Degree of protection

IP (Ingress Protection) class ratings classify the level that a LVDT-sensor is protected against infiltration by foreign materials such as water or dust. The types of protection are differentiated according to the degree of protection and are classified according to DIN 40 050.


Indication of the measuring range designed for the LVDT, in which the technical data can be observed.


Excitation frequency

Frequency at which a forced oscillation excites the system and feeds the primary winding of the transducer.


Impact resistance

Capacity to withstand mechanical impacts (measured as a multiple of the gravitational acceleration g) according to DIN IEC68T2-2.


Linearity deviation

Deviation of the LVDT output signal from the statistically best-fit straight line between input variable (e.g. distance to an object) and output signal of a sensor (e.g. voltage output) related to the core displacement within an LVDT's nominal linear range. It is given as a percentage of the measuring range end value (FS or Full Scale).


Output impedance

AC resistance that the output of a circuit opposes to the electric current.

Output signal

The signal applied to the output as a function of travel.


Rated temperature range

The range of ambient temperature in which the LVDT-sensor can be operated without permanent change to its performance data. Full functionality can only be guaranteed if the sensor is operated within the specified temperature ranges.



Change in the value of the output variable of a measuring instrument related to the causative change in the value of the input variable as a function of the excitation voltage. Data in mV/V/mm.

Storage temperature range

Range of the ambient temperature in which the mechanically and electrically unstressed displacement sensor may be stored without permanent significant changes in the metrological properties of the sensor being detectable when using the sensor again within the rated temperature range. If the sensor is stored at temperatures within the storage temperature range, the values specified in the data sheet do not change.


Temperature coeffient

Relative change of the output signal as a function of temperature.


Vibration resistance

Specification at which acceleration or amplitude in a defined frequency range no malfunctions or damage occur. Vibration resistance exists when the exposed vibrations are withstood without damage.


Weight (with cable/plug)

Mass of the inductive displacement sensor, optionally with connector.

Weight core

Mass of the core.
