Technical data

10.1

Accuracy

The specifications are typical values at 24 V DC and room
temperature, with a nominal length of 500 mm in
conjunction with the BTL-S-3112-4Z float.
The BTL is fully operational immediately, with full accuracy
after warm-up.
For special versions, other technical data may
apply.
Special versions are indicated by the suffix -SA
on the part label.

Certain production processes require e.g. sterilization at 120 °C...130 °C
for 0.5...1 hours (see Tab. 11-1).
4) A prerequisite is that no current can flow between GND and 0 V in the
event of polarity reversal.
