  Performance Specifications
   

Operating Temperature Range
For S [standard]:
-200°C to 260°C (-320°F to 500°F),
For H [high]:
0°C to 480°C (32°F to 900°F)

Sensing Element
The standard sensing element is platinum with a resistance of 100Ω at 0°C
with a temperature coefficient of resistance 0.00385 Ω/Ω/°C nominal
(IEC 751).

Interchangeability
±0.1Ω (±0.25°C)
or 0.4% of temperature,
whichever is greater.

Stability
The sensor will have less than 0.05°C drift per year at rated service temperature with proper mounting.

Time Response
8 seconds for the sensor to reach 63.2% of a step change in temperature
in water flowing at 3 feet per second transverse to the sensor. (ASTM-E-644)

Self-Heating
The bare sensor will rise less than 1°C while dissipating power of 35 milliwatts
in still air. (ASTM-E-644)

Insulation Resistance:
The insulation resistance
between outer sensor housing
and the common leadwires is:
50 megohms with 50 VDC
applied to a dry sensor
at room temperature.
(ASTM-E-644)

Lead Wire
S: #22 AWG stranded
nickel plated copper
TFE Teflon® insulated,
3-wire configuration.
H: #22 AWG stranded
nickel plated copper
fiberglass insulated,
3-wire configuration.

Mounting
Sensors can be bolted, clamped or welded into place.
