DM330 Magnetostrictive Level Transmitter


The DM330 Series is a two wire, 4-20 mA output level transmitter that is not affected by changes in electrical characteristics. Suitable for I.S. installations with Class I Div. 1, Zone 0 approvals from FM, CSA and ATEX.
The Drexelbrook DM330 magnetostrictive level transmitter is a two wire loop powered intrinsically safe sensor with a configurable 4 -20 mA span.

This level transmitter uses proven machine tool positioning accuracy combined with a process compatible float to offer a liquid level, and interface measurement system for the process industry.

It comes in a patented low clearance design with all of the sensor’s electronics integrated in a 5/8” diameter sensing tube eliminating the electronics enclosure at the top of the sensor. Not only does this result in reduced cost it also offers its user greater options for insertion and mounting.

The DM330 is available in two models.
The rigid 316SS model offers a choice of a mini-connector or an optional housing including terminal connectors with zero and span adjustments.

The flexible, patented PVDF model provides a wide range of mounting options along with cost effective, high accuracy inventory monitoring in tanks up to 40 ft.

Both models are easy to install, require a minimal maintenance and no calibration.
