Transducer Terminology

Capacity
Maximum load that a transducer can measure and still maintain specifications
Rated Output = RO
Output at the rated load minus output under no-load conditions. Rated output is expressed per volt applied to the transducer (mV/V).
Non-linearity
Maximum difference of the transducer's output from a line connecting the calibration curve origin and the rated load point with increasing loads. Non-linearity is expressed as a percentage of rated output (%RO).
 
non-linearity
Hysteresis
Maximum difference between transducer output with increasing and decreasing loads. Hysteresis is expressed as a percentage of rated output (%RO).
 
hysteresis
Repeatability
Maximum difference in output when the same rated load is measured repeatedly under identical load and environmental conditions. Repeatability is expressed as a percentage of rated output (%RO).
Temperature Effect on Zero
Transducer output due to changes in ambient temperature. Temperature effect on zero expresses change per degree of ambient temperature as a percentage of rated output (%RO/℃).
Temperature Effect on Span
Rate of change in load output due to changes in ambient temperature. Temperature effect on span is expressed per degree of ambient temperature (%/℃).
Compensated Temperature Range
Range of temperatures compensated for temperature effect on zero and span. (℃).
Temperature Range
Range of temperatures that can be applied continuously without causing permanent destructive change to the transducer (℃).
Overload
Load that can be applied continuously without causing permanent change exceeding specifications (%).
Ultimate Overload Rating
Maximum load that can be applied continuously without causing permanent destructive change mechanically (%).
Recommended Exciting Voltage
Voltage that can be applied to the transducer and still maintain the specifications (V).
Allowable Exciting Voltage
Maximum voltage that can be applied continuously to the transducer without causing permanent destructive damage (V).
Zero balance
Output strain while unloaded (x10-6 strain)
Frequency Response
Maximum frequency at which the transducer can output within a specified range using a sine wave load (Hz).
Natural Frequency
Frequency under no-load conditions at which a transducer oscillates freely (Hz).
Allowable Bending Moment
Maximum bending moment that can be applied continuously to the transducer without causing permananet destructive damage (kN·m).
Sensitivity
Transducer output with a fixed load. Sensitivity expresses strainmeter output per millimeter (x 10-6 strain/mm) when the strainmeter coefficient on the displacement transducer is set at 1.000 (2.00 gauge factor fixed).
Gauge Length
Distance between two points used to measure displacement or strain.
Spring Force
Approximate force required to displace capacity on the displacement tansducer (N).
Input / Output Resistance
Resistance between input and output terminals measured under no-load conditions with input and output terminals disconnected (Ω).
Input / Output Cable
Cable that cannot be disconnected from the transducer.
Supplied Cable
Standard cable accessory that can be disconnected from the transducer.
Weight
Approximate weight of the main unit minus I/O cable and cable accessories.(g,kg)
About IP ratings
A classification system rates how well enclosures and package for electrical components seal against intrusion by foreign materials such as dust and moisture. It conforms to JIS C 0902, or IEC 60529, and entails various levels of ingress protection afforded against solid objects and water.
