Tolerances at T

Nominal characteristic value Relative deviation in % related to the measuring range
final value
Typical Maximum
Unipolar 1 mV/V, 2 mV/V, 3 mV/V, 4 mV/V ±0.1% ±0.3%
Bipolar ±1 mV/V, ±2 mV/V, ±3 mV/V, ±4 mV/V ±0.2% ±0.6%
The typical values contain the typical offset error, gain error and linearity error in the respective configuration related to the positive measuring range up to
100% of the nominal characteristic value. This data is valid for nominal operation (preferred mounting position, U
S
= 24 V) with16-sample average value filter.
The maximum tolerance values represent the worst case measurement inaccuracy. Besides the maximum offset error, the gain error and the linearity error,
the maximum tolerance values also comprise the longtime drift as well as the maximum tolerances of the test and calibration equipment.
Please also observe the values for temperature drift and the tolerances influenced by EMI.
This data is valid for at least twelve months.
Additional tolerances influenced by electromagnetic fields
Type of electromagnetic interference Relative deviation in % related to the measuring range
final value
Electromagnetic fields, field strength 10 V/m in acc. with EN 61000-4-3 < ±0.7%
Conducted interference, Class 3 (10 V test voltage)
according to EN 61000-4-6
< ±0.2%
Fast transients (burst) up to an interference voltage of ±2.2 kV
according to EN 61000-4-4
< ±0.3%
You can minimize the interference by connecting the sensor cable shield to the DIN rail in front of the terminal via a shield connection clamp
(see "Accessories" on page 3).

The typical values contain the typical offset value and gain value in the respective configuration in the temperature range from -25°C up to +55°C related to
the positive measuring range up to 100% of the nominal characteristic value. This data is valid for nominal operation (preferred mounting position, U
S

with16-sample average value filter.
The maximum tolerance values represent the worst case measurement inaccuracy. Besides the maximum offset drift and gain drift, they also comprise the
longtime drift as well as the maximum tolerances of the test and calibration equipment in the temperature range from -25°C up to +55°C.
