Benets of Magnetostriction
Temposonics linear-position sensors use the time-based
magnetostrictive position sensing principle developed by MTS.
Within the sensing element, a sonic-strain pulse is induced in a
specially designed magnetostrictive waveguide by the momentary
interaction of two magnetic fields. One field comes from a moveable
permanent magnet that passes along the outside of the sensor. The
other field comes from an “interrogation” current pulse applied along
the waveguide. The resulting strain pulse travels at sonic speed along
the waveguide and is detected at the head of the sensing element.
The position of the magnet is determined with high precision and speed
by accurately measuring the elapsed time between the application of
the interrogation pulse and the arrival of the resulting strain pulse with
a high-speed counter. The elapsed time measurement is directly pro-
portional to the position of the permanent magnet and is an absolute
value. Therefore, the sensor's output signal corresponds to absolute
position, instead of incremental, and never requires recalibration or re-
homing after a power loss. Absolute, non-contact sensing eliminates
wear, and guarantees the best durability and output repeatability.

Product overview
MTS offers the Model RF Flexible housing as an option with our
R-Series family of extremely robust, highly accurate, linear-position
sensors.
Constructing a R-Series sensor with the RF flexible housing results
in a flexible style sensor that offers trouble-free performance
in applications that require very long stroke lengths and linear
measurements on an arc.
The Model RF flexible sensors are available in all R-Series sensor
outputs including analog, serial, digital, and bus interfaces.
Standard stroke lengths for the sensor are up to 10 meters (396
in.) and for special applications, longer lengths are available by
consulting the factory.
Flexible sensors incorporate the Temposonics SE (Sensing Element)
technology that is the same building block all MTS sensor models
use. The SE is housed in a fluoroelastomer coated stainless steel
housing that is flexible and can be bent in an arc to an 8 inch
minimum bend radius.
Most operating parameters are identical to their rigid cousins.
Model RF sensors are recommended for long-length applications
because they are simply coiled inside a 40-inch diameter box for
shipping, which simplifies logistics and handling.
The model RF sensor can easily bend around corners or obstacles
and provides a simple solution for applications where installation
space is too confined, or has limited access, making installation or
replacement too difficult and costly for a standard rigid type sensor.
Output options
The Model RF Flexible Housing option is available for R-Series
Sensors with voltage, current, SSI, CANbus, DeviceNet, Profibus,
EtherCAT and EtherNet/IP outputs.
Important specification notes:
1. For R-Series model specific specifications, consult the individual
R-Series data sheets applicable to the sensor output(s) being used.
2. All sensors constructed with the flexible housing have their
specifications measured while laying flat.

Sensor mounting and Installation references
R-SERIES MODEL RF SENSOR MOUNTING AND INSTALLATION Flexible installation in any position!
The model RF flexible sensor housing can be mounted to provide straight or curvilinear measurements. The sensor's flexible housing
requires supports or anchoring to maintain proper alignment between the sensor rod and the magnet. Without proper alignment, the
sensor's output signal can be interrupted or lost.
A hex flange comes mounted on the sensor head having either U.S. customary threads (3/4 - 16 UNF inches) or metric threads (M18 x 1.5).
The flange is secured to the sensor head by 2 metric screws (M4 x 59 mm, 2.5 mm hex socket head). The flange can be used, or removed,
to best accommodate the installation requirements. If the sensor is mounted without the flange, the red grommet seal can be cut off to
provide a flush mounting surface for the sensor’s face seal O-Ring (shown in 'Figure 1' on page 3 and 'Figure 2' below).

When installed inside the MTS half-inch O.D. pressure housing pipe, the RF flexible sensor housing is suitable for use in hydraulic cylinders,
and can simplify installation where installation or mounting space is limited (see 'Figure 7').
Half inch O.D. pressure pipe and flange (Optional)
PIPE AND FLANGE SELECTIONS
The half inch O.D. pressure pipe with flange is designed specifically for R-Series sensors with the model RF flexible housing option. The
pressure pipe and flange provide protection from high pressures, as found in hydraulic cylinders, up to 5,000 psi static, 10,000 psi spike. For
large cylinders, using the half-inch O.D. pressure pipe requires a larger gun-drilled bore in the piston head/rod assembly. Typically, a 0.75
inch bore is used to match the I.D. of the ring magnet used (e.g. part no.: 201554 or part no.: 400424).
