Benefits of magnetostrictive sensing
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 movable permanent
magnet that passes along the outside of the sensor. The other field
comes from an “interrogation” current pulse applied along the wave-
guide. The resulting strain pulse travels at ultrasonic 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 applica-
tion of the interrogation pulse and the arrival of the resulting strain
pulse with a high-speed counter. Elapsed time is used to determine
the permanent magnet position which provides an absolute position
reading that never requires recalibration or re-homing after a power
loss. Non-contact sensing eliminates wear, and guarantees the best
durability and output repeatability.
Product overview
Today’s buyers are more concerned with greater productivity,
lower overall operating costs and cost of ownership. Temposonics
M-Series Mobile Equipment sensors help lower overall costs by
increasing safety and versatility, increasing reliability and reducing
service costs. Temposonics Mobile Equipment sensors are designed
specifically for position sensing applications in rugged environments
typically encountered by construction, agriculture and other off-
highway machinery. All Temposonics Mobile Equipment sensors
utilize magnetostrictive technology.
The M-Series, Model MH sensor with analog output, is one of the
latest compact stainless-steel position sensors specifically designed
for use in welded and tie-rod style cylinders, or any space limited cyl-
inder application. The M-Series Model MH sensor is an ideal choice
for a wide range of standard hydraulic cylinders with diameters of 50
mm (1.97 in.) or larger.
The extremely rugged model MH sensor consists of the following
main components:
1. The sensor head; A robust housing with built-in electronics.
2. The pressure-proof sensor pipe; The sensor pipe houses and
protects the internal sensing element.
3. The position magnet; The magnet is mounted on the piston, during
operation it travels along the stationary sensor tube. This sensor
system is “non-contact” by design.
All specifications are subject to change. Contact MTS for specifications and engineering

M-Series Model MH Analog Sensor product specifications and dimensions
Temposonics Model MH high-pressure compact sensor
M-Series sensors were designed with the “mobile” world in mind, and
have been validated in the field by customers worldwide. Performance
is second-to-none; high accuracy, repeatability, 200 V/m EMI, and
position output.
Ruggedness is “designed in”; 100 g shock and 25 g vibration rating.
Cable and wire options are sized for direct connection to industry
proven connectors. The model MH sensor is fully sealed and when
embedded in a cylinder provides a long operating life.

M-Series Model MH, Analog Output Sensor - Specification 550824 I
M-Series Model MH Analog Sensor installation, wiring examples and magnets
The robust Temposonics Model MH sensor’s new stainless-steel position sensor is designed for direct stroke measurement in standard compact
hydraulic cylinders. The Temposonics Model MH sensor can be installed from the head side or the rod side of the cylinder depending on the
cylinder design.
Sensor installation
The method of installation is entirely dependent on the cylinder design. While the most common method of installation is from the rod side of
the cylinder, installation from the head side of the cylinder is also possible. In both installation methods, the sensor seals the cylinder by using
an O-Ring and backup ring which is installed on the sensor housing.
