Operating Temperature Range
–270°C to +260°C (–452°F to +500°F)
Continuous as mounted (300°C short term)

Sensing Element
The standard sensing element is platinum wire with a resistance of 100 Ω at 0°C with a temperature coefficient of 0.00385Ω/Ω/°C nominal (IEC751) or 0.00391Ω/Ω/°C reference grade

Accuracy
Standard (-1, -3) ± 0.50 Ω or 0.50% of temperature, whichever is greater
Optional (-2, -4) ± 0.22 Ω or 0.25% of temperature, whichever is greater

Time Response
<200 milliseconds lag on metal surfaces

Stability
The sensor will have less than 0.02°C drift per year at rated service temperature with proper mounting

Self-Heating
The bare sensor will rise less than 1°C while dissipating power of 25mW
(ASTM-E-644)

Insulation Resistance
The insulation resistance between outer sensor insulation clamped between two metal plates and the common lead wire is 50 megohms minimum with 50 VDC applied to a dry sensor at room temperature (ASTM-E-644)

Mounting
Will conform to 2 inch minimum diameter (see ordering data)

Body Material
Stainless steel and flexible polyimide fiber insulation

Lead Wire
#26 AWG stranded nickel-plated copper conductors, PFA Teflon® insulated 3 or 4 conductor ribbon cable
