Water-cooled probes

Definition

Water-cooled probes are specialized instruments designed to monitor combustion processes by maintaining a lower temperature at the sensing elements through the circulation of water. This cooling mechanism is crucial in high-temperature environments, as it helps prevent damage to the sensors and allows for accurate measurement of combustion gases without interference from thermal effects. They are an essential component of in-situ sensors for efficient and reliable combustion monitoring.
