Submersible Pressure Transmitters

PX79 Series has been discontinued. Please see High Accuracy Submersible Pressure Transmitter PX633 series as possible alternative or contact our sales department.
OMEGA’s PX79 Series transmitter is a submersible low pressure transducer suitable for liquid level and depth measurement. Its stainless steel housing and Inconel diaphragm makes it suitable for immersion in most industrial fluids. A 50 foot (15.2m) vented cable, longer lengths available, provides an atmospheric reference.
The PX79 is also available in metric configurations, with models from 0-70 to 0-700 mbar pressure ranges. Please see the PXM79 for complete details, or contact our Pressure department for more information..
