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.

Operation and Wiring
Standard Wiring
The Model 640/641/645/646 B Series operates from a standard 2-Wire, 4-20mA loop. If using a loop powered
unit, attach the positive (+) input from the power supply to Pin A or Red wire on the sensor and the negative (-)
input from the power supply to Pin B or Blue Wire of the sensor.
Figure 1 –wiring: loop powered Figure 2 –wiring: loop powered/DC source
If using a standard DC power supply, install either an ammeter and/or load resistor in line with the output, Pin B or
Blue Wire.
The resistor will generate a DC voltage that is proportional to current by:
V = IR
If R = 500 ohms and I = 6 mA, then V = 3 VDC
Note:
- Resistor value must be less than: (Vsupply –12) x 50.
- For integral cable sensors: RED wire is positive, BLUE wire is negative.

PAGE 6
Taking Measurements
When measuring the current output from the unit, use the following formula to calculate the vibration level:
Vibration Output = (Measured Output –4mA) x (Full Scale Vibration Output /16mA)
Measured mA 640BX0 640BX1 640BX2

RV Option
The RV (raw vibration) option includes a 100mV/g ±20% additional output. The accelerometer frequency range is
1 Hz-1 kHz, maximum amplitude of 15 g-pk. Data collectors or analyzers can use this vibration signal for further
analysis. This output is extended to the RVVO (Raw Vibration Velocity Output) option, which integrates the signal
to a value of 100 mV/IPS (±20%).
Figure 3 –RV and RVVO wiring
For integral cable sensors:
RED 4-20mA Positive
BLACK 4-20mA Negative (same as green)
GREEN –RV and RVVO negative (same as black)
WHITE +RV and RVVO positive
Note:
-The RV and RVVO Signal Negative has to be isolated from any grounding. If this terminal is grounded, the 4-
20mA loop will short, causing no output.
-The RV and RVVO output signal is ideally suited for use with portable battery powered data collectors or
analyzers.

PAGE 8
TO Option
The TO (Temperature Output) option includes an additional independent 4-20mA output for temperature
measurement. The temperature range is from -40°C to 125°C with an overall accuracy of ±5%FSO. The
imbedded temperature sensor monitors the environment internal to the sensor housing and is situated at
approximately mid level.
Figure 4 –TO wiring
For integral cable sensors:
RED 4-20mA Vibration Positive
BLACK 4-20mA Vibration Negative
GREEN 4-20mA Temperature Negative
WHITE 4-20mA Temperature Positive
Note:
- The same power supply can be used for both 4-20mA loops. Connect both positive terminals directly to the
power supply, then use the negative terminals for independent process loops.

Installation
When choosing a mounting method, consider closely the advantages and disadvantages of each technique.
Typical mounting types are stud, direct adhesive, adhesive mounting base and magnetic mounting base. Since
the frequency response is limited to 1 kHz on the 640/641, any of the four methods can be used without seriously
affecting the data values. The mounting method might affect some of the 645/646 series because of the
increased frequency response.
Direct Adhesive Mount Procedure
For restrictions of space or for convenience, most sensors (with the exception of integral stud models) can be
adhesive-mounted directly to the machine surface.
STEP 1 Prepare a smooth, flat surface. A minimum surface finish of 63 µin [0.0016 mm] generally works best.
STEP 2 Place a small portion of adhesive on the underside of the sensor. Firmly press down on the top of the
assembly to displace any adhesive. Be aware that excessive amounts of adhesive can make sensor removal
difficult.
Figure 5–direct adhesive mounting

PAGE 10
Standard Stud Mount Procedure
This mounting technique requires smooth, flat contact surfaces for proper operation and is recommended for
permanent and/or secure installations. Stud mounting is also recommended when testing at high frequencies.
Note: DO NOT attempt mounting on curved, rough or uneven sufaces, as the potential for misalignmen and
limited contact surface may significantly reduce the senor’s upeer operating frequnecy range.

A (in) 0.250 0.250
B (in) 0.350 0.350
Torque (ft-lb) 2 to 5 2 to 5
STEP 1 First, prepare a smooth, flat mounting surface, and then drill and tap a mounting hole in the center of this
area as shown in Figure 6. A precision-machines mounting surface with a minimum finish of 63 µin [0.0016 mm] is
recommended. (If it is not possible to properly prepare the machine surface, consider using an adhesive mounting
pad as a possible alternative.) Inspect the area, checking that there are no burrs or other foreign particles
interfering with the contact surface.
STEP 2 Wipe clean the mounting surface and spread on a light film of grease, oil or similar coupling fluid prior to
installation.
Figure 7–mounting surface lubrication.
Adding a coupling fluid improves vibration transmissibiliy by filling small voids in the mounting surface and
increasing the mounting stiffness. For semi-ermanent mounting, substitue epoxy or another type of adhesvie.
STEP 3 HAND –tighten the sensor/mounting stud to the machine, then secure the sensor with a torque wrench
to the mounting surface by applying the recommended mounting torue ( see enclosed specification data sheet for
proper mounting torque). It is important to use a toque wrench during this step. Under-toruing the sensor may
not adequately couple the device; over-torquing may result in stud failure and possible permanent
damage.

PAGE 11
Adhesive Stud Mount Procedure
Adhesive mounting is often used for temporary installation or when the machine surface cannot be adequately
prepared for stud mounting. Adhesives like hot glue or wax work well for temporary mounts; two-part epoxies and
quick –bonding gels provide a more permanent mount.
Note: Adhesively mounted sensors often exhibit a reduction in high-frequency range. Generally, smooth surfaces
and stiff adhesvies provide the best frequency response.
This method involves attaching a base to the machine surface, then securing the snesor to the base. This alows
for easy removal of the accelerometer.
STEP 1 Prepare a smooth, flat mounting surface. A minimum surface finish of 63 µin [0.0016 mm] generally
works best.
STEP 2 Stud-mount the sensor to the appropriate adhesive mounting base according to the guidelines set forth in
Steps 2 and 3 of the Standard Stud Mount Procedure.
STEP 3 Place a small portion of adhesive on the underside of the mounting base. Firmly press down on the
assembly to displace any extra adhesive remaining under the base.
Figure 8–mounting base: adhesive installation

PAGE 12
Magnetic Mount Procedure
Magnetic mounting provides a convenient means for making portable measurements and is commonly used for
machinery monitoring and other portable or tending applications.
Note: The correct magnet choice and an adequately prepared mounting surface is critical for obtaining reliable
measurements, especially at high frequencies. Poot installations can cause as much as a 50% drop in the sensor
frequency range.
Not every magnet is suitable for all applications. For example, rare earth magnets are commonly used
because of their high strength. Flat magners work well on smooth, flat surfaces, while dual-rail magnets
are required for curved surfaces. In the case o non-magnetic or rough surfaces, it is recommended that
the user first weld, epocy or otherwise adhere a stell mounting pad to the test surface. This provides a
smooth and repeatable location for mounting.
Figure 9–magnet types
STEP 1 After choosing the correct magnet type, inspect the unit, verifying that the mounting surfaces are flat and
smooth.
STEP 2 Stud- mount the accelerometer to the appropriate magnet according to the guidelines set forth in Steps 2
and 3 of the Standard Stud Mount Procedure.
STEP 3 Prepare a smooth, flat mounting surface. A minimum surface finish of 63 µin [0.0016 mm] generally
works best. After cleaning the surface and checking for burrs, wipe on a light film of silicone grease, machine oil
or similar-type coupling fluid.
STEP 4 Mount the magnet/sensor assembly to the prepared test surface by gently ‘rocking” or “sliding” it into
place.
Note: Magnetically mounting accelerometers carelessly as the potential to generate very high ( and very
damaging) g levels. To prevent damage, install the assembly gently. If unsure, please contact the factory for
assistance.

Warning 1 –ESD sensitivity
The power supply/signal conditioner should not be opened by anyone other than qualified service
personnel. This product is intended for use by qualified personnel who recognize shock hazards and are familiar
with the safety precautions required to avoid injury.
Warning 2 –ESD sensitivity
This equipment is designed with user safety in mind; however, the protection provided by the equipment may be
impaired if the equipment is used in a manner not specified by PCB Piezotronics, Inc.
Caution 1 –ESD sensitivity
Cables can kill your equipment. High voltage electrostatic discharge (ESD) can damage electrical devices.
Similar to a capacitor, a cable can hold a charge caused by triboelectric transfer, such as that which occurs in the
following:
Laying on and moving across a rug,
Any movement through air,
The action of rolling out a cable, and/or
Contact with a non-grounded person.
The solution for product safety:
Connect the cables only with the AC power off.
Temporarily “short” the end of the cable before attaching it to any signal input or output.
Caution 2 –ESD sensitivity
ESD considerations should be made prior to performing any internal adjustments on the equipment. Any
piece of electronic equipment is vulnerable to ESD when opened for adjustments. Internal adjustments should
therefore be done ONLY at an ESD-safe work area. Many products have ESD protection, but the level of
protection may be exceeded by extremely high voltage.
