6. Con nectio n
6.1 Connect the transducer to a measuring instrument.
6. 2 When using a measuring instrument other than KYOWA, connector
plug as follows.
When connected the attached cable, shield wire is connected to the
case.
6. 3
Heat run for 5 minutes or longer before starting the measurement.
7. Co n v ers i o n
7. 1 Use the calibration constant described in the test data sheet to
convert a reading into a pressure value.
7 . 2
When a strain amplifier is in use, output reads in ×10-6 equivalent
strain. Find a pressure value corresponding to ×10-6 strain. Then,
obtain a pressure value through multiplication using the following
equation.
Pressure (Pa) = Strain amplifier’s output (×10-6 strain)
x Calibration constant (Pa
/
1×10-6 strain)
7. 3 When using an amplifier of other type or a recorder, first find the exact
bridge exciting voltage applied. Second, find the pressure value that
corresponds to 1(μV) output voltage against 1(V) bridge excitation
voltage. Then, obtain the pressure value through multiplication using
the following equation.
Pressure (Pa) =
Bridge output voltage (μV) ×Calibration constant (Pa
/
1μV/V)
Bridge excitation voltage (V)
Sensitivity Decrease due to Cable Extension
If a strain-gage transducer is connected to a signal conditioner, digital
indicator or strain amplifier via extension cable, we will not ignore the
sensitivity decrease due to the extension cable resistance which lowers
the voltage applied to the transducer.
The rated output with lowered sensitivity is obtained from the following
equation:

8. Storage and inspection
8. 1 Avoid water, oil, dust, etc. on the connector.
8. 2 Recommend calibrate the product once a year or so. (Contact your
KYOWA representative.)
8. 3 If suspicious outputs have occurred, check the input resistance,
output resistance and insulation resistance. Provided that the
connector operates properly and that the insulation resistance
between the mainframe and conductors is below 100MΩ, the cause
may be failure.
In this case, contact your KYOWA representative.
Ca u tio n
To measure insulation resistance, apply a voltage lower than 50V to
the insulation resistance tester.
