Working principles, advantages and disadvantages of the servo and magnetic surface tension meters

January 27, 2014-USA-Currently, according to the high or low of the performance, the surface tension measurement could be mainly divided into the servo surface tension meter, electronic surface tension meter, magnetic surface tension meter and the mechanical tension device. Today, the engineer from USA KINO (www.surface-tension.org )will mainly introduce with people the work principle, advantages and disadvantages of the servo and magnetic surface tension meter. ¡¡ Servo surface tension device

The working principle of the servo surface tension device should be mainly concluded into below information. Through the angular displacement of the tension arm, the angle sensor will convert the angle changing into electrical pulses which could drive the servo motor running automatically. The tension switching is responsive without any volatility. This kind of device is adapted to the manufacturing of high-precision products.

The engineer from website surface-tension.org said that the advantage of this kind of device should be that this device has already displaced the traditional passive way. The tension testing value of this device is particularly stable and minimum tension could be up to 1g. The disadvantage should be the influence of the motor characteristics. The engineer from surface-tension.org recommended uses this device in line speed of 6m / s or less.

Magnetic surface tension device

The Magnetic contact angle goniometer generated damping by the magnetic torque which not produces any kinds of mechanical friction. So, this kind of surface tension device could generate long term and stable tension force. The precision of the testing value of this device can be effectively guaranteed. This product could totally meet with the general accuracy product. It is very cost effective.

However, the engineer from website surface-tension.org has said that there are also some disadvantages of this device. As the structural constraints of surface tension itself, the tension device can only be set and adjusted from small to large tension force. If people want to tune into the tension from small to high tension, the device must be kept at stopped state and then people could adjust it to the related force they want.

All of information above is the basically description of the working principle, advantages and disadvantages of the Servo and magnetic surface tension device. However, there are also other types of tension devices such as mechanical tension device and electronic surface tension device. Each type of device has their unique features.
