Performance Specifications

   
 

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. TM-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.
