Ceramic Wirewound

The following sensor is only available from Heraeus Nexensos USA

Ceramic Wire wound Platinum RTD (Pt RTD) Elements are characterized by extremely high stability, high-temperature capability, and high accuracy over a wide temperature range. We offer a variety of ceramic wire wounds (both single and dual RTDs) in a wide choice of resistance values (Pt100, Pt200, Pt500 and different temperature coefficients (TC3850, TC3916). These Positive Temperature Coefficient (PTC) sensors are designed for applications requiring tolerances extended over wide temperature ranges. Ceramic wirewound RTD elements are also referred to as CWW or platinum bulb.
