Service, Repair, and Return
Policies and Instructions

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 ISO­9001 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

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

Introduction

The Model 682A09 Series Industrial in line ICP to 4-20mA converter transfers the signal from any 100 mV/g ICP
industrial accelerometer to 4-20mA overall vibration velocity. The converter outputs a 4-20mA signal that is
proportional to the overall velocity and raw acceleration of the machinery. Ideal for monitoring the vibration of
process equipment such as fans, motors and pumps, the output of the converter is routed to a PLC, DCS or
SCADA system and used for process control or predictive maintenance.

General Features

• Loop powered, works with an open analog channel on PLC, DCS or SCADA system.

• Vibration range in velocity scaled for 0-1 inches per second peak

• Allows for continuous vibration monitoring of critical applications.

• Reduces the need for sophisticated vibration analysis requirements.

• RV (Raw Vibration) output for conducting frequency analysis and machinery diagnostics.

• Readily interfaces to existing process control and predictive maintenance equipment.

• Rugged stainless steel construction for applications in harsh environments.

Operation and Wiring

Standard Wiring

The Model 682A09 Series operates from a standard 2-wire, 4-20mA loop. If using a loop power, attach at 3-Pin
connector side the positive (+) input from the power supply to Pin A and the negative (-) input from the power
supply to Pin B. Pin C is a buffered raw acceleration output (Fig. 1). At ICP side (2-Pin connector) attach Pin A (+)
to positive terminal of ICP sensor and Pin B (-) to negative (common) terminal of ICP sensor (Fig. 2).

Suggested Cabling

For connecting 100 mV/g ICP accelerometer to 682A09 converter:

IMI suggests using model 052APXXXAP cable where XXX is the cable length in feet. For example, model
052AP010AP is a 10 ft. polyurethane cable, 2-socket MIL (AP) on each end. The 2-socket MIL connector (AP)
mates to most any 2-pin MIL industrial accelerometer and also the model 682A09. Pictures of this cable and

connector can be found at IMI’s website www.imisensors.com.

For connecting 682A09 converter to PLC, DCS, SCADA system:

IMI suggests using model 059BVXXXBZ cable where XXX is the cable length in feet. For example, model
059BV010BZ is a 10 ft. polyurethane cable, 3-socket MIL (BV) to blunt termination. The 3-socket MIL (BV)
connector mates to the output of the 682A09. Wiring to acquisition is color coded as follows:

Red - connect to pos (+) loop-powered input on PLC, DCS, SCADA system

Black or Green – connect to neg (-) loop-power input on PLC, DCS, SCADA system

White – 100 mV/g analog sensor signal for frequency analysis, route to BNC for walk-up measurement
with portable data collector

RV Output

The RV (raw vibration) output is a pass-through for the 100 mV/g industrial accelerometer connected to the
model 682A09. The frequency range and accuracy of the signal will be dependent upon the accelerometer used.
Data collectors or analyzers can use this vibration signal for further analysis. Contact IMI if you require more
information on the accelerometer being connected to model 682A09.

Notes:

- The RV Signal Negative has to be isolated from any grounding. If this terminal is grounded, the 4­20mA loop will short, causing no output.

- The RV output signal is ideally suited for use with portable battery powered data collectors or
analyzers.
