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

OPERATION MANUAL FOR MICROSENSORS

132 Series

1.0 INTRODUCTION

132 Series Microsensors are small, piezoelectric

pressure sensors featuring extremely fast response for

measurement of short wavelength pressure pulses.

The short time constant of some models filters off the

longer duration portion of pressure pulses, allowing

differentiation of consecutive pressure pulses.

132 Series Microsensors contain integrated ICP



circuit amplifiers which operate as source followers

and provide very high-frequency response. These

micro-integrated circuit amplifiers convert the high-

impedance voltage from the crystals into low-

impedance voltage of less than 100 ohms.

Output from the microsensors may be coupled

directly into oscilloscopes, recorders and A to D

converters. Power to operate the IC amplifier and the

output signal are conducted over a single conductor,

two-wire cable with the ground serving as signal

return. Special low-noise cables are not required.

The calibrated mV/psi output of these microsensors is

not attenuated nor is noise appreciably increased by

the cable.

2.0 DESCRIPTION

132 Series Microsensors feature small diameter

pressure-sensing surfaces incorporating very small (<

1 mm) piezoelectric sensing elements. The small size

of the sensing elements imparts extremely fast

response time to the microsensors.

The charge generated by deflection of the

piezoelectric element when subjected to shock

pressures creates a voltage on the input capacitance at

the gate of the microsensor ICP



amplifier. The

amplifier, in conjunction with the source element,

transforms the input into a low-impedance output

signal of equal amplitude. The DC bias that exists on

the signal lead is removed from the output signal by a

coupling capacitor in the power supply. Resistors in

the internal ICP



amplifiers of the microsensors set

the internal discharge time constant, which

determines the low-frequency response of the

microsensors. (Refer to General Guide to ICP



Instrumentation, G-0001, for complete details.)

Below are the available configurations for the 132

Series Microsensors.

3.0 INSTALLATION

Refer to the installation drawing for details. If the

microsensors are to be subjected to pressures beyond

their specified range, be sure to use backing nuts to

prevent the sensors from backing out of their

mounting ports. (Thread adaptors are available from

PCB to facilitate mounting.)

Connect the microsensors to an ICP



power supply.

Use standard two-conductor cable between the sensor

and the ICP



power unit.

Next, connect the power unit to a readout device, e.g.,

oscilloscope, recorder or high-speed A to D

converter.

4.0 OPERATION

Switch the ICP



power unit on and observe reading of

bias-monitoring voltmeter on front panel of power

unit.

If indicator is in green section of indicator panel, the

IC amplifier is providing proper bias (normally +11

VDC), cable connections are normal and the system

is ready to operate.

If the needle moves to the red area of the fault

monitor meter, output is zero and a short is indicated.

The short could be located in the amplifier cable

connectors or in the power unit.

If the pointer moves into the yellow area of the fault

monitor meter, an open circuit is indicated with full

power supply voltage. An open circuit could be the

result of a faulty amplifier, an open cable or open

connectors.

Allow the sensor to thermally stabilize for about one

minute. A signal drift may occur when the output

cable is connected to the readout instrument.

The drift occurs during charging of the coupling

capacitor in the power unit. The signal will stabilize

in several minutes.

132 Series

4.1 OPERATION BEYOND RANGE

SPECIFICATION

Because 132 Series Microsensors can be installed

using RTV-like potting materials to hold them in

place, maximum pressure specifications are given to

prevent the sensors from being extruded from the

mounting holes. Static or slow dynamic

overpressures are more apt to cause a problem than a

short dynamic shock pulse. Use of backing nuts will

minimize the possibility of a problem.

The microsensors are capable of responding to

dynamic overpressures up to ten times the specified

range. The output will be “clipped” (look flat-topped

on the readout) after about 10 volts.

The initial rise of the output will be accurate up to the

point of clipping. This can allow for an accurate

time-of-arrival measurement, even though the peak

pressure cannot be measured.

5.0 CALIBRATION

A shock tube is used to calibrate the microsensors.

6.0 MAINTENANCE AND REPAIR

Except for repair of wires, the microsensors are not

field-repairable. In case of serious malfunction,

contact the PCB at (888) 684-0011.

It is well to observe the following precautions in

using the microsensors:

1. Do not exceed specified pressure levels without

proper mounting.

2. Do not subject microsensors to temperatures

exceeding 174 °F (79 °C).

3. Do not apply voltage to sensors without current-

limiting diodes or other current protection. (PCB

ICP



power supplies feature proper voltage and

current protection.)

4. Do not apply more than 20 mA of current to the

microsensors.
