Product Description:


yarn tension meter
1.portable,compact,mechanical tension measuring device.
2.dependence and accuracy.

1.Brief introduction of instrument:

Measuring apparatus this adopt accurate transmission device that develop newly,can

make the instrument in measurement steady accurate reading the necessary data fast.

this instrumental error values in positive and negative 1 Newton scope.

In the screen printing of network monitoring silk screen version of the manufacture and

use of the process Screen tension values may also be used for other needs Plane tension

measurement products.


1.Before using please put the tension meter on the glass and turn round the dial to make the pointer return to zero.

2.Flick the silk screen during measuring, the indication when the pointer stopped is the tension of the silk screen.

3.Tension meter is precision meter, fall and touch is forbidden, be careful during using.

4.Tension meter has been tested precisely when leave the factory, dismounting alone is

not allowed.

5. Can’t touch the bottom side contactor by hand, put the machine vertically without using.

6. The Newton indication is the indication of the tension’s contactor, the error is +0.5N.

7. The indication of the second circle is the measured value during measuring.


NR110 digital colorimeter electronic test instruments is under warranty for 12 months from the purchase

date. Customers must provide warranty card and valid proof of purchase.

Q:What is the meaning of the residual pressure in the fan equipment parameters?
The external pressure of the machine is the sum of the dynamic pressure and static pressure at the outlet of the fan. Usually, the static pressure is often neglected and the dynamic pressure is neglected. When the air volume is small, the effect of dynamic pressure is small. Such as fire exhaust fan) generally in accordance with the machine outside the pressure election.
Q:What is the difference between a volute fan and a centrifugal fan?
Commonly used is a volute centrifugal fan, so the name of the "volute" was omitted. The full name of the volute without a volute is a volute-free centrifugal fan, which is also known as a plug fan or a Plenum fan on different occasions.
Q:How to buy Reiter high-speed centrifugal fan?
The General large-scale fan widely used with the motor directly connected to the A, the large fan, and sometimes belt drive discomfort, and more to drive D, F drive. On the high temperature, dusty conditions, the transmission method should also consider the motor, bearing protection and cooling problems.
Q:What is the working principle of centrifugal fans?
It is generally not necessary to consider changes in the specific volume of the gas, i.e., treat the gas as an incompressible fluid.
Q:How to see the axial fan is good or bad?
Axial fans are mainly composed of fan impellers and housings. The structure is simple but the data is very high.
Q:Why the blower suddenly does not turn?
Check the above are normal circumstances, you can ask the relevant management personnel, the factory there is a phenomenon in the power flash.
Q:How does the material of the high temperature fan choose?
According to the use of the fan and the use of different conditions, in the choice of materials should take into account the media corrosion, the temperature of the medium, the amount of gas emissions, explosion-proof and the choice of materials, such as the economic requirements.
Q:How to distinguish the high, medium and low pressure of the fan?
N = 60-30 for the medium pressure fan; n = 30-5 for the high pressure fan, the specific speed is calculated by the calculation.
Q:Is the centrifugal fan plugging the air inlet motor?
However, the motor is still running at high speed, the corresponding mechanical loss and other losses, but still continue to consume, and block the air intake of this way to save the electricity is much greater.
Q:How to determine the direction of centrifugal fan?
When the impeller is clockwise rotation and fan outlet in the lower left to oblique above 45 degrees blowing gas, said the right 45 degrees
