93831-99 RTD Probe, 100 Ohm, ANSI 3-Blade Connector, 18" L, 3ft SS Braid Cable by Digi-Sense

Maximum error for probe assembly is ±1.1°C + 0.12% of reading below 300°F, ±0.35% of reading above 300°F. Alpha coefficient is 0.003850 Ω/Ω/°C (DIN IEC 751). Resistance at ice point (0°C) is 100 Ω.

Note: Time constant is the time required to reach 63.2% of the new reading. To determine how long it will take to reach 99% of the new reading multiply the time constant by five.

Note: The temperature range is for the probe tip only. The handle material may be affected if the probe is rated higher than the handle depending on exposure time, application, and handle material. ABS handles are rated to 220°F (104°C); PVC handles are rated to 200°F (93°C); Stainless Steel handles are rated at 450°F (232°C); Mini Connectors are rated to 392°F (200°C).

• Time Constant: 1-3 seconds or greater
• Custom designs or changes to this product are available upon request
