Monitors for pressurized systems

A sensor system, comprising:

• a first temperature sensor configured to generate a first sensing signal representing a first temperature of a first system component at a first location, the first temperature sensor including a temperature sensing element within a probe tip configured to engage with the first system component at the first location;
• a power source configured to convert thermal energy received from the first location to electrical energy;
• sensor circuitry configured to generate sensor data based on the first sensing signal using the electrical energy from the power source, the sensor circuitry being characterized by a thermal rating;
• one or more heat dissipation components;
• a first mounting component;
• and
• one or more thermal isolation components configured to thermally isolate the probe tip from the power source and from the first mounting component;
• wherein at least the first temperature sensor, the power source, the sensor circuitry, the one or more heat dissipation components, and the first mounting component are combined in a first integrated assembly configured for mounting on the first system component at the first location using the first mounting component, and wherein the first integrated assembly is constructed such that a second temperature of the sensor circuitry remains within the thermal rating over an expected range of the first temperature.
