In industrial scenarios requiring paper-based data archiving (such as chemical batch recording and pharmaceutical compliance traceability), paper recorders—with their dual data management capabilities of “electronic storage + paper printing”—are the preferred choice for meeting compliance and traceability needs. The GT68PR Paper Recorder is a 6-channel integrated device that combines a 4-inch color screen display, dot-matrix printing, and electronic storage functions. It supports multi-signal input and dual data backup, adapting to small-scale industrial monitoring scenarios that require paper-based data archiving.
1. Product Positioning and Core Scenarios
The GT68PR is a 6-channel paper recorder. Its core function is to enable real-time paper-based printing (including curves and numerical values) via a dedicated connection between the integrated dot-matrix printer and the recorder, while simultaneously storing data electronically in the internal memory. It supports input of signals such as current and voltage, making it suitable for scenarios that require paper-based data archiving—such as batch production records in the chemical industry, compliance traceability in the pharmaceutical industry, and paper-based archiving of process parameters for small equipment.
2. Basic Structure and Hardware Configuration
- Appearance and Dimensions: Features a 160160mm panel size, integrating a display screen and printer module. It fits a 152157mm mounting hole, complying with standardized installation for industrial instruments;
- Display and Printing: Equipped with a 4-inch high-definition color LCD screen, supporting multi-format display (numerical values, bar graphs, curves, etc.). It is paired with a dot-matrix ribbon printer, compatible with 57mm roll paper (30mm outer diameter) with an effective printing width of 48mm, meeting the clarity requirements for paper-based records;
- Power Supply and Environment: Supports dual power supply (AC220V±10%/50Hz, DC24V±10%), operates in temperatures of 0~50℃ and humidity of 10~85%, with a preheating time of 30 minutes, adapting to conventional indoor industrial environments.
3. Core Product Features
The GT68PR’s functional design focuses on “6-channel monitoring + dual data management”, with core advantages including:
- Integrated Printing and Display: The printer connects to the recorder via a dedicated line, supporting manual/automatic printing of data curves. Printing styles (with/without channel numbers) can be freely configured, balancing paper-based archiving and visualization needs;
- High-Precision Multi-Signal Collection: Full-range 0.2% high-precision collection, with 6 universal signal inputs compatible with multiple signal types (current, voltage, etc.). No module replacement is required to adapt to different sensors;
- Dual Data Storage and Backup: 16MB memory can store 900,000 electronic records. It also supports data backup via USB interface and data retrieval via RS485 communication, achieving “electronic + paper” dual backup in combination with paper printing;
- Usability and Expandability: Supports Chinese-English interface switching, and is equipped with 2 channels of 24V power distribution and 2 channels of current transmission output, meeting sensor power supply and signal transmission needs.
