MTS Enhances Mobile Hydraulic Sensors for Rugged Applications

CARY, NC - (April 4, 2007) - MTS Systems Corp., Sensors Division has built upon its
proven mobile hydraulic position sensor technology with the development of an even
more robust MH sensor. Combining proven Temposonics® technology with a redesigned
lid that provides a stronger wire/cable connection, the MH sensor is ideal for use in
welded and tie-rod cylinders, or any space-limited cylinder applications.

"Over the last three years, our experience with customers has proven that the MH
sensor is extremely reliable once installed inside the hydraulic cylinder, even when
subjected to the harsh conditions found in off-highway machinery," said Drew Smedley,
director of global marketing for MTS Sensors. "One need that customers identified was a
more robust wire/cable exit design, primarily to help prevent damage to seals during the installation process."

In response, MTS engineers developed a sealing system that is more robust to
typical handling during installation.

"Most importantly, we designed the mechanics to be completely compatible with
the existing design for embedded, in-cylinder applications," Smedley said.

With a 100g shock and 25g vibration rating, the MH sensor was designed for
rugged environments, especially those typically encountered in construction, agriculture, and other off-highway machinery.

The MH sensor consists of a redesigned sensor head with rugged housing and
built-in electronics, a pressure-proof sensor pipe that protects the internal sensing
element, and a position magnet. Along with high shock and vibration ratings, the sensor
has 200V/m EMI protection.

Designed for cylinders two inches in diameter (or larger), the MH sensor now
provides a measuring range of two to 78 inches (50-2500mm), doubling the available
stroke length, while maintaining high levels of accuracy and repeatability.

The MH sensor provides four position output options: 0 to 5V, 0 to 20mA, 4 to
20mA, or PWM (16 re-circulations). It is available with a simultaneous velocity output
for more precise closed-loop control capability. The MH sensor operates from -40 to
+105°C, and can be purchased with either individual wire or cable connection options
that are compatible with typical mobile equipment electrical connector requirements.
M-Series sensors meet ISO14982 standards for agricultural and forest machines
and ISO7637-0/1/2 standards for road vehicles, and are CE-certified. The MH sensor can
be installed from the head side or the rod side of the cylinder depending on the cylinder
