Update time
7)
minimum 1 second, depending on settings for Re‐
sponse Rate (2.4.1.) and LCD Fast Mode (4.9.)
Influence of ambient temperature < 0.003%/K (average over full temperature range, ref‐
erenced to maximum range)
Long-term stability <0.1 % over 60 months

Memory non-volatile EEPROM
no battery required
1)
The statistical accuracy is typically 3 mm (0.12") 90% of the time, when tested in accordance
with IEC 60770-1.
2)
Under severe EMI/EMC environments per IEC 61326-1 or NAMUR NE21, the device error
may increase to a maximum of 10 mm (0.4").
3)
For 2" threaded PVDF, Flanged encapsulated antennas and Hygienic encapsulated
antennas, the maximum measured error <500 mm from the sensor reference point =25 mm
(1").
4)
From sensor reference point: see Dimensions (Page 175).
5)
20 m (65.6 ft) possible in a stillpipe/bypass
6)
Minimum range is antenna length + 50 mm (2"). See Dimension drawings (Page 175).
7)
Reference conditions: Response Rate (2.4.1.) set to FAST, LCD Fast Mode (4.9.) set to ON.
8)
For 1.5" (40 mm) antenna, 2" (50 mm) threaded PVDF antenna, 2"/DN50/50A flanged
encapsulated antenna, and 2" ISO 2852, DN50 DIN 11864-1/2/3, DN50 DIN11851,
Tuchenhagen Types F and N hygienic encapsulated antenna the minimum dK is limited to 3
unless a stillpipe is used.
