MF-180M Heat flux sensor:

Similar to the MF-180 but waterproof and durable design for soil heat flow measurement. All sensors are extremely flat, which is a big advantage considering the minimum interference with the conditions of the testing area the thermal dynamics. The low output Voltage of the heat flow sensor can be easily converted to a 4-20mA current or higher Voltage using the MS-4..20mA converter. The mV/mA converter can be pre-programmed and optimized within the operating range compatible with common measurement equipment.

Due to a strong drive for energy saving nowadays, obtaining accurate information on the thermal insulation of facilities such as buildings, offices, factories, and houses has increased. The MF and HF-Series Heat Flow Sensors are designed to directly measure the heat radiation or heat transmission from walls, floor/ground, stock storage walls, and freezer walls, as well as to measure the heat flow rate underground, by embedding or attaching the Heat Flow Sensor to the measuring part.
The MF-180 and MF-180M are compact type heat flow sensors with high sensitivity. MF-180M is designed for outdoor use. HF-Series are thin types of heat flow sensors. Both HF-30S and HF-10S can be attached on a curved surface. By combining several heat flow sensors with an insulated box, a calorimeter device can be created.

A heat flux sensor is a thermocouple, an electronic device that translates thermal energy into an electrical voltage proportional to the temperature gradient across its thermocouples’ hot and cold junctions.

EKO Instruments offers a selection of thin substrate heat-flux sensors in a range of different sizes and thicknesses, an ideal option for research and engineering applications as well as manufacturing control and monitoring processes.

The MF-180M is tough enough to withstand constant outdoor exposure because it is made of epoxy resin and is based on a Teflon (PTFE) substrate with carbon fiber-reinforced plastic cladding. It’s tough, sensitive, and comes in the same small (4 x 2 cm2) size as the MF-180, making it suitable for a range of applications.
