Description

The HFS series has been discontinued. contact our Temprature Engineering department.

Each HFS series Heat Flux Sensor functions as a self-generating thermopile transducer. It requires no special wiring, reference junctions or signal conditioning. A readout is accomplished by connecting a sensor to any direct reading dc microvoltmeter or recorder. The HFS series sensor is designed for precise measurement of heat loss or gain on any surface. It can be mounted on flat or curved surfaces and employs butt-bonded junctions with a very low thermal profile for efficient reading. The HFSs utilize a multi-junction thermopile construction and is available in two different sensitivity ranges. The carrier is a polyimide film which is bonded using a PFA lamination process.

The sensor also has an integral thermocouple for discrete temperature measurement needed to describe the heat flux.
