Metal Particle Detector The Metal Particle Detector switch from AMOT can detect and alert equipment operations of the presence of metal particles in non- conductive fluid lubrication systems (lube oil, Typical applications Developed for use in manual and automatic control systems: • Reciprocating equipment - diesel engines • Rotating equipment - steam turbines - transmissions and gear boxes • Unique grid sensing technology - detects metal particles and metal chips - detects all conductive metal particles (including non magnetic metal particles) • Provides early warning of impending failure - reduced operating costs - corrective maintenance can be scheduled to minimize costly downtime - prevents unnecessary repairs and replacement of expensive parts • Dual seal with weep hole construction - meets National Electric Code UL Class 1 Division 1, Groups A, B, C & D

Metal Particle Detector - MPD Installation For in depth installation instructions, refer to AMOT Form No. 1248 and Drawing No. 10956. Installation of the MPD is accomplished in four (4) steps: 1. Locating where the MPD will be mounted. The MPD must be located in a side stream of the lube oil / fluid system, after the pump but before the filter. (Refer to Figure 1). 2. Mounting the MPD. Mount the MPD with the grid in a horizontal position. It does not matter which process port is the IN port so long as the flow through the MPD is from top to bottom and the grid is on a horizontal plane. Two...

Activation of the MPD switch occurs when metal particles bridge the gaps on its electrical grid and complete a normally open (N.O.) electrical circuit to drive an alarm or shutdown relay (refer to Figure 2). For installation refer to work instructions log...

Metal Particle Detector - MPD Service & Maintenance Refer to Figure 3, cross sectional. Prior to servicing or maintaining the MPD: Make sure all electricity is disconnected from the MPD. Ensure all process pressure is relieved from the grid compartment before removing the MPD’s end cap (block valve closed, bleed valve open). AMOT MPD requires minimal maintenance. Recommended maintenance would include removal and replacement of the MPD’s End Cap O-Rings (23 ), Grid O-Ring Seal (8), and Grid Board ( 2). Inspection of the aforementioned components should take place during the equipment’s...
