_ Performance Specifications

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

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

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


The bare sensor will rise less than 1°C while dissipating power of 25mW

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)

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
