Introduction

The NF02 has been designed for studies of the energy balance of industrial installations, in particular steel and iron walls.
The main component, the actual sensor, is incorporated in a fully stainless steel needle.
This sensor can withstand temperatures up to 700 degrees C.
The extension cable is made of metal (first part) and Teflon (second part).
Sensor output consists of a heat flux signal (microvolt analog signal) and type K thermocouple. NF sensors can be manufactured in such a way that they are fully exchangeable, which is easy for servicing. Also the exact depth of insertion is not critical, which saves installation time.

Options

  • Alternative designs: Hukseflux is specialised in heat flux sensor design. For different applications special models can be constructed.
  • NF02 can be made in different diameters and lengths. See model NF01 for larger versions of NF01. Extended temperature to 700 degrees C. (no spring)

Suggested Use

  • Studies of energy balance of industrial processes
