Wide Operating
Temperature Range

–200°C to +232°C (–320°F to +450°F)
continuous as mounted.
260°C (500°F) short term clamped.

Sensing Element
International grade thin film platinum
a = 0.00385 Ω/Ω/°C or
Industrial grade thin film platinum
a = 0.00375 Ω/Ω/°C

Ice Point Resistance
100±0.12Ω or 1000±1.2Ω;
Class B (±0.12%)

Interchangeability
±0.3°C or 0.6% of temperature IEC 751 Class B above –50°C

Long Term Stability
Less than 0.05°C drift per 5 years
above –50°C

Time Constant
Less than 1/2 second
for the sensor to reach 63.2%
of a change in temperature

   

Self-Heating
The bare sensor will rise less than 1°C while dissipating 25 milliwatts mounted.

Insulation Resistance
The insulation resistance
between the outer metal faces
and the common leadwires is:
50 megohms minimum
with 50 Volts DC applied.

Maximum Current
100Ω=5mA, 1000Ω=2mA
for limited self heating

Recommended Current
1mA

Body Materials
Stainless Steel and flexible
polyimide fiber insulation

Lead Materials
Stranded copper cable
insulated as follows:

22 AWG tin-plated, (2-wire) FEP Teflon® over each twisted black/red, FEP overall.
24 AWG tin-plated, (3-wire) FEP Teflon® over each twisted white/2 red, FEP overall
26 AWG nickel-plated, PFA Teflon®, 2 white, 2 white/brown, or 2 white/2 red fused parallel

Teflon® is a registered trademark
of the DuPont Corporation.
