OMEGA’s PX78 Series transmitter is a submersible transducer suitable for liquid level and depth measurement. Its all stainless steel, hermetically sealed housing make it suitable for immersion in most industrial liquids and oils. A 3 m (10 ft) vented cable (longer lengths available) provides an atmospheric pressure reference.
The PX78 is also available in metric configurations, with models from 0-270 mbar to 0-1 bar pressure ranges. Please see the PXM78 for complete details, or contact our Pressure department for more information..
