Platinum Rtd Temperature Sensor, Temperature Range: -40 to 450 deg C

Duplex RTD (Resistance Temperature Detector) with a transition temperature sensor typically consists of two RTD elements within a single probe, allowing for redundant or simultaneous temperature measurements. The "transition" aspect likely refers to a transition joint where the sensor wires connect to a different type of wiring for connection to a measuring device. Specifications for these sensors vary, but generally include temperature range, accuracy, sensor type (e.g., Pt100), probe dimensions, and wiring configuration (e.g., 3-wire or 6-wire). Platinum RTDs, commonly used in these sensors, can handle a wide range, often from -200°C to 600°C or higher, but the specific range depends on the RTD element and the transition joint material.
