C
Cut-off frequency / Output
Frequency at which the amplitude is attenuated by 3dB.
D
Degree of protection
IP (ingress protection) ratings classify the level that a sensor is protected against infiltration by foreign materials such as water or dust. Protection types are classified according to DIN 40 050.
DMS-Sensitivity
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.
I
Insulation resistance
The insulation resistance, measured between short-circuited electrical connecting leads and the housing or process connection, contains at least an indication of the test voltage and optionally the test time.
N
Noise / residual ripple
RMS value of the noise of the output signal in the specified frequency range.
O
Ouput load
Minimum input resistance of the connected measuring system.
Output signal
The signal applied to the output as a function of travel.
R
Rated temperature range
Range of the ambient temperature in which the signal conditionier complies with the error limits for the temperature-dependent technical data.
Relative linearity deviation
Deviation from the statistically best-fit straight line.
S
Setting range offset
The output signal of a sensor is generally not equal to zero in the unloaded state. This zero offset is called offset.
An offset can also be caused by a preload, by temperature changes or because of internal electronics.
With strain gauge resistor bridges, the resistors used are not exactly the same, resulting in a small (but constant) offset due to the system.
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.
Supply voltage
Voltage with which (strain gauge) sensors are supplied, also called supply voltage.
T
Temperature effect on zero signal
Variation of the zero signal of the sgnal conditioner in relation to the rated characteristic value, due to variation of the ambient temperature, Ti by 10 K, within a defined temperature range after steady states free of gradients have been adjusted.
(The greatest value of TK0 and the temperature range are to be stated.)
