MODEL 22810


Model 22810 is a polyimide insulated surface sensor designed to provide a practical method for measuring surface temperature. These sensors are small, flexible, and their low mass has minimal thermal effect on the material being measured. They are ideally suited for applications where the device can be permanently mounted using adhesives or other mechanical mounting methods.

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 (IEC751).
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 22800) for further information.
