Schelt Technology

Similar to the MF-180 but waterproof and durabledesign for soil heat flow measurement. All sensors areextremely flat, which is a big advantage consideringthe minimum interference with the conditions of thetesting area the thermal dynamics. The low outputVoltage of the heat flow sensor can be easilyconverted to a 4-20mA current or higher Voltage usingthe MS-4..20mA converter. The mV/mA converter canbe pre-programmed and optimized within the operatingrange compatible with common measurementequipment.

The HF-30S is a large area (300 x 300mm) fthin foilheat flow sensor. Due to its large sizes it gives properlyaveraged thermal conductivity results for large areaswithout the potential risk of measuring local hot spoteffects or thermal bridges.The low output Voltage of the heat flow sensor can beeasily converted to a 4-20mA current or higher Voltageusing the MS-4..20mA converter. The mV/mAconverter can be pre-programmed and optimizedwithin the operating range compatible with commonmeasurement equipment.

The MF-180 is a thin, sensitive, heat flux sensor. Smalland easy to handle, the MF-180 is easy to attach toand detach from a range of surfaces. It can measuremedium to low heat flux values, and is suitable for arange of applications; with a measurement range from-30 ֯C to 120 ֯C.A heat flux sensor is a thermopile, an electronic devicethat translates thermal energy into electrical voltageproportional to the temperature gradient across itsthermocouples' hot and cold junctions. To generate ahigh enough measurable voltage, heat flux sensors areequipped with multiple thermocouple junctionsconnected in series, distributed over the area of thesensor.EKO Instruments offers a selection of thin substrateheat-flux sensors, in a range of different sizes andthicknesses; an ideal option for research andengineering applications as well as manufacturingcontrol and monitoring processes.
