Pro Meter S PLC

The Nordson Pro-Meter S PLC raises the bar in the high-speed application of sealants and adhesives in automotive assembly processes, with innovative features that deliver invaluable time savings and the highest quality output and exacting precision.

Overview


Pro-Meter® S PLC is supplied with positive material pressure by an Electric or Pneumatic Rhino Unloader and is integral to Nordson's complete dispensing system for automotive assembly applications
 
 

Features and Benefits


Unmatched Versatility: Positive rod technology is ideal for dispensing all types of materials, in all types of applications, such as swirl, patch, dot, daub and bead - extrude or bead - stream.
 
Unsurpassed Precision: Positive rod displacement delivers meticulous accuracy in volumetric dispensing, regardless of material type, material temperature, or material viscosity.
 
Industry-Leading Simplicity: Design eliminates typical wear items that run the length of the cylinder, and offers visual indication of eventual packing or seal failure to minimize unforeseen problems.
 
Cost-Saving Durability: Nordson’s exclusive ScoreGuard® surface finishing treatment resists scratching and pitting on the plunger rod, prolonging seal packing life, and reduces frequency of service and maintenance costs.
 
Assured Material Quality: First-in, first-out design of fluid paths prevents material from being stuck in the meter for longer than its desired shelf life, which can allow expired material to be dispensed without the user’s knowledge.
 
Technology unlocks new possibilities in performance: A servo actuator on every Pro-Meter S PLC can change speed mid-stroke, to adjust to bead width or robot speed changes. Alternatively the system can start and stop on the fly, to provide accurate dots and daubs, producing multiple precise shots in succession before the need to reload, resulting in lower cycle time and increased productivity. 
 
Industry’s simplest installation and maintenance: With a streamlined dress-out and simplified installation, quick change packings and an innovative split coupler to support in situ maintenance, the system improves safety and reduces complex maintenance routines.

Positive Rod Displacement Technology - Exact Ratios Every Time

No matter the material, positive rod displacement metering proportions materials to the exact volumetric ratio every time; even with notoriously difficult materials like abrasives that can cause machine wear.


Principle


As the metering rod moves through the cylinder, material is directed by inlet and outlet valves to ensure the displaced material is directed downstream. The shot size of the dispense is determined by the distance the metering rod travels whereas the flow rate is determined by the speed of such travel.

Advantages


  • High shot adjustability
  • Minimal wear components
  • Ability to handle abrasive materials
  • Air can be purged from the top of the cylinder without turnover
  • Easy to access and complete repairs 
  • If a new ratio is required, only the rod would need to be changed as opposed to the entire cylinder
  • Provides longer seal life than rotation-based metering principals
