The task is to calibrate a Resistance Temperature Device [RTD]. The RTD forms one leg of a Wheatstone bridge, and the RTD has the following parameters: Coefficient of resistance a = 0.00392+0.00005 C¹ (95%) Uncertainty in R: UR =±0.001 (95%) When the bridge is balanced with T= 0°C: R₂ =100.000 2 and when balanced at 100°C: R. 139.200 Determine RRTD at 0°C and at 100°C; determine the design stage uncertainty when for some temperature R₁ = 300 2 and u₁ = ±1.0x10 / °C (95%). Equation for RTD: RRID=R₁[1+a T-To)] Resistances in the Wheatstone Bridge: E₁ RTD Re variable R₂ = 100 R₂ = 1000 The task is to calibrate a Resistance Temperature Device [RTD].
