Operating Temperature Range | Sensing Element | Ice Point Resistance & Accuracy |
---|---|---|
-200°C to +232°C (-320°F to +450°F) with permissible exposure to 260°C (500°F) for short periods clamped. |
International grade platinum a = 0.00385Ω/Ω/°C nominal (IEC 751) | 100Ω resistance at 0°C 22810-1: ±0.50 ohms 0.50% of temperature 22810-2: ±0.22 ohms 0.25% of temperature |
Time Response | Long Term Stability | Self-Heating |
<0.2 seconds on metal surfaces | Less than 0.2°C drift per year at rated service temperature with proper mounting | The bare sensor will rise less than 1°C while dissipating an I2R power of 15 mW on metal surfaces |
Insulation Resistance | Lead Wire | Mounting |
Insulation resistance between outer sensor insulation clamped between two metal plates and the common lead wire is: 50 Megaohm (MΩ) minimum with 50 VDC applied to a dry sensor at room temperature (ASTM-E-644) | #26 AWG stranded nickel-plated copper conductors. 22810: PFA Teflon® insulated 3 or 4 conductor ribbon cable. 22830: PFA Teflon® insulated individual 3 or 4 conductors, PFA Teflon® overjacket. |
Will conform to surfaces with radii down to 3/8 inch transverse to the element winding and 1.5 inch longitudinal to the winding. CAUTION: Only bend transverse to grid axis. |
