Measuring principle
SB-TT Smart Temperature transmitter measures high precision process temperature using thermocouples or RTD sensors in 2, 3 or 4 wire configuration:

SB-TT measures microvolt changes by thermocouples and as result calculates temperature using ITS-90 standard Equations.
SB-TT measures resistance changes in RTD and as a result calculates temperature using ITS-90 standard Equations.
SB-TT uses High Precision 24 Bit A/D converters to measure microvolt signals from the sensor. It’s Heart of the outstanding Performance.
