MTS Sensors' Linear Position Sensors Provide Precise Feedback In Hydraulic Levelers


Magnetostrictive technology ensures quality in end-products...

CARY, N.C. (May 7, 2008) - MTS Systems Corp., Sensors Division's
Temposonics® linear-position sensors provide high accuracy for repeatability and
uniform production quality in hydraulic roller leveling applications. The magnetostrictive sensors can be embedded inside the hydraulic cylinders or affixed outside the cylinders that control the leveling machine movement for producing metal plates and slabs. The MTS linear position sensor is an ideal fit for this application because it offers high accuracy that ensures consistency and repeatability, which is critical for supplying metal to industries such as aerospace, military, automotive, and transportation.

"The main function of the R-Series SSI sensor in leveling is ensuring the precise
position of the rolls throughout the leveling process in order to produce a smooth, flat slab that is level and within end-user specification," said Temposonics Marketing
Manager, Matt Hankinson. "The R-Series' superior response and accuracy result in
higher machine performance and part quality."

The rugged, reliable, non-contact sensor construction results in reduced
maintenance and down time, while high shock and vibration tolerance and superior EMI
and noise immunity ensure trouble-free operation. The sensors also enable customers to
store pre-set configurations for a wide variety of product shapes and sizes, reducing
startup and changeover times.

By optimizing the hydraulic rolling leveler's performance, MTS' magnetostrictive
linear position sensors offer superior accuracy with higher consistency between
changeovers and reduced setup time; precise and repeatable positioning for smoother,
more controlled motion; and improved efficiency, yield, and throughput while
maintaining quality. This results in higher overall productivity to the machine operator.

The R-Series SSI sensor provides the same absolute serial encoder interface
(Synchronous Serial Interface) widely used in the servocontrol industry. Design
flexibility and field adjustability of data format, position resolution, and polarity and synchronization parameters are facilitated through the use of an easy-to-use PC interface programming software. This flexibility allows controls engineers to accommodate a range of control interfaces and mechanical system variations within a common location, thereby helping to reduce sensor inventory.

The SSI output of the R-Series sensor product is fast, with an optional data update
rate of 250 ìsec synchronized with an external control clock. MTS' proprietary
synchronization technology guarantees the most accurate position output while
minimizing inherent system-related delays to produce smooth, precise control.
The R-Series SSI product features position sensing resolution as low as 1 micron
(0.00004 in), which is factory or field-adjustable. For higher accuracy requirements, an optional internal linearization improves the sensing accuracy to as low as +/-20 ìm,
depending on the mechanical application package.

The Temposonics model RH rod-style sensors are designed for internal mounting
in applications where high-pressure conditions exist (5,000 psi continuous/ 10,000 psi
spike), such as hydraulic cylinders, and come in stroke lengths up to 7.6 m (300 inch.). With its unique electronics removable cartridge design, the model RH sensor offer users the ability to replace the sensing electronics in the field quickly and easily without the need to remove the sensor housing and break the high-pressure hydraulic seal.

Model RP "profile"-style sensors utilize a lightweight but rigid aluminum
extrusion with sensing lengths of up to 5 m (200 inch.) and include two different magnetmounting configurations: captive sliding magnet or floating magnet. The IP 67-rated RPstyle sensors are used in applications where installation inside a hydraulic or pneumatic cylinder is not possible. They are well-suited for space-restrictive environments where there are high levels of dust and contamination. In addition, RP-style sensors can be externally mounted on machines via mounting brackets and configured with a variety of connector options.

Temposonics hydraulic-style sensors are pre-configured at the factory by model
code designation. For most applications, no adjustments are required for normal sensor
installation and operation, but if sensor parameters need to be changed on-site, the
sensors are easy to program using one of three options - handheld or cabinet mounted
pushbutton programmers or PC software programming kits depending on the user's
needs.
