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

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.
