LS 100TD Tension sensor for automatic tension controller and magnetic powder brake clutch

Principle:

Tension sensor is an instrument used to measure the tension value of coils in the process of tension control. Taiwan kaide sensor and amplifier. The strain gauge type is tension strain gauge and compression strain gauge, which are connected together in accordance with the mode of electric bridge. When subjected to external pressure, the resistance value of the strain gauge also changes, and the change value is proportional to the magnitude of the tension. Micro displacement type is through the external force applied load, so that the spring displacement, and then through the differential transformer detected tension, because the spring displacement is very small, about 200 m, so called micro displacement type tension detector. Additional, go up to be divided again by exterior structure: axial table type, wear shaft type, cantilever type.

Technical parameters:

Connection methods:

A tension sensor with a compression block connection measures the tension of the coil through a stationary shaft and a moving shaft. A tension sensor is mounted on each end of the frame, and the idler roller is supported between the two tension sensors.The clamp-shell connection allows idler rollers to be easily installed when tension sensors are mounted on both ends of the rack. This connection can adjust the non-coincidence between the rack and idler rollers after thermal expansion during machine operation. This unique design can also be applied to the static axis and the motion axis.

Within the roll type

The in-roll connection is directly embedded into the two ends of the idler roller. The two ends of the rack are equipped with a tension sensor, and the idler roller is installed between the two tension sensors. This in-roll connection USES spherical bearings to smooth the adjustment of the idler roll rotation and misalignment between the frame. This connection eliminates the need for idler rollers for shaft and bearing, thus reducing the cost of the tension detection system.

Line wheel

This type of thread wheel USES simple ply applications for a variety of materials. When connected to both ends of the rack or bracket, the tension sensor tests the tension through the nickel plated aluminum tension sensor strand.
