  Performance Specifications
   

Operating Temperature Range
The useful range of operation
for Model 22810 is:
–200°C to +232°C
(–320°F to +450°F)
with permissible exposure to 260°C (500°F) for short periods clamped.

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

Accuracy
Standard (22810-1)
±0.50 ohms 0.50% of temperature
Optional (22810-2)
±0.22 ohms 0.25% of temperature

Stability
The sensor will have less than
0.2°C drift per year at rated service temperature with proper mounting.

Time Response
<200 milliseconds lag on metal surfaces.

 

Self-Heating
The bare sensor will rise less than 1°C while dissipating an I2R power of 15 milliwatts on metal surfaces.

Lead Wire
#26 AWG stranded
nickel-plated copper conductors,
PFA Teflon® insulated
3 or 4 conductor ribbon cable.

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)

Mounting
Will conform to surfaces with radii
down to 3/8 inch transverse to the
element winding and 1 1/2 inch longitudinal to the winding.

Caution
Only bend transverse to grid axis.
Refer to AN-S (PN 22810) for
further information.
