VEGA VEGAPULS 45 VBUS - Manual (Page 84)

84 VEGAPULS 42, 44 and 45 – VBUS
Technical data
Measured value display (optional)
Liquid-crystal indication
- in the sensor scalable output of measured values as graph
and as number
- in the external indicating instrument scalable output of measured values as graph
powered by the sensor and as number. Measured value display can be
mounted up to 25 m away from the sensor
Adjustment
- PC and adjustment software VEGA Visual Operating
- adjustment module MINICOM
- VEGA signal conditioning instrument
Accuracy 1) (typical value under reference conditions, all statements relate to the nominal
measuring range, for type 45 relating to a measuring range of 4 m)
Characteristics linear
Accuracy (deviation in characteristics
incl. linearity, repeatability and
hysteresis determined by the
limit point method)
< 0.05 %
Average temperature coefficient
of the zero signal 0.06 %/10 °K
Resolution generally max. 1 mm
Resolution of the output signal 0.005 % or 1 mm
