Thermal Sensors Gardon gauge water-cooled high heat flux sensor GG01 is a water-cooled sensor that measures heat flux. The Gardon gauge sensor is based on copper and copper alloys, and works at heat flux levels at which other sensors get toasted. Optionally GG01 can be equipped with a sapphire window; to measure radiative heat flux only, and not convective heat flux. GG01 has an on-board thermocouple type K and is available with various dedicated measurement ranges. Introduction GG01 measures heat flux in the range of (250 to 1000) x 103 W/m2. Equipped with a black absorber, heat flux sensors of this type are designed for measurement in an environment in which heat flux is dominated by radiation. Using an open detector, GG01 is also sensitive to convective heat flux. The GG01 Gardon gauge sensor, based on thermocouple materials, generates an output voltage proportional to the incoming irradiance. A type K thermocouple measures the body temperature. The sensor is water-cooled. Water cooling is usually supplied by tap water. Figure 1 GG01 Gardon gauge water-cooled high heat flux sensor. It works at heat flux levels at which other sensors get toasted. There are 3 versions of GG01; each with a different rated measurement range, sensitivity and response time. Irradiance ranges are (250, 500 and 1000) x 103 W/m2, for GG01-250, GG01-500 and GG01-1000 respectively. The body is equipped with a flange for easy mounting. GG01250 may be equipped with a sapphire window. See options. Gardon gauge technology GG01 is made using oxygen-free high thermal conductivity copper and thin foils of a coppernickel alloy. The sensor is called “Gardon gauge” after its inventor Robert Gardon. The benefit of this technology is that it can withstand very high heat fluxes. GG01 has several advantages: • • • • • withstands very high heat fluxes fast response time equipped with type K thermocouple to measure body temperature suitable for use in high vacuum safe storage with a practical protection cap Suggested use Figure 2 GG01 sensor in a high heat flux test cabinet. Each sensor is tested at its rated measurement range. GG01 is the sensor of choice for high heat flux measurements. Copyright by Hukseflux. Version 2007.
