The KN series ceramic wire-wound platinum resistance temperature detector (PRTD) is designed for general applications requiring temperature stability. Its construction features a platinum coil hermetically sealed within a high-purity alumina ceramic body, with shear-resistant lead wires that ensure reliable connections to extension wires and cables. The measurement point is located 8mm from the end of the sensor body. The measuring current is 1mA, and tolerance classes comply with IEC 60751:2008; other standards and tighter tolerances are available upon request. The series offers excellent long-term temperature stability, with options including platinum-gold alloy, alternative temperature coefficients (3916 ppm/K — legacy JIS standard), and palladium-gold alloy lead wires. The assembled insulation resistance exceeds 100 MΩ at 25°C.

• Temperature range: W0.3 (Class B) -196°C to +660°C; W0.15 (Class A) -100°C to +450°C; W0.1 (1/3 Class B) -100°C to +350°C
• Response time: water flow (v = 0.4m/s) t0.5 = 0.2s, t0.9 = 0.3s; air flow (v = 3m/s) t0.5 = 3.0s, t0.9 = 9.0s
• Self-heating: 0.14 K/mW at 0°C

• Insulation resistance: >100 MΩ at 25°C after assembly
• Temperature stability: excellent long-term stability
• Options: platinum alloy, alternative temperature coefficient (3916 ppm/K - legacy JIS), palladium-gold alloy leads
