Notes: For internal temperature sensor, temperature (°C) = Y1U + Y2U2 + Y3U3, U0 = temperature signal period (µs) at 25°C, U = temperature signal period – U0 (µs). For pressure transducer, pressure (psi) = C(1 – T02/T2)[1 – D(1 – T02/T2)], T = Pressure signal period (µs), U0 = temperature signal period (µs) at 25°C, C = C1 + C2U + C3U2, D = D1 + D2U, T0 = T1 + T2U + T3U2 + T4U3 + T5U4.
