Measuring range: The measuring range describes the load range in which the guaranteed error limits must be observed.
Nominal load: The nominal load is the maximum load within the measuring range. Depending on the sensor, this can be a tensile or compressive load.
Accuracy class: The accuracy class indicates the largest individual error (in percent) related to the output signal of the sensor. For load cells, this is determined according to OIML R60. The characteristic value tolerance is not taken into account here.
Working load: The working load is the maximum load that the sensor can withstand beyond the nominal load without losing its specified properties. This range should only be used in exceptional cases.
Limit load: The limit load is the highest permissible load at which the sensor is not destroyed. However, the specified error limits no longer apply to this load.
Breaking load: The breaking load is the load at which the sensor is permanently damaged or destroyed.
Maximum dynamic load (according to DIN 50100): This is the maximum oscillation range of a sinusoidally changing force that the sensor can withstand at nominal load over 10^7 cycles without showing significant changes in its metrological properties.
Nominal measuring path: The nominal measuring path is the path that the outer load introduction points cover in the measuring direction when the nominal load is introduced.
Input resistance: The input resistance is the ohmic resistance between the connections for the supply voltage.
Output resistance: The output resistance is the ohmic resistance between the connections for the output voltage.
Bridge resistance: The bridge resistance is the total ohmic resistance of the measuring bridge.
Insulation resistance: The insulation resistance is the ohmic resistance between the connection cables and the sensor body.
Temperature coefficient of the characteristic value: This is the change in the actual characteristic value in relation to the nominal characteristic value with a temperature change of 10 K.
Temperature coefficient of the zero signal: The temperature coefficient of the zero signal indicates the Change in the output signal of an unloaded sensor with a temperature change of 10 K.
Reference temperature: The reference temperature is the ambient temperature to which the technical data of the sensor refers.
Nominal temperature range: The nominal temperature range is the temperature range in which the sensor maintains its technical data and error limits.
Operating temperature range: The operating temperature range is the temperature range in which the sensor can be operated without permanent changes to its measuring properties. However, the specified error limits no longer apply in this range.
Supply voltage: The supply voltage is the supply voltage required for error-free operation of the sensor.
Characteristic value: The characteristic value is the output signal at nominal load minus the preload signal.
Nominal characteristic value: The nominal characteristic value is the theoretically specified target value of the characteristic value.
Storage temperature range: The storage temperature range is the temperature range in which the sensor can be stored mechanically and electrically unloaded without permanent changes to its measuring properties occurring.
Composite error: The composite error Fcomb is half the distance c between the limits of the tolerance band that defines the characteristic curve in the measuring range with increasing and decreasing load. , based on the nominal value Cn. It is made up of the linearity error and the hysteresis error.
Fcomb = c / Cn
Creep error: The creep error is the maximum permissible change in the sensor's output signal over a certain time under constant load and stable ambient conditions.
Variability: The variability is a measure; for the relative standard deviation of the output signal, resulting from ten repeated measurements at two points on the characteristic curve, each with the same mechanical size and the same changes.
Protection class according to DIN VDE 0470 (replaces DIN 40050), EN 60529: The protection class of a housing is defined by the abbreviation IP and a two-digit code number that describes the contact, foreign body and water protection for electrical equipment.
Control: A control resistor in the sensor generates a signal that corresponds to the nominal value of the sensor. This reduces the need for recalibration and allows the zero point and nominal value to be checked before each measurement.
Minimum division / resolution: The minimum division or resolution is the smallest measurable subdivision of the step.
Zero signal: The zero signal is the output signal of the sensor in the unloaded state.
Zero return: The zero return is the maximum permissible change in the output signal of the sensor over a certain time after complete unloading under stable ambient conditions.
Fastening torque: The fastening torque is the prescribed tightening torque of the mounting screws for fixing the Sensors.
