Liability and guarantee 2
1.3 Liability and guarantee
Emerson is not liable for damages which were caused by improper use. The proper use also
includes knowledge and attention of this operating manual.
Changes at the device, that are not permitted particularly by Emerson, will lead to the loss of
the guarantee.
Due to continuous research and product development, Emerson reserves the right to change
the specification without notice.
1.4 Repair and maintenance
During operation, the sensor PR 9350 as well as the set K 20 315 do not require any mainten
ance.
If work with the opened device on site is unavoidable, this should only be performed by a
specialist who is familiar with the associated hazards.
If repair or calibration of a PR 9350 or K 20 315 is required, it must be sent to Emerson. Attach
a non-detachable tag bearing customer name and defect observed to the sensor respectively
set. Refer to product service centers in the beginning of this manual for the address.
1.5 Storage and transport
The devices may only be stored or forwarded in their original packing or by using an equival
ent packing. The environmental conditions for storage and transport are specified in the

5Using the device
Chapter 2: Safety Instructions
The device has left the factory in a faultless condition in regards to safety regulations. To
preserve this condition and to ensure a safe operation, all instructions in this manual must be
observed carefully.
The correct and safe use of this device requires, that operating and service personnel is familiar
with generally valid safety guidelines, complies with them and observes the special safety
comments, listed in this manual. Where necessary, safety sensitive points on the device are
marked.
DANGER
Since the sensor is an electrical equipment, commissioning and service may only be made
by trained personnel. Maintenance may only be carried out by trained, specialized and
experienced personnel.
2.1 Using the device
The linear displacement transducer PR 9350 as well as the set K 20 315 are designed for meas
urement of static and dynamic displacements. The sensor should only be used for measure
ment purposes.
2.2 Radio interference suppression, EMC
The device is carefully shielded and tested to be technically immune to radio interference and
complies with current standards. When operating together with other peripheral devices, that
are not properly shielded against radio interference, disturbances and radio interferences may
occur.

Owner's responsibility 6
2.3 Owner's responsibility
If there is a reason to suspect, that hazard-free operation and thus adequate machine
protection is no longer possible, the device must be taken out of operation and safeguarded
from unintentional operation. This is the case
•if the device shows visible damages
•if the device no longer works
•after any kind of overload (e.g. storage, transport) that has exceeded the
permissible limits.
DANGER
If tests with the sensor has to be carried out during operation or if the sensor has to be
replaced or decommissioned, it has to be taken into account, that this will impair the
machine protection and may cause the shut down of the machine due to opening electrical
circuits.
For this reason, the machine protection has to be deactivated by the responsible staff,
before starting such work.
Having finished the work, the machine protection has to be activated again immediately by
the responsible staff.
2.4 Instructions on ESD safety
DANGER
Internal components can be damaged or destroyed due to electrostatic discharges when
handling the sensor.
Consequently, prior to handling the sensor, suitable measures must be taken to prevent
electrostatic discharges via the sensor electronics (e.g. ESD bracelet).Transport and storage
of electronic components may only be made in ESD-safe packaging.
At dry meteorological conditions with relative humidity below 30 %, electrostatic
discharges can appear more frequently. In this case the sensor must be handled with
particular care when maintenance and repair works have to be made.

Chapter 3: Application & Design
3.1 Application
The inductive transducers PR 9350 or the set K 20 315 serve the measurement of static and
dynamic displacements and - in connection with carrier frequency measuring bridges - of
physical quantities (tensile and compressive forces, pressure of gases and liquids, thickness
of materials, transverse moments) which may in any way be converted to linear movements
by using relevant accessories.
The special features of these transducers are a high resolution over the entire measuring
range, small hysteresis, compact construction and the little mass of the tracing pin (solenoid
plunger). Thus, the controlling forces on the measuring target may be neglected.
The temperature drift is extremely small because the compensation coil is wound directly
over the measuring coil.
Installation of these transducers are imaginably easy. The transducer permits dynamic
measurements up to 1250Hz.
The differential coil of the PR 9350 series consists of a coil form with two windings and a
tracing pin with a ferromagnetic core which moves within the coil. If the tracing pin is placed
precisely in the middle of the coil, the impedance of both windings are identical. The
impedance of the windings will increase on one side and decrease on the other side - if the
tracing pin with the ferromagnetic core moves from the middle position to one end of the
transducer.
By complementing the windings with resistors to a Wheatstone bridge, and by supplying this
bridge with a carrier frequency, the measuring output of the bridge reads a voltage which is
proportional to the displacement of the tracing pin. The tracing pin is freely movable and has
a threaded rod (M3) for the mechanical adaptation to the measuring target. On top of the
housing there is a 3-pole Cannon socket for the electric connection. Inductive transducers of
type PR 9350 or the set K 20 315 are preferably used with the MMS 3410 transmitter or with
the A 6410 monitor.
The PR 9350 is available with several measuring ranges from ±12mm up to ±150mm.
The set K 20 315 consists of a PR 9350 sensor mounted in a housing inclusive connection
cable.

Chapter 5: Function check
The PR 9350 sensor can be checked by measuring the internal sensor resistance at the connec
tion terminals of the sensor (for pin assignment see Figure 5). This resistance is an indicator for
sensor problems. Table 3 shows resistances and their meaning.
CAUTION
Before starting this work, inform the responsible specialist and, if necessary, let them
deactivate the machine protection.
Having finished the work, the machine protection has to be reactivated immediately by the
responsible staff.
