OMEGA’s PX78 pressure
transducer is fully submersible,
designed for liquid level and depth
measurement. Its all stainless steel
hermetically sealed housing makes
it suitable for immersion in most
industrial liquids and oils. A
standard 15 m (50') vented cable
(longer lengths available) provides
an atmospheric pressure reference.
With a 5000 Ω bridge, the PX78
is designed to work with the
DMD-16 and DMD-17 in-line
amplifiers for long-distance
transmission of the signal.
