Heat flux sensor heating element HTR02

flatplate

Overview
HTR02 series heaters are thin-film foil heaters designed for quick, objective functionality and performance checks of heat flux sensors, such as the FHF05 series. Featuring a cable with a 4-wire connection, a well-characterized traceable surface area, and a certified electrical resistance, they allow users to verify sensor sensitivity and stability before and after experiments using standard laboratory accessories. HTR02 heaters are available in two standard sizes—50 x 50 mm and 85 x 85 mm—and can be utilized either for sensor performance validation stacks or as general-purpose heating elements.

Key features

• In-situ sensor verification: Enables simple, objective performance checks and stability validation of foil heat flux sensors before and after use.
• Full FHF05 compatibility: Sized to match and test all models across the FHF05 series heat flux sensors.
• Traceable specifications: Delivered with a product certificate detailing traceable surface area (in m²) and individual heater electrical resistance (in Ohm).
• 4-wire connection: Equipped with a 4-wire (2 x 2 wires) cable configuration to permit precise voltage and resistance measurements directly across the heater.
• Ultra-thin profile: Thin-film foil construction with a thickness of only 0.1 x 10⁻³ m ensures minimal disturbance to thermal pathways.
• Broad thermal range: Rated for continuous operation across a temperature range of -40 to +150 °C.
• Dual-purpose use: Functions both as a verification tool for sensor sensitivity checks and as an accurate general-purpose foil heating element.

Applications
