Sartorius PMA.Power Heavy-Duty Paint Mixing Scale

Overview

The Sartorius PMA.Power is an industrial-grade heavy-duty scale engineered specifically for high-volume paint and coating formulation environments. Built on Sartorius’ legacy of precision weighing instrumentation, the PMA.Power series employs electromagnetic force compensation (EMFC) technology—ensuring long-term stability, minimal drift, and high reproducibility under variable workshop conditions. Unlike general-purpose platform scales, the PMA.Power integrates application-specific firmware optimized for multi-component batch dispensing, real-time percentage calculation, and dynamic tare management. Its mechanical architecture features a monolithic load cell design that delivers 0.1 g readability up to 35 kg capacity—enabling accurate dosing of both bulk base materials and fine-tuned colorants within a single instrument. The system is designed for seamless integration into automated paint mixing workflows, supporting direct communication with third-party tinting systems, ERP platforms, and lab information management systems (LIMS) via standardized serial protocols.

Key Features

• Monolithic high-stability load cell delivering 0.1 g resolution at full 35 kg capacity—eliminating need for secondary low-capacity scales in dual-range operations.
• 14-segment backlit LCD display with adjustable tilt angle and automatic text scrolling—optimized for legibility in low-light, dusty, or high-humidity paint shop environments.
• IP65-rated enclosure (PMA7501H variant) with corrosion-resistant housing and reinforced overload protection—designed for repeated exposure to solvents, pigments, and cleaning agents.
• Dual power configuration: AC operation with optional battery backup (PMA600H) ensures uninterrupted use during mobile or temporary setup scenarios.
• Built-in calculation functions including % deviation, factor-based scaling, and re-calculation of remaining batch quantities after partial dispensing—reducing manual transcription errors.
• Standard RS-232 interface with optional USB connectivity—enabling bidirectional data exchange with PC-based formulation software, barcode scanners, or centralized production control systems.

Sample Compatibility & Compliance

The PMA.Power accommodates standard industrial paint containers—from 5 L pails to 200 L drums—via its reinforced stainless-steel weighing platform and low-profile design. Its zero-tracking algorithm compensates for minor vibrations caused by nearby mixing equipment or foot traffic. From a regulatory standpoint, the scale supports Good Manufacturing Practice (GMP) and Good Laboratory Practice (GLP) workflows through audit-trail-enabled data logging (when paired with Sartorius LabX software). Calibration records are traceable to national metrology institutes per ISO/IEC 17025 requirements. While not certified for hazardous area use (e.g., ATEX), all models meet CE marking directives for electromagnetic compatibility (EMC) and low-voltage safety (LVD), and comply with RoHS and WEEE environmental regulations.

Software & Data Management

The PMA.Power operates independently but achieves full functionality when integrated with Sartorius LabX software. LabX provides secure user authentication, electronic signature support compliant with FDA 21 CFR Part 11, and automated report generation—including batch weight logs, deviation summaries, and calibration history. Raw weighing data can be exported in CSV or PDF format for quality audits or statistical process control (SPC) analysis. For standalone operation, the onboard memory stores up to 100 user-defined formulas with associated tolerance thresholds, enabling rapid recall without external computing infrastructure. All firmware updates are delivered via USB stick or network download—ensuring long-term maintainability across evolving IT security standards.

Applications

• Automated colorant dispensing in architectural and automotive refinish paint manufacturing.
• Batch verification and reconciliation in contract coating facilities handling OEM specifications.
• In-process quality control during solvent-borne and water-borne paint blending—where precise mass ratios directly impact viscosity, gloss, and film formation.
• Raw material receipt inspection in raw material warehouses—supporting IATF 16949-aligned documentation requirements.
• Research and development labs formulating new pigment dispersions, where repeatability across multiple 20–30 kg test batches is critical.

FAQ

What is the maximum safe overload limit for the PMA.Power series?
The scale is rated for 150% of full-scale capacity (i.e., 52.5 kg for the 35 kg model) for short-duration loading events, with automatic error notification and mechanical stop mechanisms preventing permanent sensor deformation.
Can the PMA.Power be calibrated in-house using standard weights?
Yes—internal calibration is supported using Class M2 or better reference weights; external calibration requires Sartorius-certified service technicians for traceability documentation.
Is the display unit detachable and remotely mounted?
The display module is physically separable from the load platform via a shielded 2 m cable (extendable to 5 m with optional kit), allowing wall or boom mounting in ergonomically constrained workspaces.
Does the PMA.Power support dynamic weighing during continuous pouring?
It includes a stabilized “flow mode” with configurable damping and filtering—optimized for real-time mass accumulation during gravity-fed or pump-assisted dispensing.
How often does the battery require charging on the PMA600H model?
Under typical intermittent use (10–15 weighings/hour), the rechargeable Li-ion battery provides ≥8 hours of operation; full recharge time is 4 hours via included AC adapter.
