Honeywell DR4500 Circular Chart Recorder

Honeywell DR4500 Circular Chart Recorder — Paper-Based Process Recording for Saudi Arabian Industrial Applications

The Honeywell DR4500 is a circular chart recorder providing permanent paper-based process recording for Saudi Arabia's industrial facilities. Despite the digital age, paper chart recorders remain the regulatory standard for many Saudi Aramco and SEC applications where permanent, auditable process records are required by the Saudi Food and Drug Authority, environmental agencies, and plant operating permits.

The DR4500's simplicity is its strength in Saudi Arabia's harsh industrial environment: no network configuration, no firmware updates, no touchscreen calibration — just a chart and a pen. For plant operators in remote Aramco field stations (Hawiyah, Shaybah, Khurais), the DR4500 delivers reliable recording without IT infrastructure.

Key Features

Up to 12 Channels: 1, 2, 4, 6, or 12 input channels — from single-point temperature monitoring to comprehensive process recording across entire plant units.

Multiple Input Types: Thermocouple, RTD, mV, 4–20 mA, and voltage inputs — handles all standard process measurement signals without signal converters.

12-Hour or 24-Hour Chart: Configurable chart speed for continuous recording — 24-hour charts are standard for most Saudi process applications.

Intrinsically Safe Option: Intrinsically safe version available for Zone 0 classified areas — direct installation in hazardous zones without barriers.

Applications in Saudi Arabia

SEC Power Plants: Boiler steam temperature and pressure recording on 24-hour circular charts — regulatory requirement for SEEC's environmental monitoring compliance.

Aramco Wellhead Separators: Oil, water, and gas flow rate recording on circular charts — permanent record for production allocation and custody transfer documentation.

Frequently Asked Questions

Q1: What chart paper is required for DR4500? DR4500 uses standard 250mm circular charts — Honeywell part number C317-0124 for 24-hour charts. RAZZ stocks chart paper in Jeddah for same-day dispatch. Custom chart scales are available for specific process ranges.

Q2: Can DR4500 record 4–20 mA process signals? Yes — the DR4500 accepts direct 4–20 mA input without external signal converters. For applications where the transmitter is located far from the recorder, RAZZ recommends using signal isolators to prevent ground loop issues.
