The planar heater is classified as follows, according to the "feeding method" and the "heating element shape".
|Series Connection||The electrodes are connected by a single wire.|
|Parallel Connection||A plurality of heating elements are connected in parallel between the two electrodes.|
|Series Connection Type||Heated electric wire typified by Nichrome wire is processed into a planar shape.|
|Surface Heather||A type in which the conductor is uniformly fixed on cloth or film, and the entire surface is uniformly heated.|
|SENMEN Heater||Linear heating elements are densely arranged in a planar manner, generating heat without temperature unevenness, like the surface heater, but with the safety of the line heater.|
|Conductive Thread||It is a thread through which electricity can pass due to the conductive coating specially formulated into fibers.|
|Heater Structure||The electrode wires are arranged on both sides, with resistors connected in parallel. This structure allows a constant even temperature throughout that will not be affected by the cutting size, even just above the heater.|
|Cross Section of Heating Section||It is interlaced using insulation for warp thread and conductive yarn for weft thread.|
|Laminated MaterialVinyl Chloride"||Sufficient insulation performance in indoor use. (The photo shows after the heater has been cut and the lead wires attached. The insulation patch (PVC + PET) has been thermally welded.)|
SENMEN heater is one of a kind in the world, with a unique structure not found in other heaters.
Not only does it provide uniform heat generation without temperature unevenness, the calorific value is constant even if the dimension in the longitudinal direction changes. "
|Even if the length of the line heater changes or the output changes, the generated temperature remains constant.|
|With series electrode heaters…When the length of the heater changes, the output power is affected, which in turn affects the heat generation capacity.|
|With parallel electrode line heaters…The length of the line surface heater of a parallel electrode can be changed without changing the electrode width, therefore not affecting the heat generation. This allows the length to be adjusted freely.|
When the change in design occurs, the desired output setting can be easily adjusted by changing the weaving density of the conductive yarn.With surface heaters…When the design changes occur, it is difficult to obtain the desired heat generation levels as coating thickness and conductivity must be changed. Often thickness variations and uneven heat generation will occur.With the SENMEN Heater…When design changes occur, the output can be freely adjusted simply by changing the weaving density of the conductive yarn.
Since each wire of the electrode wire band is short-circuit bound with patented electrodes, the total capacity of each wire becomes "the capacity of the electrode wire band" allowing larger electric capacities. This structure allows for very long product lengths.
Please observe the following matters when designing the line surface heating element and processing the product.
Control the heater surface temperature so that it is below 80 ℃Control the heater surface temperature so that it is below 80 ℃.
If it gets higher than this temperature, the heater body may be thermally deformed.Once thermal deformation occurs, it does not return to its original form.
No SuperpositionHeating parts of the heater can not be overlapped.Abnormal heat will be generated in the overlapping areas, causing heat to escape abnormally causing damage to the heater.
Lifespan of ProductNot limited to just SENMEN heaters, but all heaters have lifetime limits. Please be aware that the heater is a consumable product. The lifespan will be greatly influenced by the design and use of the product. In general, the lower the watt density (output ÷ effective heating area), the longer the service life. Also, it is important to inspect the heater throughout its lifespan, checking for abnormal heat generation due to wire fuses, disconnections, perforations, or deterioration to safely ensure the reliability of your product.

"The standard products are all PVC shells.The heat generation capacity Δt is determined by the output per 1 cm 2 and the watt density The heat generation capacity Δt is about 15 ° C to 40 ° C.Heater surface temperature = ambient temperature + heat generation capacity + α (depending on heat radiation condition).It is necessary to control so that the heater surface does not exceed 80 ℃.
