PM-1 Particle Monitor

The Proactive Monitor Contamination unit from Hy-Pro Filtration (type PM-I) allows you to recognise the contamination level changes in hydraulic and lube oil systems. On-line monitoring provides quick results and eliminates delay, error or potential doubt associated with bottle samples and oil analysis lab results.

Increasing ISO codes can indicate accelerated component or bearing wear, or symptomatic of some other issue such as insufficient filtration or breathers & worn seals.

Communication & Data Acquisition:

PM-I exports data to serial interface or optionally to a CAN-Bus (CANopen). In parallel, the configurable 4-20 mA interface can be connected. PM-I operation based on time interval or start/stop with manual or digital input. PM-i also has integrated data memory.

PM-I Principle of Operation:

PM-i uses a laser to measure particle sizes and quantity by light extinction. A measuring cell is used to calculate corresponding voltage drop from the particles passing through the PM-i.

Pressure Range:

PM-I is designed for operating pressure up to 6,090 PSI / 420 BAR. For lower pressure lube oil systems alternative inlet & outlet fittings are available if the Minimess® standard connections are too restrictive.
