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.

1.0 Description
Series 8161 Signal Conditioner/Amplifier is designed for use with strain gage transducers that
can operate with a DC excitation-amplification source. The 8161 series supplies either a 5 volt
or a 10 volt transducer excitation, which can be selected through an internal jumper (see Figure
1). The 8161 series contains all necessary balancing, gain, and calibration controls and
conditions/amplifies the applied input to a standard +/-5 or +/- 10 volt (jumper selectable, see
Figure 1), and 4-20 mA analog output. Calibration of the instrument to the transducer is made
through conventional a shunt technique using an internal calibration resistor. A front panel push
button provides for calibration in the positive direction.
2.0 Power connection
The 8161 series is designed to operate on a customer supplied DC power source with a voltage
range of 10 to 28 volts. Screw terminals 1 and 2 are provided for power connections. Reference
Figure 3.
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 receptacles if desired. Reference Figure 3 for transducer hook
up.

4.0 Transducer excitation
Either 5 volt or 10 volt bridge excitation can be selected (see Figure 1). In general, 5-volt
excitation is used with 120Ωtransducers, and the 10-volt excitation is used with 350Ωand 700Ω
transducers.
5.0 Calibration Resistor
If a fixed resistor is shunted across one arm of a strain gage bridge, it 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:
1. 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.
2. 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.
A 30K ohm resistor is installed at the factory and is used during final checkout of the instrument.
It should be replaced with the proper value and accuracy for the transducer that it will be used
with. The resistor is mounted internally on terminals located on the printed circuit board in the
instrument. It can be reached by removing the cover.
Note: Soldering is not required to remove or install the shunt calibration resistor. When
amplifier is purchased with a specific sensor as a system, PCB will install the proper
value shunt resistor in the amplifier.
6.0 Analog Outputs
Two different analog outputs are available at the instrument terminal connections. Each output
has a 1,000 Hz cutoff frequency. The voltage output of ±5 volts or ±10 volt @ 5 mA (jumper
selectable) is available between terminals 4and 1. The current output of 4 to 20 mA is available
between terminals 3and 1.
7.0 Calibration
This section contains the instructions for calibrating the Model 8161 series. To perform
calibration, proceed as follows:
1. Set SW2 switches to appropriate mV/V setting. See location in Figure 2.

2. Hookup transducer as shown in Figure 3, then connect power supply.
3. Apply DC power (10 to 28 volts) to terminals 1 and 2 (see Figure 3). Allow 30 minutes
of warm-up time for stabilization of transducer characteristics.
4. With the transducer unloaded, set the voltage output to ZERO using the coarse and fine
zero controls. If the current output is to be used, set ZERO to 4 mA using the 4 mA
adjust.
5. Load the transducer to a convenient up-scale value, which is greater than one half of full
scale. Adjust the fine span control until the voltage output signal reading is equal to the
dead weight value. Remove the dead weight, then press the RCAL switch and note the
voltage reading obtained. This reading can now be used in future calibrations since it is
related to a value obtained thru dead weight calibration. To calibrate the instrument in
the future, simply press the CAL button and adjust the fine span control to obtain the

reading previously recorded after dead weight calibration. If the current output is to be
used, repeat the above step using the 20 mA adjust.
6. If dead weight calibration is not practical and the transducer manufacturer has supplied a
calibration resistor (or resistor value), install the recommended calibration resistor. Now
press the RCAL switch and adjust the voltage and/or current controls until the module
output is equal to the Equivalent Input value simulated by the installed calibration
resistor.
7. If dead weight calibration is not practical and the transducer-calibration data is unknown,
the Equivalent Input value for the factory-installed calibration resistor can be
approximated as follows, if the mV/V sensitivity rating of the transducer and the bridge
resistance are known.
X = ((25000 x Rb) / (K x Rc))
Where X = Equivalent Input (% of full scale)
Rb = Bridge Resistance (ohms)
K = Transducer sensitivity (mV/V, full scale)
Rc = Calibration Resistance (ohms, 30k installed or proper value
supplied with sensor)
Sample Calculation:
Assume that K = 3.000 mV/V for a 10,000 pound capacity load cell (F.S.) with a bridge
resistance of 350 ohms.
X = ((25,000 x 350) / (3.000 x 30,000)) = 97.22% F.S. = 9,722 lbs.
