DATA SHEET DM330S Series Magnetostrictive Liquid Level Sensor for the Food, Dairy, and Beverage Industry 3A Authorization • Authorized by the 3A Sanitary Standards Council for level applications in the food, dairy, and beverage industries. Easy Installation • No calibration needed • Program zero & span in the field • Set upper and lower limits on bench prior to installation. High Accuracy • 0.1% accuracy full scale over 4-20mA span. • 0.014" resolution. Minimal Maintenance • Unique diagnostic output provides float position beyond set span, beyond active range, as well as loss of float. Patented Low Clearance Design • Electronics all within 5/8" diameter sensor allows wider mounting options at less cost. Intrinsically Safe • Certified for Class I Div 1, Zone 0, Zone 1 Hazardous Locations Description The AMETEK Drexelbrook DM330S Magnetostrictive Level Measurement System takes field proven sensing technology and incorporates intrinsic safety with a field programmable zero and span. Packaging is our patented low clearance design, making the DM330S ideal for level monitoring in a variety of liquids and tank designs. The rigid 316 stainless steel sensors are available with 180 grit for food service or 240 grit finish for higher grade sanitary applications. They are also offered with a mini-connector or an optional housing which includes terminal connectors with zero and span adjustments. All have totally welded and polished construction. All of the sensor's electronics are integrated within the 5/8" diameter sensing tube. This breakthrough in package design eliminates the electronics enclosure at the top of the sensor, which reduces cost and offers greater options for insertion and mounting. The DM330S is a two wire loop powered intrinsically safe sensor with a configurable 4-20 mA span. A variety of floats and mounting accessories are available to fit virtually any application.
