MPD - Metal Particle Detector

Features

● UNIQUE GRID SENSING TECHNOLOGY
~ Detects metal particles, metal chips, and metal dust.
~ Detects all conductive metal par- ticles (including non magnetic metal particles).
~ No moving parts.

● DUAL SEAL WITH WEEP HOLE CON-STRUCTION
~ Meets API 614
~ Meets National Electric Code

● SEPARATE CONTROLLER AVAILABLE FOR USE WITH MPD
~ See AMOT form 1309, Model 8545B for MPD Controller.
~ Complete Metal Particle Detector system available from AMOT.

Applications

AMOT¹s MPD Switch can detect and alert equipment operators of the presence of metal particles in non-conductive fluid lubrication systems (lube oil, trans-mission fluid, etc.). The MPD can be used with AMOT¹s MPD Controller or an alternate, approved controller. Common MPD applications would include the following:

● RECIPROCATING EQUIPMENT
~ Gas Engines
~ Diesel Engines
~ Compressors

● ROTATING EQUIPMENT
~ Gas Turbines
~ Steam Turbines
~ Transmissions and Gear Boxes
~ Pumps
~ Compressors

Operation

AMOT's MPD detects metal particles in lubrication fluids.

The MPD Must be used with an intrinsically safe control system in hazardous areas.

Operation of AMOT¹s Metal Particle Detector switch (MPD) is simple and straight forward. Process Fluid, such as lube oil or transmission fluid, enters at the top of the MPD¹s body. Fluid then travels through a perforated board containing a plated electrical grid on the board¹s top and bottom sides. Fluid exits through the bottom of the MPD body. (Refer to Figure 1.)

Activation of the MPD switch occurs when metal particles bridge the gaps on the MPD¹s electrical grid and complete a normally open (N.O.) electrical circuit to drive an alarm or shutdown relay. (Refer to Figure 2.)
