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,

1.0 Description
Series 8162 Strain Gage Signal Conditioners provide
conditioned, amplified analog voltage and current
output for strain gage based sensors such as load cells
and reaction torque sensors. The units operate from
12 to 28 V
DC
power, and deliver ± 5 or ± 10 V and 4
to 20 mA output signals for recording, control, and
analysis purposes.
Figure 1 - Series 8162 Signal Conditioner
The Series 8162 Signal Conditioners provide a wide
strain gage input range from 0.5 to 11 mV/V, and are
housed in fire resistant, waterproof NEMA 4X (IP66)
enclosures. Standard features include an integral
shunt calibration switch with an internal resistor, a
two-pole active filter with 100 Hz cut-off, and
watertight compression fittings for easy installation.
Typically, Series 8162 Signal Conditioners are
configured to operate with a specific transducer
during system calibration at the factory. Therefore,
internal adjustments are not normally required prior
to initial use. However, should adjustments be
needed, the following sections outline instructions to
configure the conditioner to other specific
applications.
2.0 Power Connection
The Series 8162 Signal Conditioner is designed to
operate on a customer supplied DC power source
with a voltage range of 12 to 28 volts. To connect
power to the conditioner,
a. Loosen the four screws on top of the box and
remove the lid to expose the internal circuit
board.
b. Insert a power cable through one of compression
fittings located on the side of the unit.
c. Prepare the wire leads of the cable, then insert
the input voltage wire into the screw 1 position
on terminal J1. Reference Figure 4 for the J1
terminal location. Tighten the screw to fasten
the wire in place.
d. Next, insert the Ground wire into the screw 2
position on terminal J1. Tighten the screw to
fasten the wire.
3.0 Transducer Cabling
High quality twisted pair shielded cable with four
conductors is recommended (such as Belden 8723)
for transducer hook up. PCB can supply finished
cables for transducers with either a PT02E-10-6P or
PC04E-10-6P receptacle if desired.
To connect the transducer to the conditioner, insert
the interconnect cable through a compression fitting,
then screw attach to terminal J2 per the arrangement
outlined in Table 1 below.
Table 1 – Transducer Cabling
+Signal (Green) Screw 1
–Signal (White) Screw 2
–Excitation (Black) Screw 3
+Excitation (Red) Screw 4
4.0 Analog Outputs
Two analog outputs are available on the 8162 Series
Signal Conditioner. The first is a voltage output that
is jumper selectable to either ±5 or ±10 volts. The
desired voltage output is set by the position of the P2
Jumper. Jumping pins 1 and 2 will set the
conditioner to ±10 V
OUT
. Jumping pins 2 and 3 will
set the conditioner to ±5 V
OUT
. Adjust Zero Balance
and Span by using the R23, R29, and R22
potentiometers on the conditioner’s internal circuit
board. Refer to Figure 4. Note that Zero Balance has
both a coarse and fine adjustment.
A 4 to 20 mA current output is the second available
output. The current output is adjusted using the R5
and R20 potentiometers. Reference Figure 4 for
exact locations of the potentiometers.
Connecting output instrumentation to the signal
conditioner is accomplished by attaching an
interconnect cable to terminal J3 on the conditioner’s
internal circuit board. Voltage output is fastened to
screw 4; current output is attached to screw 1.
Ground leads may be attached to either screw 2 or 3.
5.0 Transducer Excitation

SERIES 8162 STRAIN GAGE SIGNAL CONDITIONER MANUAL
3
Either 5-volt or 10-volt bridge excitation can be
selected. In general, 5-volt excitation is used with
120Ωtransducers, and the 10-volt excitation is used
with 350Ωand 700Ωtransducers.
Excitation voltage is set by the position of the P1
Jumper. See Figure 4. Jumping pins 1 and 2 will set
the conditioner to 10 V
EXC
. Jumping pins 2 and 3
will set the conditioner to 5 V
EXC
.
6.0 Calibration
The Series 8162 can be calibrated using (2) different
methods. The first method uses actual or simulated
Zero and Full Scale (FS) inputs. Actual inputs may
come from a strain gage transducer loaded with
calibrated weights. Simulated inputs may come from
a strain gage bridge simulator.
The second method utilizes an R
CAL
resistor to
simulate a load on a strain gage bridge. The R
CAL
resistor, located in the R12 position in Figure 4, is
shunted across one arm of the strain gage bridge
when the R
CAL
Switch (SW1) is depressed. The
shunt produces an imbalance equivalent to that of a
particular value of mechanical input. If this
Equivalent Input value is accurately known, it can be
used as a reference point for shunt calibration of the
system. Upon completion of installation of the
transducer and its associated cabling, the user can:
a. Perform an overall deadweight calibration using
a precisely known value of mechanical input.
The calibration can then be transferred to the
installed calibration resistor for convenience in
checking later.
b. Replace the installed calibration resistor with
one supplied by the transducer manufacturer, or
an equivalent resistance value, to achieve a
precisely known equivalent input, allowing the
instrument sensitivity to be adjusted correctly.
c. A 30K ohm resistor is installed at the factory and
is used during final checkout of the instrument.
It is replaced with a more proper value resistor
when calibrated with a specific transducer to
produce a more accurate shunt value. The
resistor is mounted internally on terminal R12
located on the printed circuit board in the
instrument. See Figure 4. It can be reached by
removing the cover.
Note: Soldering is not required to remove or install
the shunt calibration resistor. When an amplifier is
purchased with a specific sensor as a system, PCB
will install the proper value shunt resistor in the
amplifier.
R
CAL
Polarity (+R
CAL
/ -R
CAL
)
The default R
CAL
polarity setting of the Series 8162
Signal Conditioner is positive (+). Depending on the
particular sensor being calibrated with the
conditioner, +R
CAL
and/or -R
CAL
data is provided on
the calibration certificate.
The polarity of the R
CAL
may be switched by
changing the solder jumper position on the R
CAL
solder tabs located on the internal circuit board of the
conditioner. See Figure 4 for the R
CAL
solder tab
locations. Solder applied to jumper 1 will yield a
+R
CAL
, solder applied to jumper 2 will yield a -R
CAL
.

7.0 Gain Switch
Table 2 illustrates the proper Gain switch settings on switch block SW2 (shown in Figure 4) based on the input
signal from the sensor with which it is used. Set each of the four switches to either 1 (ON) or 0 (OFF) according to
the sensor’s excitation voltage and sensitivity.
