for indiacation of turbine(china) bearing temperature what
type of sensor will be used(i.e. rtd or thermocouple or
themister ) ? why it is ? i need clear explanation ?
Answer Posted / amsal
we use RTDs to measure the bearing temp of turbine because maximum temperature of turbine bearing reaches 120 C. and RTDs are better to measure that low range of temperature than a thermocouple. not due to vibration. But in GT V94.2 siemens we are using T/Cs instead of RTDs and its bearing temperature protection is 120C.
