Total Customer Satisfaction –PCB

Piezotronics guarantees Total Customer

Satisfaction. If, at any time, for any

reason, you are not completely satisfied

with any PCB product, PCB will repair,

replace, or exchange it at no charge.

You may also choose to have your

purchase price refunded in lieu of the

repair, replacement, or exchange of the

product.

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 insure 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 insure that your

returned materials are handled in the

most expedient manner. Before

Warranty, Service, Repair, and

Return Policies and Instructions

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

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.

OPERATION MANUAL FOR

MICROPHONE

Series 103A 1

1.0 DESCRIPTION

The Series 103A microphones are high-sensitivity

pressure sensors featuring miniature size, built-in

solid state electronics and acceleration compensation.

The Model 103A (see installation drawing) has

pigtail leads extending radially from the side of the

unit and has a nominal sensitivity of 1500 mV/psi.

The Model 103A11 is similar in appearance and in

mode of electrical connection, but differs from the

Model 103A in that the sensitivity is nominally 500

mV/psi.

Models 103A and 103A11: ICP® Sound Pressure

Sensors

The Model 103A02 is similar physically to the 103A

and has similar sensitivity (1500 mV/psi), but the

electrical connection is made through a top mounted

10-32 coaxial connector.

The Model 103A12 also has the top connector like

the 103A02 but the sensitivity is 500 mV/psi.

These units are ideal for wind tunnel testing of

models because of the small size and high sensitivity.

Models 103A02 and 103A12: ICP®Sound

Pressure Sensors

2.0 DESCRIPTION

(Refer to installation drawing no. 103-1010-90

included as part of this manual.)

The 103A Series Sensors utilize a bimorph bender

crystal cantilevered from the side wall and attached to

the center of a thin recessed invar diaphragm.

Pressure acting on the surface of the diaphragm

results in a net force which strains (or deflects) the

diaphragm in proportion to the applied pressure. The

diaphragm bends the crystal creating an output

voltage which is also proportional to applied

pressure.

This voltage is fed to the gate of a miniature

MOSFET source follower amplifier which reduces

the output impedance to less than 100 Ohms allowing

the driving of long cables and permitting operating

directly into most readout instruments.

Refer to Bulletin G-0001B, “General Guide to ICP®

Instrumentation”for a detailed description of the

built-in amplifier concept.

Models 103A, A02, A11, and A12 have output

signals superimposed upon a +4 V (approx.) bias

level at the amplifier output. All PCB signal

conditioners are designed to eliminate this bias

voltage while supplying power to the internal

amplifier.

OPERATION MANUAL FOR

MICROPHONE

Series 103A 2

The result is a two-wire system, precluding the need

for multi-conductor cabling.

A second diaphragm, located behind the pressure

diaphragm and attached to another bimorph bender

crystal acting in opposition to the pressure crystal,

provides acceleration compensation to the Series

103A Sensors.

3.0 INSTALLATION

As shown in installation drawing 103-1010-90, the

Series 103A Microphones may be properly mounted

in several ways, the exact method chosen being a

function of the space available along with other use

dictated parameters.

The simplest method of mounting, and also the one

that utilizes the least volume, is the adhesive method.

The microphone is simply bonded directly to the

mounting surface with an (at least) .10”diameter hole

through the surface to feed the pressure signal to the

diaphragm.

Many different types of adhesives may be used to

bond the 103A in this manner. The important point

being to apply the adhesive very sparingly so that

removal does not damage the sensor.

The 103A may also be mounted using the Model

061A04 Servo clamps if space is available.

The Model 060A11 Clamp Nut may only be used

with the top connector Models 103A02 and 103A12

since the radial wire leads of the Model 103A and

103A11 would interfere with the clamp nut. The

installation drawing gives detailed instructions on

preparation of the port for this type of installation.

3.1 ELECTRICAL

For the Models 103A and 103A11 (pigtail models),

connect the center conductor from the “Xducer”

output of any ICP®power unit to the white (Pwr/Sig)

lead and connect the outer shell of the “Xducer”

connector to the black (ground) lead. The black lead

is electrically connected to the outer case. (See figure

below.)

Models 103A & All: Electrical Connection

NOTE: No electrical connection is made to the

blue (vent) lead. This lead serves to vent internal

pressure within the sensor when the 103A and

103A11 are used in evacuated chambers. The

internal pressure bleeds out slowly around the wires

of this lead. This lead may be cut off flush with body

if the sensor will never be used in this manner.

To make the electrical connection to the Models

103A02 and 103A12 (top connector models), simply

connect the “Xducer”output of the power unit to the

10-32 coaxial connector using a PCB Model 002C

Series coaxial cable.

The output signal is taken from the power unit

connector labeled “Scope”or “Output”. (See figure

below.)

OPERATION MANUAL FOR

Series 103A 3

Refer to Guide G-0001B for tips on power and signal

utilization.

NOTE: The internal low-noise amplifier in the

Model 103A, A02, A11 and A12 differ from the

standard ICP®amplifiers described in Guide G-

0001B in that the turn-on (or bias) voltage is

nominally +4 volts.

Proper turn-on for Models 103A02, A11 and Al 2

will not give center scale reading on the fault monitor

meters found on most PCB signal conditioners but

will show a reading of approximately 20% of F.S. on

these meters. This puts it at the lower limit of the

green (or normal) area of the meters. This is normal

and in no way indicates faulty operation.

4.0 OUTPUT SIGNAL

The output signal from the 103A Series is a voltage

proportional to input pressure. The polarity is

positive-going for increasing input pressure.

The signal is of high enough level and low enough

output impedance to be fed directly into most

oscilloscopes, tape recorders, strip chart recorders, A

to D converters, etc.

Consult the factory for information regarding galvo

driving since special amplifiers are needed to drive

most high-current galvanometers.

Low-frequency response is limited by sensor

discharge TC (given in the specification sheet) and by

coupling time constants throughout the system. To

take full advantage of the TC of the sensor, make sure

that coupling TC's from power unit to readout are at

least an order of magnitude longer than the discharge

TC or use a direct-coupled signal conditioner such as

the Model 484B. Consult factory for details.

5.0 CALIBRATION

The 103A Series Sensors must be dynamically

calibrated using a known step function or pulse, or

with a microphone calibrator.

At PCB, the units are subjected to various calibrated

steps of pneumatic pressure to obtain a linearity curve

over the full range of the instruments.

6.0 MAINTENANCE AND REPAIR

The small size and sealed construction of the Series

103A precludes field maintenance and repair.

Should the time constant degrade or an abnormality

appear in the normal bias voltage, bake the unit out in

a +250° F oven for 1 to 2 hours, then re-test.

If this is not effective or if other problems should

occur, contact the factory for assistance in tracing the

problem or for instructions on returning the unit for

repair.

7.0 PRECAUTIONS

l.) Do not apply voltage to the unit without a

current-limiting device in the line such as

incorporated in all PCB signal conditioners, (20 mA

maximum) to do so will destroy the internal amplifier.

2.) Do not subject these units to temperatures

higher than 250° F.

3.) Do not attempt to disassemble these units as

to do so voids the warranty.

4.) Use caution when removing units that have

been mounted with epoxies or other strong adhesives.

Excessive squeezing or torquing may damage the

units and/or cause a calibration shift.

5.) In vibratory environments, secure cables and

leads to surrounding structures to avoid lead or cable

damage.

6.) Do not over torque when using the Servo

clamps or the clamp nut since this could damage the

units.

7.) Do not overpressure (see specs for

maximum pressure), to do so may change the

calibration.
