OMEGA’s PXM79 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 15 m (50 foot) vented cable, longer lengths available, provides an atmospheric reference. Each transducer is shipped with a moisture trap that prevents moisture from entering the vent tube.
The PXM79 is also available in metric configurations, with models from 0-70 to 0-700 mbar pressure ranges. Please see the PX79 for complete details, or contact our Pressure department for more information..
