Screen Tensiometer
1.The tension meter has been calibrated to zero before leaving the factory, and users should not
adjust it by themselves.
2.Reading method: The reading of the second rotation of the tensiometer pointer is accurate
(and the mesh next to the tension meter should be lightly slid).

The data in the table was tested based on Swiss medium and thick yarn, specifically tension is
related to the quality of the mesh stretching machine, with good quality mesh stretching machine,
the mesh yarn can reach the highest tension and not broken. However, if the mesh yarn is
beyond the maximum withstand tension, it's easily broken. Please kindly refer to the below data:

OUR PRODUCT
Tensiometer is used to measure the tension of the stretched mesh and is an indispensable
tension measurer in the stretched net process.
Selecting a high-precision tensioner is the key to plate making and overprinting.
The tensiometer is easy to operate and easy to read. The error is small and the accuracy is high.
The tensiometer is an instrument that measures the amount of mutual traction between the
inside of the wire mesh and the fixed wire mesh contact when the wire mesh is under tension.
The unit for measuring tension is expressed in Newtons/cm.
Tension can also be expressed in relative values.
The centimeter tensiometer is a kind of relative tension, which is calculated by the value of the
depth of the tensiometer to sink the wire mesh (mm). The tension value can be obtained directly
from the indicator panel or indirectly from the control panel. get. Tensiometer is an important
testing instrument to check the quality of the screen printing plate. In order to ensure the tension
required by the plate making, the tension meter should be used during or after the stretching.
Reading display mode: the first reading of the tensiometer reading pointer is incorrect, the second
reading of the tensiometer rotation is normal, and the net yarn beside the tensiometer must be shaken.
Feature:
1.This product is a portable, compact, mechanical tension measuring device for accurate and
consistent measurement of all screen printing fabrics in Newtons per centimeter (N/cm).
2.It consists of a shock-resistant measuring base with a precision mechanical dial indicator.
it works on the principle of force-deflection; the unique design of the meters 3-point measuring
base permits accurate measurement on the screen (polyester, nylon, or wire), independent of the
screen frame or stretching device.
3.Substantial improvement in tension measuring methods as compared to touch control, gauging by
percentage of fabric elongation, and air pressure values.
4.Accurate tension measurements will improve registration and reduce rejects, resulting in increased
productivity.
5. Reproducible and uniform tension measurement, screen after screen.
Tensiometer Accessories
Note: The tension of the mesh is N/cm, which means how much tension the mesh has in the
width per cm (usually expressed in N-Newton or Kg-kg, 1 kg = 9.8 Newton).
So Newton shows that the tension meter has The actual number of tensions.
Measurement Methods And Steps
Zero Adjustment
Remove the tensiometer from the box, place it on the glass calibration block, and then
turn the fixing screw counterclockwise to allow the zeroing dial to rotate. Rotate the zero
plate to zero and confirm.
Measuring
Flip the mesh and place it horizontally (PCB contact side up) place the tensiometer at the four
corners and center of the screen, check the tension value at each point and record the
minimum value. Check whether the screen tension test value is within the allowable range,
if the measured value does not meet the standard, please feedback to the engineer for
processing.
After the measurement, put the tensiometer back into the box in time,
and then put it back on the knife holder.
