Model Number Sensing Element Accuracy Max Temperature Price
SRTD-1 100.00 ±0.50 Ω at 0°C ±0.50% of temperature reading 260°C continuous $155
SRTD-2 100.00 ±0.22 Ω at 0°C ±0.25% of temperature reading 260°C continuous 170
Selected Specifications: 100.00 Ω at 0°C, temp coefficient = 0.00385 Ω/Ω/°C. Stability: <0.2°C drift per year at rated service and proper mounting.
Response time: 70 ms (63.2% response) in water flowing at 3' per second. Self heating: bare sensor will rise less than 1°C while dissipating 3 mW
in still air. Insulation resistance: 50 M Ω minimum at 50 Vdc (dry conditions at room temperature). Minimum bend radius: 9.5 mm (3⁄8") transverse to
element, 38.1 mm (11⁄2") longitudinal to winding.
