Rosemount™ 214C RTD Temperature Sensor
The Rosemount 214C RTD Temperature Sensor is a Pt-100, single or dual element resistant temperature detector (RTD) that covers a wide range of temperatures, from -321 to 1112°F (-196 to 600°C).
An exceptional solution, this sensor has a thin-film and wire-wound design for application flexibility. With many calibration options, including Class A or B sensor accuracy, this sensor also offers Callendar-Van Dusen constants for transmitter-sensor matching to provide the highest level of accuracy.
