Description
ABB PFTL101B 20.0KN 3BSE004203R1 is an ideal for application with low tension, heavy rolls and high running speeds, which are often found in the metallurgical industry.
ABB horizontal pillow tensiometer heads are available in three sizes: Standard PFTL 101A/B, which is commonly used in conventional metal handling lines. The indenter is suitable for applications with heavy rolls, wide tension ranges and high operating speeds.
PFTL 101AE/BE is recommended for strip tension measurement applications with emulsion in cold rolling, annealing and zinc plating lines. The PFTL 101AE/BE indenter uses a fixed connection cable and is protected to IP 66 for accurate and reliable long-term operation in emulsion applications. All ABB tensiometer indenters are calibrated at delivery.
The acid proof PFTL 101AER/BER indenter is designed for pickling lines and is rated IP 66/67.
PFTL101B 20.0KN 3BSE0042003R1 ABB’s Millmate strip tension measuring system indenter is based on the famous Pressductor® magnetic effect, patented in 1954, according to which the magnetic properties of steel are affected by mechanical forces.
There are four holes in the sensor. PFTL101B 20.0KN 3BSE0042003R1 Two coils perpendicular to each other are wound together through these holes. One coil is applied alternating current and the other coil acts as the measuring coil. Since the two coils are perpendicular to each other, there is no magnetic coupling between them as long as there is no load on the sensor.
If there is a load PFTL101B 20.0KN 3BSE0042003R1 on the sensor, the magnetic field characteristics will change. The magnetic permeability of the steel will decrease in the direction of the force and increase in the vertical direction. This results in a change in the symmetry of the magnetic flux, and part of the magnetic flux will induce induced voltage in the secondary side coil. The induced voltage is proportional to the load.
ABB’s unique piezomagnetic ® technology makes the Mini series of pillow indenters exceptionally strong, allowing them to withstand a wide variety of work strips
a piece.
