Lateral force effect

Is the relative influence on the signal caused by a lateral force put on the sensor.

Torque effect

Is the relative influence on the signal caused by a torque put on the sensor.

Rated displacement

The deformation distance under nominal load which is measured at the surface of the Transducer.

Permissive oscillation stress

Range of force oscillation which is allowed to be put on the sensor (example: 20% to 100% FSO).


If the sensor unintentionally responds to a measurand. For instance a force crosswise to the measurand force. Cross talk is noted in percent if the compared units are the same (example: N/N). Otherwise units get noted as a break (example: Nm/N).

Storage temperature

The temperature range which shouldn't be exceeded at the storage.

Storage life

The minimum of time, where a sensor can be stored under specific conditions without losing it's given conditions.

Continous rating

Given operating conditions which can be applicated for a specified uninterrupted length of time.

Cycling life

The guaranteed amount of measuring cycles where a sensor keeps it's performance within defined borders.

Operating life

The guaranteed span of time where a sensor keeps its performance within defined borders.

Strain error

An error caused by a strain in the mounting- surface of the sensor.

Deformation sensitivity

Error caused by mounting the sensor.

Output impedance

The impedance of a sensor and it's associated external circiutry.

Insulation resistance

The electrical resistance between two phases of a sensor under DC and mentioned temperature.

Rise time

The time elapsed until the output signal can follow a stepwise change of the measurant from 10 to 90%. Because of the small amount of time elapsed during the signal rises the time can be approximated by dividing the period of the ringing frequency by 4.


The part of the output signal which exceeds the signal after the ringing period.

Ringing period

The time elapsed untill the ringing frequency's amplitude does not exceed 10% of the output value.

Ringing frequency

The frequency occuring in the sensor output after a step change of the measurant.

Fundamental resonant frequency

The measurand frequency leading to a maximum output signal.

Natural frequency

The frequency of a fully mounted sensor which is oscillating free.

Frequency response

The dependence of the output/measurand amplitude and it's phase difference at a sinusoidally varying measurand.

Dynamic characteristics

Characteristics of a sensor which depend on a change of the measurand within a certain time.


Is the ability of a sensor to deliver reproduceable output signals. That means that under same conditions at the same measurant(s) the sensor should give the same output (in % FSO).


The ability of a sensor to keep the validity of the calibration characteristics over a specified period of time within specified limits.


An unrequested change of the output signal which is not in relation to a change of the measurand. (This effect is unusual for quartz and other monocrystals but it occurs at ceramics moreoften).

Vibration error

The maximum change of the output signal at any measurand value within the measuring range caused by a vibration of specified amplitudes and frequencies along a specific axis (in %FSO).

Acceleration error

The maximum change of the output signal at any measurand value within the measuring range caused by an acceleration along a specific axis.

Temperature gradient error

A temporary change of the output signal at a constant measurand value because of a changing sensor temperature (fluid or ambient).

Temperature error

The highest change of the output signal from room temperature to maximum operating temperature.

Thermal zero shift

A change of the output zero due to a change of temperature.

Zero shift

A change of the output zero over a period of time.

Measurand temperature range

The range of measurand temperatures where the sensor is operating at given conditions limited by the minimum and maximum measurant temperature.

Operating temperature range

The temperature range which does not destroy the sensor but specifications may be exceeded.

Rated temperature range

The range of temperature where the sensor keeps its conditions.

Reference straight line

An approximated line in the measurant- output- diagram where the maximum output deviations from the line are equal in positive and negative signal direction. In practice the best straight line has a forced 0 wich means that a 0 at the measurant is a 0 at the output signal.

Relative linearity error

Difference between highest and lowest deviation of the "best straight line" with forced zero at the output signal during a calibration cycle (in % of the FSO).

Relative reversibility error

The maximum deviation of the output signal at an increasing and decreasing measurand in % of the full scale output (FSO).


The smallest change of the measurand leading to a change of the output signal.


The ratio between measurand and output signal (example: pC/N or pC/bar).

Calibration record

Is a plot of the measurand of the calibration cycle and the related output signal.

Calibration cycle

Is a known run of measurands put on the sensor.


Is a test used to determine the relationship between output and input parameters.


The highest measurand where the sensor can work at given performance.


Is the difference between minimal and maximal range.


The purposed area of the measurand which the sensor is covering named by its maximum and minimum (example: -100°C/+100°C).

Sensing element

Part of the sensor reacting directly to the measurand.


An electrical quantity produced by the sensor depending on the measurand.

Sensor (or transducer)

An object which generates a useful signal output at a specific measurand.


A property, quantity or condition which is measured by the sensor.

Force limit

Any force exceeding this limit leads to lasting changes of the sensor specifications.

Maximum operation force

Maximum force where the sensor works at given conditions.

Rated force

Force wich the sensor is designed for. In this range, the manufacturer's specifications are met.


Full scale output.

Breaking force

The pressure where parts of the sensor (case or sensing element) get rupted.
