PFTL301E-1.0KN 张力计是检验丝网印版质量的重要的检测仪器

张力计是一种用于测量张力的仪器，常见于航空、汽车、拖拉机、建筑等工业部门中测量钢索的张力（拉紧力）的场合。张力计有机械式和电子式两种，PFTL301E-1.0KN 可以测量丝网受到拉力作用时其内部与固定丝网接触体之间的相互牵引力大小。

张力计的测量单位用gf或者kgf表示，PFTL301E-1.0KN 可以通过张力计自身重量使丝网下沉的深度的数值（毫米）来计算，张力数值可从指示盘上直接得到，或者从控制盘上间接得到。

此外，张力计还有另一种用途，即土壤张力计，是一种观测土壤水张力的直读仪器。PFTL301E-1.0KN 利用负压计测定土壤水分，是从能量角度研究土壤水分运动的实用手段。土壤愈湿，对水的吸力就愈小；反之则大。当土壤湿度增大到所有空隙充满水时，土壤水张力将降为零。各种土壤的饱和含水率一致。各种土壤的饱和含水率，以重量含水率和容积含水率而言都不一致，但对土壤水张力而言却是一致的。

Tensiometer is an instrument used to measure tension, which is commonly used to measure the tension (tension) of steel cables in aviation, automobiles, tractors, construction and other industrial sectors. There are mechanical and electronic tensiometers, PFTL301E-1.0KN can measure the mutual traction force between the wire mesh and the fixed wire mesh contact when the wire mesh is subjected to tension.

The measurement unit of the tensiometer is expressed in gf or kgf, and the PFTL301E-1.0KN can be calculated by the value of the depth of the wire mesh sinking by the weight of the tensiometer itself (mm), and the tension value can be obtained directly from the indicator dial or indirectly from the control dial.

The tensiometer is an important testing instrument to test the quality of the screen printing plate, and it should be used to measure the tensiometer during or after the stretching of the net.

In addition, the tensiometer has another use, that is, the soil tensiometer, which is a direct reading instrument for observing the tension of soil water. PFTL301E-1.0KN using negative pressure gauge to measure soil water is a practical means to study soil water movement from the perspective of energy. The wetter the soil, the less it attracts water. The opposite is greater. When soil moisture increases to the point where all voids are filled with water, soil water tension will drop to zero. The saturated water content of all soils is the same. The saturated moisture content of all soils is not consistent in terms of weight moisture content and volumetric moisture content, but it is consistent in terms of soil water tension.
