022002X INTRODUCTION
Strain gauge-type transducers electrically measure physical quantities such as load and displacement. They operate by converting
measured physical quantities into mechanical stress, and then detecting that stress with a strain gauge. TML offers a number of
products according to the item and quantity measured. Since our products use strain gauges, they can be connected to all types of
strainmeters, such as Data Loggers and dynamic strainmeters, for taking measurements. This enables capabilities like automatic
multiple-point measurement as well as measurement via computer. Our strain gauge-type transducers offer a variety of features like
compact size, light weight and easy operation, high-precision measurements with excellent linearity and consistency, as well as
dynamic measurement capability that is available in many of our products. These features led to widespread use of our strain gauge
tranducers not only for testing and research, but for control in all types of industrial and civil engineering fields as well. For more
details on civil engineering transducrs, be sure to refer to our catalog entitled Civil Engineering Transducers provided separately.

Transducer bridge circuit and connector alignment
Bridge circuit inside and wiring system are given as follows, but not
applicable to some products. When connector plug is required, specify it
on order to install the plug to the transducer cable.
Transducer Input/Output resistance
Rated output and strain value
The output (rated output) the transducer, one of capacity specifications, is
expressed as mV/V. mV/V is the output voltage when a maximum load is
applied to a transducer. It shows the output voltage generated when 1V
is applied.
Example:
1.5mV/V means that 1.5mV is output when a load below the transducer's
full capacity is applied while 1V is applied to it at the same time. If 2V is
applied to it (bridge power on a strain measuring instrument):
1.5mV/V�2V3mV
Therefore, if the gauge factor is 2.00 (coefficient set at 1.000) the output
voltage of a transducer is 3mV and the value to be shown on a strain
measuring instrument can be calculated by the following expression,
which is formulated based on the voltage-to-strain relational expression;
eK where,
eOutput voltage (V) of a transducer
EExcitation voltage (V)
KGauge factor of a strain measuring instrument
Reading on a strain measuring instrument
With K, E and e defined as 2.00, 2V, and 3mV, respectively, 3mV is
equal to 0.003V and therefore

Decreased sensitivity due to a long cable used
to connect to a transducer
Constant-voltage and constant-current power systems are used to provide
a strain measuring instrument with the bridge excitation (voltage to be
applied to a transducer). If a strain measuring instrument designed for
use with the constant-voltage system is used and if a cable (including the
attached cable that comes with the transducer unit) must be further
lengthened, the sensitivity or the rated output of a transducer deteriorates
due to wire resistance. In this case, the rated output (
m
) must be
adjusted to obtain a new rated output (
s
) based on the length and
thickness of the longer new cable to be installed by using the following
eqauation. s m

Strain instruments with constant voltage and
Constant current method
Constant voltage type
The bridge power supply in our rated voltage-type strainmeter ensures a
constant voltage regardless of the input resistance of any connected
transducer. Even so, the sensitivity of the transducer will drop due to
wire resistance in the connecting cable if the transducer cable is
extended.
Constant current type
Current form the bridge power supply to the transducer remains constant
with our constant current-type strainmeters regardless of the input
resistance of the transducer or the length of the cable (wire resistance).
Therefore, the sensitivity of the transducer will not drop due to wire
resistance in the cable if the transducer cable is extended. However,
there is a limit on the input resistance of the transducer. 3
Transducer terminology
Capacity

specfications.
Rated Output (RO)
Output at the rated load minums output under no-load conditions.
Rated outptu is expressed per volt applied to the transducer (mV/V).
Non-linearity

and the ra
