OMEGA’s PX78/PXM78 are
submersible transmitter suitable for
liquid level and depth measurement.
Their all stainless steel, hermetically
sealed housing makes them
suitable for immersion in most
industrial liquids and oils. A 15 m
(50') vented cable (longer lengths
available) provides an atmospheric
pressure reference.
