Overview
The Trimos HS Series Multi-Function Length Measuring Machine is a high-precision, benchtop metrology system engineered for traceable dimensional calibration and verification of mechanical length standards and industrial gauges in production, quality control, and calibration laboratory environments. Unlike comparative or incremental measuring systems, the HS series employs a long-range, high-stability linear encoder—based on absolute-positioning optical grating technology—to deliver true absolute length measurement across its full 3050 mm travel range. This architecture eliminates cumulative error, warm-up drift, and homodyne/heterodyne interference artifacts commonly associated with traditional laser interferometers operating in non-vacuum or temperature-fluctuating conditions. Designed and manufactured in Switzerland, the HS platform conforms to the foundational metrological principles defined in ISO/IEC 17025, ISO 10360 (CMM acceptance testing), and VDI/VDE 2617 Part 1, ensuring compatibility with accredited calibration workflows and GLP-compliant documentation requirements.
Key Features
- True absolute measurement over 0–3050 mm using a thermally stable, vacuum-sealed long-range optical grating scale with integrated reference marks;
- Sub-micron resolution of 0.1 µm and certified accuracy of ±0.1 µm (at 20 °C ± 0.5 °C, humidity 40–60 % RH, no air turbulence);
- Modular mechanical architecture featuring granite base, precision-ground dovetail ways, and low-hysteresis kinematic carriage system for minimal Abbe error and thermal expansion compensation;
- Integrated digital probe interface supporting analog LVDT, capacitive, and strain-gauge-based contact sensors (e.g., Trimos TESA-style probes) with real-time 24-bit A/D conversion;
- Passive environmental stabilization: no active air conditioning or vibration isolation table required under standard metrology lab conditions;
- Compliance-ready design with hardware-level encoder zero-reset capability, audit trail logging, and firmware-signed calibration certificates.
Sample Compatibility & Compliance
The HS series is optimized for the calibration of line standards, end standards, gauge blocks (Grade K, 0, 1 per ISO 3650), plug and ring gauges (ISO 1938), bore gauges, micrometers (ISO 3611), vernier calipers (ISO 13281), dial indicators (ISO 10791-6), and cylinder bore gauges. All measurement protocols align with ISO 5725 (accuracy and precision), ISO 14253-1 (GPS — Geometrical Product Specifications), and ASTM E1142 (Standard Practice for Calibration of Length Standards). The system supports traceability to national metrology institutes (e.g., METAS, PTB, NIST) via documented uncertainty budgets compliant with GUM (JCGM 100:2008). Full compliance with ISO/IEC 17025 clause 6.4.10 (measurement equipment verification) and FDA 21 CFR Part 11 (electronic records/signatures) is achievable when paired with Trimos-certified software and audit-logged operation.
Software & Data Management
The HS series operates with Trimos Metrology Suite (TMS) v5.x — a Windows-based, 64-bit metrology application validated for ISO 17025 laboratories. TMS provides automated calibration routines per ISO 3650 Annex B (gauge block calibration), customizable report templates (PDF, XML, CSV), multi-language UI support (EN/DE/FR/ES), and built-in uncertainty calculation engine per GUM Supplement 1. All measurement data are stored with timestamped metadata, operator ID, environmental sensor logs (temperature, humidity), and digital signature authentication. Software configuration is locked via hardware dongle and supports role-based access control (RBAC) for QA/QC supervisors, technicians, and auditors. Exported reports include full traceability chains, certificate numbers, and revision-controlled calibration history — essential for internal audits and external accreditation assessments.
Applications
- On-site calibration of workshop-grade length standards without requiring a Class 1 metrology lab;
- Verification of gage repeatability and reproducibility (GR&R) in automotive Tier-1 supplier PPAP submissions;
- Periodic verification of coordinate measuring machine (CMM) ball bars and step gauges;
- Calibration of master gauges used in aerospace manufacturing (AS9100 Rev D Clause 7.1.5.2);
- Uncertainty analysis for ISO/IEC 17025 scope expansion in dimensional metrology labs;
- Support for ISO 9001:2015 Clause 7.1.5 (monitoring and measuring resources) compliance evidence generation.
FAQ
What environmental conditions are mandatory for achieving ±0.1 µm accuracy?
The specified accuracy requires stable ambient temperature at 20 °C ± 0.5 °C, relative humidity between 40–60 % RH, and absence of air drafts or floor vibrations exceeding 2.5 µm/s RMS (per ISO 25378). No active climate control is needed if the facility meets ISO 554 standard conditioning.
Can the HS system be used for calibration of gauge blocks longer than 100 mm?
Yes — the 3050 mm travel enables direct calibration of Grade K and Grade 0 gauge blocks up to 1000 mm in length using the “step-and-repeat” method per ISO 3650 Annex C, with full uncertainty propagation.
Is firmware and software validation documentation available for FDA-regulated environments?
Trimos provides IQ/OQ documentation packages, software validation protocols (SVP), and 21 CFR Part 11 compliance statements upon request — all aligned with ASTM E2500 and ICH Q9 guidelines.
Does the system support automated reporting to LIMS or ERP platforms?
Yes — TMS includes OPC UA and RESTful API interfaces for bidirectional data exchange with LabWare LIMS, SAP QM, and Oracle Manufacturing Cloud.
