Submersible Pressure Transmitter for Level and Depth Measurement
-------------------------------------------------------
Manufacturer: Omega(USA)
Model: PX78MV
Introduction:
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.
