The Yokogawa MV1012 is a 12-channel portable paperless recorder designed for multi-parameter data acquisition in laboratory, field, and industrial environments. It captures temperature, voltage, and contact signals with selectable sampling rates—1 second per channel in normal mode or 125 ms per channel in fast sampling mode—and stores data to internal Flash memory or external Compact Flash and USB media.
Technical Specifications
• Channels: 12 input channels
• Sampling Rate: 1 second per channel (normal mode); 125 ms per channel (fast sampling mode)
• Internal Memory: 80 MB, 200 MB, or 400 MB Flash memory options
• Storage Duration: Approximately 75 days (200 MB) or 148 days (400 MB) continuous recording at 12 channels, 1-second intervals
• External Storage: Compact Flash (up to 1 GB) and USB memory support
• Display: 5.5-inch TFT color LCD, 320 × 240 dots
• Input Types: Thermocouples (R, S, B, K, E, J, T, N, W, L, U); RTD (Pt100, JPt100, Pt50, Cu10, Cu25); DC voltage (±50 V); contact input (TTL level, >2.4 V ON, <2.4 V OFF)
• Measurement Accuracy: Type K thermocouple example: ±(0.2% of reading + 4°C) or ±10°C at 0 to 100°C
• A/D Integration Time: 16.7 ms or 1.67 ms depending on mode
• Alarms: Up to 4 per channel; high/low limit, difference high/low, rate-of-change high/low
• Event Actions: Up to 40 configurable actions
• Power Supply: 90–132 VAC or 180–264 VAC (AC adapter); 12 VDC or 24 VDC (DC supply)
– Key Features
• Dual-mode sampling accommodates both standard monitoring and high-speed transient capture
• Multiple data-saving modes: Free (continuous), Trigger (with pre-trigger), Manual, Auto-save, and Snapshot
• Binary or text format export to external media; internal storage uses binary format
• Comprehensive alarm and event-action engine for condition monitoring and automated response
– Typical Applications
Temperature profiling, process validation, equipment diagnostics, thermal transient analysis, multi-point data logging across manufacturing and test environments.
– Compatibility & Integration
Accepts industry-standard thermocouple and RTD sensors. Exports via Compact Flash card or USB memory for post-acquisition analysis.
