Ultrasonic Transducer Measures Liquid Levels In Corrosive Atmospheres
Siemens Energy & Automation, Inc. announced the addition of a Polyvinylidene Fluoride (PVDF) nose cone as an option to the non-contacting ST-H ultrasonic level transducer for liquids. This new PVDF material is said to improve the chemical compatibility of the ST-H transducer, offering more options for wet well, chemical storage and process vessel applications.
The ST-H transducer is impervious to dust, moisture, corrosion, vibration, flooding and extreme temperature. The non-contacting design eliminates the inconvenience, danger and expense of cleaning, adjusting and repair associated with contacting devices, according to the company.
When paired with a Siemens ultrasonic controller, the ST-H transducer effectively measures the level of liquids in applications up to a distance of 33 feet and in conditions from -40 to 164 degrees Fahrenheit. The transducer design includes both a 1-inch and 2-inch integral process connection that enable 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.
