with regulations governing the geographical location and facility.
Only install equipment that complies with the types of protection
relevant to the applicable Classes, Zones, Divisions and Groups.
3. In explosive atmospheres use only such auxiliary components
that meet all requirements of the local and national standards.
4. The potential equalisation of the system has to be established
according to the regulations of erection applicable in the
respective country of use (VDE 0100 part 540; IEC 364-5-54).
5. Sensors from MTS Sensors are approved only for the intended
use in industrial environments (see chapter “2.1 Intended use”
on page 3). Contact the manufacturer for advice if aggressive
substances are present in the sensor environment.
6. Measures for lightning protection have to be taken by the user.
7. The user is responsible for the mechanical protection of the
sensor.
8. The sensor may be used only for fixed installations with
permanently wired cables. The user shall ensure that cables and
cable glands correspond to the risk assessment of the hazardous
application as well as to thermic, chemical and mechanical
environmental conditions. The user is also responsible for the
required strain relief. When selecting the sealing, the maximum
thermal load of the cables must be taken into account.
9. The user is responsible for meeting all safety conditions as
outlined by:
• Installation instructions
• Local prevailing standards and regulations
10. Any parts of the equipment which got stuck (e.g. by frost or
corrosion) may not be removed by force if potentially

How to ensure safe commissioning
1. Protect the sensor against mechanical damage during
installation and operation.
2. Do not use damaged products and secure them against uninten-
tional commissioning. Mark damaged products as being
defective.
3. Prevent electrostatic charges.
4. Do not use the sensor in cathodic systems for corrosion
protection. Do not allow parasitic currents on the sensor housing.
5. Switch off the supply voltage prior to disconnecting or
connecting the connectors.
6. Connect the sensor very carefully and pay attention to the
polarity of connections, power supply as well as to the shape
and duration of control pulses.
7. Cable entry temperature and branching point temperature may
reach 104 °C (219 °F) and 116 °C (241 °F) respectively. Select
suitable cable and entry device.
8. For field wiring, use cables suitable for the service temperature
range of −40 °C (−40 °F) to +116 °C (241 °F).
9. Do not open when energized. Open the sensor only as shown in
Fig. 6 on page 13.
10. A seal shall be installed within 18"of the enclosure (for NEC /
CEC only).
11. Use only approved power supplies of Category II according to
IEC 61010-1.
12. Ensure that the specified permissible limit values of the sensor
for operating voltage, environmental conditions, etc. are met.
13. Make sure that:
• the sensor and associated components were installed
according to the instructions
• the sensor enclosure is clean
• all screws (only those of quality 6.8, A2-50 or A4-50 are
allowed) are tightened according to specified fastening
torque in Fig. 6
• the cable glands certified according to the required
hazardous area classification and IP protection are tightened
according to the manufacture’s specifications
• surfaces limiting the joint shall not be machined or painted
subsequently (flameproof enclosure)
• surfaces limiting the joint have not been provided with a seal
(flameproof enclosure)
• the magnet does not grind on the rod. This could cause
damage to the magnet and the sensor rod. If there is contact
between the moving magnet (including the magnet holder)
and the sensor rod, make sure that the maximum speed of the
moving magnet is less or equal 1 m/s.
14. Ground the sensor via one of the two ground lugs. Both the
sensor and the moving magnet including magnet holder must
be connected to protective ground (PE) to avoid electrostatic
discharge (ESD).
15. Before applying power, ensure that nobody’s safety is
jeopardized by starting machines.
16. Check the function of the sensor regularly and provide
documentation of the checks
(see chapter “6.2 Maintenance” on page 32).
2.4 Safety instructions for use in explosion-hazardous areas
The sensor has been designed for operation inside explosion-hazard-
ed areas. It has been tested and left the factory in a condition in which
it is safe to operate. Relevant regulations and standards have been ob-
served. According to the marking (ATEX, IECEx, CEC, NEC, KCs, EAC
Ex, Japanese approval) the sensor is approved only for operation in de-
fined hazardous areas (see chapter “2.1 Intended use” on page 3).

Application
Temposonics®position sensors are used for measurement and
conversion of the length (position) variable in the fields of automated
systems and mechanical engineering.
The T-Series sensors are designed for installation in a raised or flat-
face flanged hydraulic cylinder, for use as an open-air position sensor
or as a liquid level sensor with the addition of a float.
Principle of operation and system construction
The absolute, linear position sensors provided by MTS Sensors
rely on the company’s proprietary Temposonics®magnetostrictive
technology, which can determine position with a high level of
precision and robustness. Each Temposonics®position sensor
consists of a ferromagnetic waveguide, a position magnet, a strain
pulse converter and supporting electronics. The magnet, connected
to the object in motion in the application, generates a magnetic field
at its location on the waveguide. A short current pulse is applied to
the waveguide. This creates a momentary radial magnetic field and
torsional strain on the waveguide. The momentary interaction of the
magnetic fields releases a torsional strain pulse that propagates the
length of the waveguide. When the ultrasonic wave reaches the end of
the waveguide it is converted into an electrical signal. Since the speed
of the ultrasonic wave in the waveguide is precisely known, the time
required to receive the return signal can be converted into a linear
position measurement with both high accuracy and repeatability.

Installation of TH with threaded flange
Fix the sensor rod via threaded flange M18×1.5-6g or ¾"-16 UNF-3A.
Fig. 9: Mounting example of threaded flange
Installation of a rod-style sensor in a fluid cylinder
The rod-style version has been developed for direct stroke
measurement in a fluid cylinder. Mount the sensor via threaded flange
or a hex nut.
• Mounted on the face of the piston, the position magnet travels
over the rod without touching it and indicates the exact position
through the rod wall – independent of the hydraulic fluid.
• The pressure resistant sensor rod is installed into a bore in the
piston rod.
Fig. 10: Sensor in cylinder
Hydraulics sealing for threaded flange with raised-face

4.3 Magnet installation
NOTICE
Mount ring magnets and U-magnets concentrically.
The maximum permissible air gap must not be exceeded (Fig. 15).
Take care to mount the primary sensor axis in parallel to the magnet
path in order to avoid damage to the carriage, magnet and sensor
rod.
Typical use of magnets
Mounting ring magnets & U-magnets
Install the magnet using non-magnetic material for mounting
device, screws, spacers etc.. The magnet must not grind on
the sensor rod. Alignment errors are compensated via the air gap.
• Permissible surface pressure: Max. 40 N/mm2
• Fastening torque for M4 screws: 1 Nm; use washers, if necessary
• Minimum distance between position magnet and any magnetic
material has to be 15 mm (0.6 in.) (Fig. 16).
• If no other option exists and magnetic material is used, observe the
specified dimensions (Fig. 16).
Fig. 14: Typical use of magnets
Magnet mounting with magnetic material
When using magnetic material the dimensions of Fig. 16 must
be observed.
A.If the position magnet aligns with the drilled piston rod
B.If the position magnet is set further into the drilled piston rod, install
another non-magnetic spacer (e.g. part no. 400 633) above the
magnet.

Magnet Benefits
Ring magnets • Rotationally symmetrical magnetic field
U-magnets • Height tolerances can be compensated,
because the magnet can be lifted off
Floats • For liquid level measurement

Operation Manual
NOTICE
On all sensors, the areas left and right of the active stroke length are
provided for null and dead zone. These zones should not be used for
measurement, however the active stroke length can be exceeded.
Controlling design dimensions are in millimeters and measurements in ( ) are in inches
Sensors with stroke lengths ≥ 1 meter (3.3 ft.)
Support horizontally installed sensors with a stroke length from 1 meter
(3.3 ft.) mechanically at the rod end. Without the use of a support, rod
and position magnet may be damaged. A false measurement result
is also possible. Longer rods require evenly distributed mechanical
support over the entire length (e.g. part no. 561 481). Use an U-magnet
(Fig. 17) for measurement.
Start and end positions of the position magnets
Consider the start and end positions of the position magnets during
the installation. To ensure that the entire stroke length is electrically
usable, the position magnet must be mechanically mounted as follows.
Mounting floats
A stop collar is ordered separately with a float. The stop collar
consists of material, which is below the specific gravity of the fluid. It
is designed to keep the float out of the dead zone. The placement of
the stop collar is dependent on the float and placement of the magnet
within the float. If your application requires measuring to the bottom
of your vessel, ask MTS Sensors about our low lift-off float option.
Differentiation measurement
For a differentiation measurement two positions are measured on the
sensor rod. The distance between these positions will be output.
NOTICE
Do not go below a minimal distance of 75 mm (3 in.) between the
magnets for differentiation measurement. 4Use magnets of the
same type (e.g. two ring magnets with part no. 201 542-2) for
differentiation measurement.

Operation Manual
4.4 Electrical connection
Placement of installation and cabling have decisive influence on the
sensor‘s electromagnetic compatibility (EMC). Hence correct
installation of this active electronic system and the EMC of the entire
system must be ensured by using shielded cables and grounding.
Overvoltages or faulty connections can damage the sensor electronics
– despite protection – against wrong polarity.
Instruction for connection
• Remove the cover plate as shown in Fig. 6 on page 13 to connect
the cables to the sensor.
• If you use a cable / cable gland use low-resistance twisted pair and
shielded cables. Connect the shield to ground externally via the
controller equipment.
• Keep control and signal leads separate from power cables and
sufficiently far away from motor cables, frequency inverters, valve
cables, relays, etc..
• Install a conductor of 4 mm2cross section to one of the two
external ground lugs.
• Keep all non-shielded leads as short as possible.
• Keep the ground connections as short as possible with a large cross
section. Avoid ground loops.
• Use only stabilized power supplies in compliance with the specified
electrical ratings.
NOTICE
1. Do not mount the sensors in the area of strong magnetic or
electric noise fields.
2. Never connect / disconnect the sensor when voltage is applied.
NOTICE
The contactable cross section is 0.2…2.5 mm² and 0.2…1.5 mm².
Only 1 wire per clamping point is allowed!
Connector wiring
Connect the sensor directly to the control system, indicator or other
evaluating systems as follows:
