Product overview
The MAGPOWR TS web tension sensors are extremely accurate
devices used to measure tension in any unwind, rewind, or
intermediate web processing application. The unique low profile
design minimizes space requirements inside the machine frames,
thus maximizing the potential for web width. The TS model
sensors also offer the flexibility of a variety of mounting styles
and coupling options.
MAGPOWR web tension sensors are ruggedly constructed with
mechanical overload stops in both force directions to eliminate
sensor damage and the need to recalibrate even after extreme
overloads. A full Wheatstone bridge arrangement of four foil
strain gages is used in each sensor for the most accurate means
of measuring web tension. In addition, all sensors incorporate a
dual beam construction design to insure linear output under all
loading conditions.
The TS style tension sensors can be mounted to the machine side
frame in one of several ways. They can be mounted on a vertical
surface using the Stud mount model, or the Flange mount model,
or to a horizontal surface using the Pillow Block model.
The TS style tension sensors allow three methods of coupling to
the customer’s application. The coupling types are Split
couplings, In-Roll coupling and Wire Pulley.
The TS style tension sensors allow any combination of mounting
and coupling types.

Mounting and coupling options
The Split Coupling configuration supports the customer’s dead or live shaft on each side of the
machine.
The In-Roll configuration supports the customer’s roll assembly (hollow tube) on each side of
the machine.
The Wire Pulley coupling configuration supports the single strand or wire, and measures tension
in the wire or strand as it passes over the pulley.

Basic safety
information
Proper use
The load cell devices are intended to be used on machines or
systems to monitor the tension in a web.
Indoor operation.
Improper use
Operation outside the technical specifications
Operation in an Ex-area or intrinsically safe area without a
proper barrier.
Any other use than the proper use shall be deemed inappropriate
Installation and commissioning
Any load cell device that is damaged must not be installed or put
into operation.
Only perform installation, maintenance or repair tasks on the
load cell device when the machine has been stopped and is
secured from being turned on.
Only perform installation, maintenance or repair tasks on the
load cell device when there is no electrical power in the system.
The load cell device must be securely mounted before being
placed in operation.
No modifications may be made to the load cell device.
Do not place electrical cables under mechanical strain.
Maintenance and repair
Warning –Danger of injury from crushing
Maintenance and repair tasks on the load cell device must be
performed only when the machine has been stopped and has
been secured from being turned on again.
Decommissioning
The load cell must be disposed of in accordance with all the
applicable national, state and local regulations.

Mechanical and electrical
installation
CAUTION –Possible damage to load cell.
Do not hammer on the load cell.
CAUTION –Possible damage to load cell.
Do not disassemble the load cell –there are no serviceable
parts inside the unit.
WARNING –Danger of injury from crushing.
Maintenance and repair tasks on the load cell device must
be performed only when the machine has been stopped and
has been secured from being turned on again.
General
Select a clean flat surface where the wrap angle of the web
does not change. Position the vertical centerline of the
sensor so that it bisects the wrap angle of the web.
If the orientation of the sensor requires the force direction
arrow to be pointed opposite the resultant tension force
direction, then the black (-S) and the white (+S) sensor
leads to the MAGPOWR readout or control terminal block
must be reversed.
Stud mount
Fasten to the machine frame with a bolt making sure that
the bolt penetration does not exceed 12.7 mm [0.50 in]. A
small hole is provided in the rear of the sensor to accept a
pin to aid in alignment.
Flange mount
For the flange mounted version, fasten to the machine
frame with 4 bolts.
Pillow block mount
For the pillow block style, mount the pillow block adapter
with two bolts. A series of holes is provided in the pillow
block adapter to allow alignment of the sensor with the
resultant force.

INSTALLATION

MAGPOWR TS Load Cell
MI 850A342 1 A
Mechanical and electrical
installation
(continued)
Shaft and roll assembly (supplied by customer)
The sensor split coupling or in-roll coupling can accommodate
shaft misalignment of 0.001 mm/mm [0.001 in/in].
Example: For 600 mm between machine side frames, the sensor
must be aligned within .600 mm.
Split coupling models
Split coupling sensors can be used for both live and dead shaft
applications. All split coupling sensors are shipped with the
coupling locked in place for use with a dead shaft. For live shaft
applications remove the anti-rotation screw located behind the
removable part of the split coupling.
Remove the coupling screws and top half of the couplings. Gently
lower the shaft/roller assembly into the couplings. The couplings
have some misalignment capability to facilitate shaft mounting.
Replace one coupling top half and screws. Tighten screws
securely. Push this coupling toward the machine frame, and hold
it in position while securing the coupling on the other end of the
shaft. This will divide the thermal expansion capability between
the two sensors.
In-roll coupling models
Insert one sensor into each end of a machined tube and install between machine frames
accordingly.
