Repair and Maintenance
PCB guarantees Total Customer Satisfaction through its
“Lifetime Warranty Plus” on all Platinum Stock Products
sold by PCB and through its limited warranties on all other
PCB Stock, Standard and Special products. Due to the
sophisticated nature of our sensors and associated
instrumentation, field servicing and repair is not
recommended and, if attempted, will void the factory
warranty.
Beyond routine calibration and battery replacements
where applicable, our products require no user
maintenance. Clean electrical connectors, housings, and
mounting surfaces with solutions and techniques that will
not harm the material of construction. Observe caution
when using liquids near devices that are not hermetically
sealed. Such devices should only be wiped with a
dampened cloth—never saturated or submerged.
In the event that equipment becomes damaged or ceases
to operate, our Application Engineers are here to support
your troubleshooting efforts 24 hours a day, 7 days a
week. Call or email with model and serial number as well
as a brief description of the problem.
Calibration
Routine calibration of sensors and associated
instrumentation is necessary to maintain measurement
accuracy. We recommend calibrating on an annual basis,
after exposure to any extreme environmental influence,
or prior to any critical test.
PCB Piezotronics is an ISO-9001 certified company whose
calibration services are accredited by A2LA to ISO/IEC
17025, with full traceability to SI through N.I.S.T. In
addition to our standard calibration services, we also offer
specialized tests, including: sensitivity at elevated or
cryogenic temperatures, phase response, extended high
or low frequency response, extended range, leak testing,
hydrostatic pressure testing, and others. For more
information, contact your local PCB Piezotronics
distributor, sales representative, or factory customer
service representative.
Returning Equipment
If factory repair is required, our representatives will
provide you with a Return Material Authorization (RMA)
number, which we use to reference any information you
have already provided and expedite the repair process.
This number should be clearly marked on the outside of
all returned package(s) and on any packing list(s)
accompanying the shipment.

The 422E series in-line charge converters are designed to convert the high impedance of a charge
mode piezoelectric transducer to a low-impedance voltage by means of an ICP ® signal conditioner.
These units may be used with either quartz or ceramic charge-mode piezoelectric sensors.
description
The 422E series in-line charge amplifiers operate from an ICP ® signal conditioner. The unit employs a
high gain amplifier to perform the impedance transformation. The charge output of the transducers
may be scaled in terms of acceleration, pressure or force. The output is then mV/g, mV/psi or mV/lb,
respectively.
installation
Connect the 422E series to the transducer with low-noise cable (003A) only. Standard coaxial or two-
wire cable may be used between the amplifier and the signal conditioner, and between the signal
conditioner and the readout device.
Note: For optimum noise performance, the cable length between the sensor and the 422E should be
minimized.
operation
To operate, simply connect the input of the 422E to the transducer using low-noise (003A) cable and
the output to any ICP ® signal conditioner using standard cable. The output of the signal conditioner
may then be connected to an oscilloscope or other monitoring device. This output will be an AC signal
(see specification for actual frequency response) with a DC bias. Many PCB signal conditioners
remove the bias via an AC coupling circuit.

The 422E contains a high-gain, low-noise amplifier connected in a charge amplifier configuration. The
charge output of the transducer is transferred to the feedback capacitor of the amplifier to develop a
voltage which may be calculated using the following equation.
Vout = 422E Scaling (mV/pC) x Transducer Sensitivity (pC/Engineering Unit)
where:
Vout = Output of 422E in mV/Engineering Unit
the Engineering Unit may be g’s, Newtons, psi, etc., depending on the sensor
Example: A 357A12 (3 pC/g) is used with a 422E02 (10 mV/pC). Calculate the output in mV/g.
Answer: 10 mV/pC x 3 pC/g = 30 mV/g
TEDS functionality
422E units with a “T” prefix incorporate TEDS (Transducer Electronic Data Sheet) technology. Using a
TEDS capable signal conditioner, or TEDS reader, the user is able to read calibration data stored in the
sensor. Some systems allow the user to also write user data and calibration information to the 422E.
All data is formatted in accordance with IEEE 1451.4.

High source capacitance may degrade the performance of the 422E (source capacitance is the input
capacitance defined as transducer capacitance + cable capacitance). In particular, noise may increase
and high frequency response may decrease if source capacitance exceeds the recommended level. In
some cases, low frequency oscillation of the output may occur. The maximum recommended level in
pF’s is determined using the following formula:
maximum recommended source capacitance = 10,000/422E sensitivity in mV/pC
For example, the level for a 422E02/E12 would be 10,000/10 pF = 1,000 pF, and the level for a
422E03/E13 would be 10,000 pF. If PCB 003 type low noise cable is used, these values correspond to
10 meters and 100 meters of length respectively.
422E series models for use with high temperature sensors
The 422E35 (1 mV/pC) and 422E36 (10 mV/pC) have been specifically designed to operate with the
lower insulation resistance values which piezoelectric sensors may exhibit when subjected to very high
temperatures (generally greater than 500°F). Both units will operate with insulation resistances as low
as 10kΩ.
Note: Because of the special circuitry required, the 422E35 and 422E36 have somewhat higher noise
and longer turn on time than the equivalent units designed for use with sensors with high insulation
resistance (the 422E03 and 422E02 respectively). Consult the specifications for details.
Caution! Excessive accumulated charges on the input cables can destroy the field effect transistor
(FET) in the amplifier. These charges can be grounded by shorting the center pin on the cable
connector plug to its knurled nut with any metallic object.
