Description
The
YOKOGAWA LR 4220E is a discontinued 2-pen strip chart recorder designed for industrial data logging applications. Part of Yokogawa’s LR series, the
LR 4220E records analog signals (voltage, current, temperature, etc.) on a 20-meter paper chart, offering real-time visualization of process data. With dual-channel recording, configurable chart speeds (10–600 mm/min), and support for DC voltage, thermocouple, and RTD inputs, it caters to diverse industries such as manufacturing, energy, and research. The recorder features alarm functions for threshold violations and a compact design (144 mm × 144 mm × 280 mm) for panel mounting. While now discontinued, it remains a reliable solution for legacy systems requiring analog data logging.

- Multi-Channel Flexibility: Simultaneous 2-channel recording for complex processes.
- Versatile Inputs: Supports thermocouples, RTDs, and DC voltage, ideal for mixed-signal environments.
- User-Friendly Operation: Adjustable chart speeds and modular design for easy paper replacement and calibration.
- Alarm System: Real-time alerts for critical parameter deviations.
- Legacy Compatibility: Suitable for retrofitting into older control systems without digital upgrades.
YOKOGAWA LR 4220E
- Manufacturing: Monitoring temperature and pressure in production lines.
- Energy: Logging data from power generators and HVAC systems.
- Research Labs: Recording experimental data in chemical or material testing.
Case Study: A water treatment plant used the LR 4220E to monitor pH and conductivity in wastewater tanks. Its dual-channel capability allowed side-by-side analysis, while alarm functions triggered immediate responses to outliers. The analog format simplified integration with legacy SCADA systems, ensuring continuous operation during a phased digital upgrade.
Against legacy chart recorders, the LR 4220E offers:
- Dual-Channel Efficiency: Simultaneous recording (vs. single-channel alternatives).
- Wide Input Range: Support for thermocouples/RTDs (vs. limited voltage-only models).
- Compact Design: Space-saving dimensions (144 mm × 144 mm) for crowded control panels.
- Cost-Effective Legacy Support: Lower maintenance costs compared to retrofitting digital systems.
- Legacy Systems: Choose the LR 4220E for analog data logging in older installations.
- Replacement Planning: Consider Yokogawa’s modern alternatives (e.g., MW100/MX100 digital recorders) for new projects.
- Input Requirements: Verify compatibility with thermocouple/RTD types (e.g., J/K/T for thermocouples).
- Space Constraints: Ensure panel space (144 mm × 144 mm) and ventilation for continuous operation.
-
Wiring: Use shielded cables for thermocouple/RTD inputs to reduce noise.
-
Paper Replacement: Replace rolls every ~200 hours (at 600 mm/min); store paper in dry environments.
-
Calibration: Perform annual checks using Yokogawa’s calibration tools (e.g., Model 370013 software).
-
Discontinuation: Plan for eventual replacement (end-of-life support may be limited).
