Working Principle:
The SR5300A receives process signals from up to 32 field sensors. Each signal is conditioned by dedicated input circuitry and converted by a high-precision A/D converter. The processed value drives a corresponding heated stylus pen, which burns a continuous line onto the moving 100 mm chart paper. The paper advances at the selected speed (6.25–100 mm/h). Alarm events cause the pen to mark a distinct annotation on the chart. The GPIB interface allows a connected computer to read chart data digitally for archival.

Advantages & Highlights:

• 32 channels on a single recorder — eliminates the need for multiple units
• Permanent paper record — provides legally defensible documentation for regulatory audits
• Heated-stylus recording produces high-contrast, smudge-proof charts
• GPIB interface enables digital backup of paper records
• A version offers enhanced accuracy and additional features over the standard SR5300

Applicable Industries:

• Pharmaceutical Manufacturing (FDA 21 CFR Part 11 compliance)
• Chemical Processing
• Power Plants (boiler and turbine monitoring)
• Oil and Gas Refining
• Environmental Monitoring Stations
• Food and Beverage (HACCP documentation)
• Research and Development Laboratories

Installation Requirements:

• Place on a stable, level benchtop or mount in a 19-inch rack (with adapter)
• Provide 100–240 V AC power with ≤ 5% voltage fluctuation
• Connect field signals using shielded cables; ground shields at the recorder end
• Load chart paper from the front before powering on
• Ensure ambient temperature is between 0 °C and +50 °C
• Provide minimum 100 mm clearance in front for paper access

Usage Precautions:

• Use only Yokogawa-specified 100 mm chart paper (B9565AW or equivalent)
• Replace pen tips when recording quality degrades (visual inspection every 3 months)
• Do not touch the heated stylus pens during operation — risk of burn injury
• Back up critical chart data via GPIB before the paper roll is exhausted
• Clean the pen assembly and paper path with a soft brush monthly
• Calibrate annually using Yokogawa-certified calibration equipment
