Strip tension, is one of the key parameters for achieving high precision strip thickness control in the cold rolling process. To achieve the highest possible accuracy, a strip tension meter is the best and most reliable tool. Accurate strip tension measurement is key to stabilising the strip tension within the desired range during acceleration and deceleration.
The Millmate Strip Tension Measurement System consists of a Millmate 400 controller, a junction box, and two indenters of the appropriate range. The indenter can be used to measure force in two different directions, one vertical and the other horizontal, depending on the application.
ABB's equipment is easy to install and operate, and ABB's extensive experience in cold rolling gives us a wealth of application expertise in this particular area.The advantages of Pressductor technology include high measurement accuracy and high overload capacity in all force directions. All presses are extremely resistant to overloads, vibrations and shocks as well as being dust and corrosion resistant. All pillow-type indenters are made of highly resistant stainless steel and have hermetically sealed internal components. Press heads for rolling mills are used in extremely harsh environments such as cold rolling mills and galvanising and pickling lines.

Indenter:
ABB's strip tension measurement system indenter is available in four versions, three for vertical force measurement and one for horizontal force measurement.
Available in a variety of sizes, including a wide range of ranges, the indenter provides an output signal proportional to the measured force FR. ABB's indenters
feature rugged construction and excellent protection ratings, including an internal Pressductor force sensor for use in harsh rolling environments. The press head
has a robust construction and an excellent level of protection, with an internal Pressductor force sensor for use in harsh rolling environments and protection against dust,
liquids, vapours and corrosive substances. Based on the magnetostatic principle, the design of the press head enables the production of measurement signals without the
need for compressive deformation of the sensor body. From a mechanical point of view, the pillow indenter is effectively a solid block of stainless steel with a high coefficient
of elasticity, and its strength and stiffness are critical for applications where overload protection and sensitivity to vibration are important. Some indenters are capable of
withstanding overloads of up to 30 times the rated tension.
Vertical Measuring Pillow Indenter
PFCL 201C/CE 5 - 50 kN
The vertical pillow indenter is ideal for rolling mills and treatment lines (annealing, pickling, galvanising lines, etc.). The press head is made from a single piece of
stainless steel, has a high coefficient of elasticity and is extremely robust. It is able to be mounted under the bearing housing to measure the vertical component force,
which can be measured in both directions.
The indenter is available in three versions:
- PFCL 201C, fitted with Cannon connectors for connecting cables, very suitable for handling lines.
- PFCL 201CD, fitted with 20 metres of PTFE fixed connection cable, a solution for handling line applications.
- PFCL 201CE, for mill environments, fitted with a fixed connection cable with sheath, ideal for mill applications.
Pillow presses
PFCL241-SE 200 kN
The press head PFCL241-SE is ideal for multi-roll mills and other mill applications with high strip tension. It can also be used for high tension applications in processing lines. This press head is
a solid tension gauge made from a single piece of stainless steel.
This press head is a solid tensiometer made from a single piece of stainless steel with a high coefficient of elasticity similar to that of other Pressductor pillow block press heads and is extremely rugged.
It can be mounted under the bearing housing to measure the vertical component force and can be used in both directions.The PFCL241-SE is suitable for use in rolling mill environments and is supplied
with a sheathed, fixed connection cable.
Vertical Measurement Customised Millmate Strip Tension Measurement System Indenter
PFBL 141B/C 4 - 400 kN
Customised indenter - designed to meet your mill and specific needs.
This vertical measuring Millmate Strip Tension Measuring System indenter features a highly proven design that allows for accurate measurements in the harshest environments,
such as the middle stand of a cold rolling mill. Another application is measurement in multi-roll mills - where precise tension control is key.
This type of indenter is very sensitive to vertical forces, but not to lateral forces. Two versions of this type of indenter are available for fixed or rotating rollers.
Pillow indenter for transverse measurement
PFTL 201C/CE/D/DE 10 - 100 kN
The transverse pillow indenter is mainly used for measurements on treatment lines such as annealing, pickling and galvanising lines.
The transverse division of force is well suited for measuring strip tension. The indenter only measures the strip tension, not the roll weight. Measurements are taken
with the highest possible accuracy.
The solid stainless steel design offers excellent sensitivity, accuracy and robustness as well as a high coefficient of elasticity.
- PFTL 201C/D , fitted with Cannon connectors for cable connection, very suitable for handling lines.
- PFTL 201CE/DE, suitable for mill environments, fitted with a fixed connection cable with sheath.
Control Unit:
Millmate 400 Controller
The Millmate 400 Controller, is capable of providing a wide range of functions while being easy to use. The control unit has a variety of built-in mechanical mounting modes.
This means that the user only needs to follow a step-by-step menu to set up the control unit and make the correct strip tension calculations.
