The Siemens Division Industry Automation has added a PVDF (Polyvinylidene Fluoride) nose cone as an option to the non-contacting ST-H ultrasonic level transducer for liquids.

This new material type improves the chemical compatibility of the ST-H transducer, offering more options for wet well, chemical storage, and process vessel applications.

When paired with a Siemens ultrasonic controller the ST-H transducer effectively measures the level of liquids in applications up to ten meters distance (33 feet) in conditions from -40 to +73 degrees Celsius (-40 to 164 degrees Fahrenheit). The transducer design includes both a 1 inch and 2 inch integral process connection. This allows easy mounting on varied vessels and wells. When installed using the 2 inch mounting threads, the only wetted parts are PVDF, providing excellent chemical immunity in corrosive atmospheres.

The ST-H transducer is impervious to dust, moisture, corrosion, vibration, flooding and temperature extremes. The non-contacting design virtually eliminates the nuisance, danger and expense of cleaning, adjusting and repair associated with contacting devices.
