Temperature Sensors HEL-775 Series

PLATINUM RTDs

FUNCTIONAL BEHAVIOR

ACCURACYVS TEMPERATURE

R_T= R₀(1+AT+BT²-100CT³+CT⁴)

RT = Resistance (W) at temperature T (°C)

R₀= Resistance (W) at 0°C

T = Temperature in °C

EL-700 platinum RTDs are available in two base

resistance trim tolerances: ±0.2% or ±0.1%. The

corresponding resistance interchangeability and tempera-

ture accuracy for these tolerances are:

A = a + a d

B = -a d
