Radiation heat flux sensor

Our company is a manufacturer and supports customization

GTT/STT series heat flow sensor/radiation heat flow sensor

Heat flow sensors/radiation heat flow sensors are used in ground and flight aviation tests, heat transfer research, flammability testing heat flow standards, fire testing, material development, and kiln development.

Sensor Description

structure

Accurate, sturdy, and reliable sensors.

Oxygen free copper body ensures long lifespan and signal stability of the sensor.

Equipped with flanges for easy installation. Attachment

Optional configurations: including four installation configurations, detachable windows, water cooling, and conduction cooling. When the working temperature exceeds 200 ° C, water cooling should be chosen.

Window attachments (optional window materials such as sapphire, quartz, zinc sulfide, zinc selenide, etc.), measure radiation heat flux (total radiation, infrared radiation).

The standard installation configuration is shown in the figure. Including smooth surfaces with flanges; Threaded surface with flange; Smooth surface without flanges; Threaded surface, without flange
