-type thermocouples, Analog Devices’ AD8494, AD8495, AD8496 and AD8497 thermocouple amplifiers include cold junction compensation and a high gain accuracy precision amplifier. The integrated cold junction enables accurate measurements over a wide temperature range. […]

Designing with Thermistors
John R. Gyorki, Editorial Director Temperature sensor applications usually fall into one of three general categories; monitoring, control, or circuit compensation, and four sensor types; thermocouples, thermistors, resistance-temperature detectors (RTD), and semiconductor temperature sensors. When selecting a sensor, some key characteristics to consider include temperature range, accuracy, response time, minimal temperature effect on the measured […]
