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:Is the centrifugal fan plugging the air inlet motor?
If it is to take the energy saving way to block the air intake to save electricity, it would be better to directly change the centrifugal fan control mode is simple and convenient
Q:How to judge the fan left and right rotation?
The main structural components of the fan are impeller, housing, air inlet, bracket, motor, pulley, coupling, silencer, transmission (bearing) and so on.
Q:What is the critical speed of the fan?
More than this speed after the amplitude increases with the speed gradually reduced, and stable in a certain range, the rotor maximum amplitude of the rotor speed is called the critical speed
Q:How to distinguish between the fan coil around?
The fan coil is the ideal end of the central air-conditioning products, from the heat exchanger, water pipes, filters, fans, water tray, exhaust valve, bracket and other components, the working principle of the unit is constantly recycling room air
Q:What is the working principle of the suction blower?
The principle of suction can also fan example, the blade side of the compressed air, the back of the air density is reduced, the need to add air to restore the original balance
Q:What is the operation of centrifugal fans and axial fans?
Fan in the work, the air flow from the fan into the blade space, and then driven in the impeller on the next side with the impeller rotation; the other hand, under the action of inertia to improve energy, along the radial direction away from the impeller, the resulting centrifugal force to do work The fan is called a centrifugal fan
Q:What is the effect of the centrifugal fan on the wind pressure?
With the export of cross-sectional area continues to increase, air volume also increased, the pressure decreased.
Q:What is the meaning of the residual pressure in the fan equipment parameters?
The concept of external pressure is generally from the manufacturer sample sample provided by the machine outside the pressure is generally considered the unit itself after the pressure loss can provide the full pressure, the sample in addition to providing static pressure outside the machine, will provide outside the machine Residual pressure value, but rather the machine is not necessarily have static pressure
Q:Why should the safety valve be installed at the Roots blower exit?
Even if the fan outlet is completely blocked (in fact, start the centrifugal fan should be closed the outlet) will not cause damage to the fan.
Q:What is the principle of explosion-proof fan?
The use of anti-corrosion materials coated with epoxy paint from the motor using a special anti-corrosion motor for the transmission of corrosive gases. Explosion-proof axial fan (BT35-11 type), used to transport flammable and explosive gas
