The information contained in this document supersedes all similar information that
may be found elsewhere in this manual.
Service –Due to the sophisticated
nature of the sensors and associated
instrumentation provided by PCB
Piezotronics, user servicing or repair is
not recommended and, if attempted,
may void the factory warranty. Routine
maintenance, such as the cleaning of
electrical connectors, housings, and
mounting surfaces with solutions and
techniques that will not harm the
physical material of construction, is
acceptable. Caution should be observed
to ensure that liquids are not permitted
to migrate into devices that are not
hermetically sealed. Such devices
should only be wiped with a dampened
cloth and never submerged or have
liquids poured upon them.
Repair –In the event that equipment
becomes damaged or ceases to
operate, arrangements should be made
to return the equipment to PCB
Piezotronics for repair. User servicing or
repair is not recommended and, if
attempted, may void the factory
warranty.
Calibration –Routine calibration of
sensors and associated instrumentation
is recommended as this helps build
confidence in measurement accuracy
and acquired data. Equipment
calibration cycles are typically
established by the users own quality
regimen. When in doubt about a
calibration cycle, a good “rule of thumb”
is to recalibrate on an annual basis. It is
also good practice to recalibrate after
exposure to any severe temperature
extreme, shock, load, or other
environmental influence, or prior to any
critical test.
PCB Piezotronics maintains an ISO-
9001 certified metrology laboratory and
offers calibration services, which are
accredited by A2LA to ISO/IEC 17025,
with full traceability to SI through
N.I.S.T. In addition to the normally
supplied calibration, special testing is
also available, such as: sensitivity at
elevated or cryogenic temperatures,
phase response, extended high or low
frequency response, extended range,
leak testing, hydrostatic pressure
testing, and others. For information on
standard recalibration services or
special testing, contact your local PCB
Piezotronics distributor, sales
representative, or factory customer
service representative.
Returning Equipment –Following
these procedures will ensure that your
returned materials are handled in the
most expedient manner. Before
returning any equipment to PCB
Piezotronics, contact your local
distributor, sales representative, or
factory customer service representative
to obtain a Return Warranty, Service,
Repair, and Return Policies and
Instructions Materials Authorization
(RMA) Number. This RMA number
should be clearly marked on the outside
of all package(s) and on the packing
Service, Repair, and Return
Policies and Instructions

list(s) accompanying the shipment. A
detailed account of the nature of the
problem(s) being experienced with the
equipment should also be included
inside the package(s) containing any
returned materials.
A Purchase Order, included with the
returned materials, will expedite the
turn-around of serviced equipment. It is
recommended to include authorization
on the Purchase Order for PCB to
proceed with any repairs, as long as
they do not exceed 50% of the
replacement cost of the returned
item(s). PCB will provide a price
quotation or replacement
recommendation for any item whose
repair costs would exceed 50% of
replacement cost, or any item that is not
economically feasible to repair. For
routine calibration services, the
Purchase Order should include
authorization to proceed and return at
current pricing, which can be obtained
from a factory customer service
representative.
Contact Information –International
customers should direct all inquiries to
their local distributor or sales office. A
complete list of distributors and offices
can be found at www.pcb.com.
Customers within the United States may
contact their local sales representative
or a factory customer service
representative. A complete list of sales
representatives can be found at
www.pcb.com. Toll-free telephone
numbers for a factory customer service
representative, in the division
responsible for this product, can be

16-BIT TORKDISCROTARY TORQUE SENSOR SYSTEM OPERATION MANUAL

3.3 Theory of Operation
The TORKDISCsystem utilizes a unique digital data transmission technique. A radio frequency signal
generated within the receiver box is inductively coupled from the pick-up antenna to the transmitting antenna
and rectified to provide DC voltages to operate the rotating TORKDISCtransmitter. The transmitter has been
configured for a full-scale input of ±1.5mV/V. The rotating circuitry provides excitation for the strain gage
bridge, amplifies, and filters its output. The resulting signal is presented to an analog to digital converter that
samples it and converts it to a noise immune digital code. To provide up to a 8.5kHz measurement bandwidth
without creating aliasing errors, the A-to-D converter samples at a rate in excess of 26,000 samples per second.
Data bits are transmitted off the rotor in this digitally encoded form. In this manner, they are not subject to
noise degradation or "per rev" effects.
The digital data bits are recovered in the receiver box where they are re-converted to an analog signal. This
signal is used to generate the standard voltage output, consult the factory for optional frequency system outputs.
The specified bandwidth represents the electronic capability of the TORKDISCSystem only and does not
reflect actual installed system performance and the influence of sensor and system mechanics. It is advisable
that the customer model the entire drive line with the sensor installed and /or conduct an in-situ torsional
vibration analysis to determine the measurement bandwidth.
The calibration of the TORKDISCsystem is easy to accomplish and is extremely stable over time. The
product is equipped with a remotely activated shunt calibration feature that can be controlled from the front
panel of the receiver box. This allows the user to check calibration at any time during system operation. When
the shunt calibration feature is invoked, a precision resistor is switched across one leg of the Wheatstone bridge,
producing a positive shift in the receiver’s output.
