Range
See OPERATING PRESSURE RANGE
Repeatability
The maximum change in output under fixed operating conditions over a specified period of time.
Resolution
The maximum change in pressure required to give a specified change in the output.
Response Time
The time required for the incremental change in the output to go from 10% to 90% of its final value
when subjected to a specified step change in pressure.
Room Conditions
Ambient environmental conditions under which sensors most commonly operate.
Sensing Element
That part of a sensor which responds directly to changes in input pressure.
Sensitivity
The change in output per unit change in pressure for a specified supply voltage or current.
Sensitivity Shift
A change in sensitivity resulting from an environmental change such as temperature.
Stability
The maximum difference in the output at any pressure in the operating pressure range when this
pressure is applied consecutively under the same conditions and from the same direction.
Storage Temperature Range
The range of temperature between minimum and maximum which can be applied without causing
the sensor to fail to meet the specified operating characteristics.
Strain Gauge
A sensing device providing a change in electrical resistance proportional to the level of applied
stress.
Supply Voltage (Current)
The voltage (current) applied to the positive and negative (ground) input terminals.
Temperature Coefficient of
Full Scale Span
The percent change in full scale span per unit change in temperature relative to the full scale span
at a specified temperature.
Temperature Coefficient of
Resistance
The percent change in the DC input impedance per unit change in temperature relative to the DC
input impedance at a specified temperature.
Temperature Error
The maximum change in output at any pressure in the operating pressure range when the tempera-
ture is changed over a specified temperature range.
Temperature Hysteresis
The difference in output at any temperature in the operating temperature range when the tempera-
ture is approached from the minimum operating temperature and when approached from the
maximum operating temperature with zero pressure applied.
Thermal Offset Shift
See TEMPERATURE COEFFICIENT OF OFFSET
Thermal Span Shift
See TEMPERATURE COEFFICIENT OF FULL SCALE SPAN
Thermal Zero Shift
See TEMPERATURE COEFFICIENT OF OFFSET
Thin Film
A technology using vacuum deposition of conductors and dielectric materials onto a substrate
(frequently silicon) to form an electrical circuit.
Vacuum
A perfect vacuum is the absence of gaseous fluid.
Zero Pressure Offset
The output at zero pressure (absolute or differential, depending on the device type) for a speci-
fied supply voltage or current.
