Page 7: Section 1: Introduction
Introduction Section 1: Introduction Product Description The AMETEK Drexelbrook DM330 Series Magnetostrictive Level System is an integral assembly that measures linear motion or liquid level using magnetostrictive technology. A single level output is provided with configurable 4 and 20mA points in an intrinsically safe, standard two wired loop-powered configuration. -
Page 8: Technology
DM330 Series - Magnetostrictive Level System User's Manual Technology In a magnetostrictive level sensor a current pulse is sent down a wave guide made of a special nickel alloy wire designed to enhance magnetostrictive properties. A permanent magnet within a float is used to indicate the position or level being measured. -

Installation Section 2: Installation IMPORTANT Be sure to read & understand all of the Installation Instructions before beginning the procedure! Unpacking Carefully remove the contents of the shipping carton and check each item against the packing list before destroying any packing materials. - Page 14 DM330 Series - Magnetostrictive Level System User's Manual 2.1.1 Storage (Continued) DO NOT remove from crate and store as shown below, the PDVF tubing may bend and become damaged under is own weight. Damage that occurs in storage is not covered under manufacturers system warranty.

Page 15: Mounting Conditions
Probes are sealed at the factory and have electronic circuits inside. Do not attempt to open probe or weld the tube. • DM330 Series level system is designed for industrial applications, but should be mounted in a location as free as possible from vibration, corrosive atmospheres, or any possibility of mechanical damage. - Page 16 DM330 Series - Magnetostrictive Level System User's Manual Mounting Conditions (Continued) 3/4" NPT 7/8" - 16 UNS-2A Mini-connector on 316SS version 3/4" NPT Probe 5/8 Flexible PVDF Tubing 3/4" NPT Adjustable Compression Fitting Reducing Bushing Optional Flange Probe Type Span Range 316SS 8 in.

Page 17: Mounting Considerations
Installation Mounting Considerations Mounting considerations may vary (Flanges, Compression Fitting, etc.) depending on the application. For underground tanks, the probe is generally mounted in the riser, resting on the bottom of the tank. Spacers are used to hold the sensor in the riser and a cable is suspended from the tank cap. - Page 18 DM330 Series - Magnetostrictive Level System User's Manual 2.4.1 Sizing of Stainless Steel Probe Insertion Length is: Actual length from mounting point to bottom of tank. Overall length of probe is: Insertion Length plus 2 inches (51mm) for Flange mounted probe, and Insertion Length plus 6 inches (152mm) for Compression Fitting mounted probe.
- Page 19 Installation 2.4.2 Assembly of Stainless Steel Probe 1. Standard SS Float Kit should contain a 2 inch 316 stainless steel float, spacer and retainer to hold float on to probe. The standard retainer is a 316 SS "E-Clip". Optionally, if the probe is to rest on the bottom of a metal tank, an ECTFE End-Cap may be supplied With either, a spacer is required to insure SS float is positioned in active area of span.

Page 20: Flexible Polyvinylidene Fluoride (Pvdf) Probe Mounting
DM330 Series - Magnetostrictive Level System User's Manual 2.4.3 Insertion of Stainless Steel Probe CAUTION: Do not allow float to drop suddenly since it can damage retainer at end of probe. 1. Insert bottom end of probe into tank. 2. Thread bushing into tank or flange. Bolt flange into position. - Page 21 Installation 2.5.1 Sizing of PVDF Probe Insertion Length: The actual height of the tank from the mounting point to the bottom of the tank. Clearance: The distance from the bottom of the tank required for probe expansion at higher temperatures. Dead Band: Inactive area at the bottom of the probe.
- Page 22 DM330 Series - Magnetostrictive Level System User's Manual 2.5.2 Assembly of PVDF Probe CAUTION! Do NOT unwind coiled probe until actually feeding into vessel! Damage will occur. Assembly of a PVDF probe is almost the same as 316 SS probe, except that a weight is used for probes longer than 16 feet (3.66m) long to keep the probe perpendicular.
- Page 23 Installation 2.5.3 Before Insertion of PVDF Probe At this point, if probe span is to be set outside the vessel, then go to Section 2-9 Setting Span before continuing... BUT READ THIS FIRST! If necessary to set the span outside of the tank, take extra precaution to avoid damaging the flexible probe.
- Page 24 DM330 Series - Magnetostrictive Level System User's Manual 2.5.4 Insertion of PVDF Probe Longer probes are coiled and have numbered tie wraps. When installing probe, cutting tie wraps in sequence helps to prevent the installer from accidentally twisting the probe.

Page 26: Wiring
DM330 Series - Magnetostrictive Level System User's Manual Wiring The AMETEK Drexelbrook Magnetostrictive Level sensor uses solid state surface mount electronics within the probe itself, providing a two-wire 4-20 mA output externally powered from the loop itself. Operating voltage is from 13.5 to 30 Vdc. - Page 27 Installation Wiring (Continued) Hazardous Area Non-Hazardous Area Group IIA, IIB, Zones 0, 1, or 2 (Red, + Loop) Safety + Loop Barrier (White, Program*) (Black, - Loop) - Loop (Shield, Earth Ground) * Reference Section 6: Control Drawings 420-0004-233-CD for installation wiring.
- Page 28 DM330 Series - Magnetostrictive Level System User's Manual 2.7.2 Intrinsically Safe Barriers Select either a single or dual channel barrier. Single channel barrier can only be used if meter (resistive load) is placed in the positive end of loop and meter has a differential input.

Operation Section 3: Operation The Magnetostrictive Level System is used for accurate and repeatable measurement of linear motion and liquid level. All of the sensor’s electronics are integrated into the probe. Magnetostrictive technology uses a float with an embedded magnet that travels along the 5/8-inch diameter tube. Inside the tube is a wire that is pulsed with a current that travels down the wire. - Page 34 Section 4...
