Step response time
5)
≤ 5 s (with damping 1 s)
Ambient conditions
Ambient, storage and transport tempera-
ture
-40 … +60 °C (-40 … +140 °F)
Process conditions
For the process conditions, please also note the specifications on the type label. The lower value
always applies.

2 x cable gland M20 x 1.5 (cable: ø 6 … 12 mm), 4 x
blind plug M20 x 1.5
Included: 1 x cable gland M20 x 1.5
5)
Time span after a sudden measuring distance change by max. 0.5 m in liquid applications, max 2 m with bulk
solids applications, until the output signal has taken for the first time 90 % of the final value (IEC 61298-2).
6)
Tested according to the guidelines of German Lloyd, GL directive 2.
