Pt 100 foil element


Pt100 Foil element
Art.nr: 263601 [Larger]

Technical data
Temperature range
-200...+200°C.
Response time
T0,5 = 1 sec on surface.
Measurement uncertainty
According to DIN IEC-751 class A:
0,15 + 0,002|t|* °C
*|t| = the absolute value of the temperature in degree Celsius.
General
Pt 100, 11x30x0,13mm
• Small mass
• Fast response


Foil element are used for high accuracy surface and air temperature measurements. Due to the sensors low heat capacity (big surface, low mass) the measured objects temperature is little affected and the response time is fast. Foil elements give also fast response time.

The resistance of a Pt100 sensor at -200 - 0°C is calculated according to this formula:
Rt=R0(1+3,9083x10-3t - 5,775x10-7t2 - 4,183x10-12(t-100)t3)

The resistance of a PT100 sensor at 0 - 850°C is calculated according to this formula:
Rt=R0(1+3,9083x10-3t - 5,775x10-7t2)

R0, resistance at 0°C. (100 Ohm) Rt, resistance (Ohm) at the temperature t. (°C)
