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.
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.
Patented Flexible Probe
• PVDF version provides cost effective, high accuracy inventory monitoring up to 40 feet with flexibility and reduced weight for easier installation.
Intrinsically Safe
• FM, ATEX, CSA, CE, 3A Approved

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 DM330 ideal for level monitoring in a variety of liquids and tank designs.

 Two Variations - Sensors are available in rigid 316SS or flexible PVDF designs.  The stainless steel version has a choice of a mini-connector or an optional housing which includes terminal connectors with zero and span adjustments. All offer totally welded construction.

The flexible (PVDF) version offers with a variety of mounting options and provides cost effective, high accuracy inventory monitoring in tanks up to 40 feet.

 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 DM330 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.  Included is a sanitary stainless steel version.  Contact the factory to match your needs today.
