7.1 Accuracy
The specifications are typical values at DC 24 V and room
temperature, with a nominal length of 500 mm in
conjunction with the BTL-P-1013-4R, BTL-P-1013-4S or
BTL-P-1012-4R magnet or with the BTL2-S-6216-8P-Ex,
BTL2-S-5113-4K-Ex, BTL2-S-4414-4Z-Ex or
BTL2-S-4414-4Z01-Ex 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.

1) Nominal length = 500 mm, magnet in the middle of the measuring range
2) Individual specifications as per Balluff factory standard
3) Resonant frequencies excluded
4) To maintain the IP68 rating, ensure that the connection at the conduit
opening also meets this standard. Thread sealant should be used on the
conduit opening to ensure protection against moisture ingress. Take
measures to prevent the possibility of internal condensation at the
conduit opening from entering the BTL.
5) Number dependent on nominal length
Ensure power is limited to ≤ 5 W!
