Abstract:
1. A high temperature measurement probe configured to measure hot fluid, the high temperature measurement probe comprising: an elongate probe body having a measuring head which in use is located in a hot fluid flow, and a thermocouple extending along the interior of the probe body to terminate at a temperature-sensing thermocouple junction inside the measuring head; wherein: the probe body has internal passages configured to circulate a coolant fluid therein, the measuring head includes a channel that has one end forming an inlet for receiving hot fluid from the hot fluid flow and another end forming an outlet for discharging the hot fluid received at the inlet, and a section of the channel is disposed between the inlet and the outlet and extending along the length direction of the probe body, the thermocouple is configured to run along the section of the channel such that the thermocouple junction is proximate to an upstream end of the section, and is closer to the upstream end of the section than a downstream end of the section, the channel includes a first dogleg disposed at the upstream end of the section of the channel that is configured to turn the channel into the section, the channel includes at least one additional dogleg at the downstream end of the channel that is configured to turn the channel out of the section, and the first dogleg and the at least one additional dogleg are arranged such that the inlet and the outlet are located apart in the longitudinal direction of the probe body.
