Description
YOKOGAWA SR1008B62 Single-Channel Strip Chart Recorder
1. Product Description
The YOKOGAWA SR1008B62 is a compact single-channel strip chart recorder designed for industrial data logging and process monitoring. Part of Yokogawa’s SR series, the SR1008B62 records analog signals (voltage, current, temperature) on a 20-meter paper chart, providing real-time visualization of critical parameters. With support for thermocouples (J/K/T), RTDs (Pt100), and DC voltage inputs, it is ideal for applications requiring continuous monitoring in manufacturing, energy, and research. The recorder features adjustable chart speeds (10–600 mm/min), alarm functions for threshold deviations, and a durable design (144 mm × 144 mm × 280 mm) for panel mounting. While now a legacy model, it offers reliable analog recording for systems requiring retrofittable or cost-effective data logging.

3. Advantages and Features
- Single-Channel Simplicity: Focused recording for applications with one critical parameter (e.g., temperature, pressure).
- Wide Input Compatibility: Supports thermocouples, RTDs, and voltage inputs for versatile sensor integration.
- User-Centric Design: Easy-to-read 100 mm chart, quick paper replacement, and front-panel calibration controls.
- Reliable Alarm System: Instant alerts for out-of-range values, reducing downtime in industrial processes.
- Legacy System Compatibility: Direct replacement for older Yokogawa recorders (e.g., LR series) with identical mounting dimensions.
4. Application Areas and Case Studies
- Manufacturing: Monitoring oven temperature in plastics production.
- Energy: Tracking boiler pressure in power generation.
- Food & Beverage: Logging pasteurization temperatures in dairy processing.
Case Study: A pharmaceutical manufacturer used the SR1008B62 to monitor freeze-dryer temperature during drug production. Its single-channel precision ensured compliance with FDA regulations, while the alarm function triggered immediate shutdowns during temperature excursions. The analog format simplified integration with existing batch control systems, avoiding costly digital upgrades.
5. Competitive Comparison
Compared to legacy single-channel recorders:
- Input Flexibility: Supports RTD/thermocouple/voltage (vs. many single-technology models).
- Compact Footprint: 144 mm × 144 mm panel size (vs. bulkier 190 mm alternatives).
- Power Options: Dual AC/DC power (24V DC optional) for hybrid industrial setups.
- Cost-Effective Maintenance: Lower replacement costs than multi-channel digital recorders for single-parameter needs.

6. Selection Recommendations
- Single-Parameter Systems: Ideal for applications requiring one-channel monitoring (e.g., standalone machines).
- Legacy Upgrades: Replace older Yokogawa SR/LR models with identical mounting and wiring.
- Input Requirements: Confirm sensor type (e.g., K-type thermocouple, Pt100 RTD) matches recorder inputs.
- Power Needs: Choose AC (standard) or DC (24V) variant based on panel power availability.
7. Installation and Usage Notes
-
Wiring: Use twisted-pair cables for thermocouple/RTD inputs to minimize noise.
-
Paper Handling: Replace rolls every ~200 hours (at 600 mm/min); store paper in humidity-controlled environments.
-
Calibration: Annual verification recommended using Yokogawa’s calibration tools (e.g., Model 370013).
-
Discontinuation Plan: Transition to Yokogawa’s digital recorders (e.g., MW100) for long-term support and data integration.
