Glossary of Terms (continued)

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.
