GT71R Paperless Recorder: An Intelligent Integrated Terminal for Industrial Multi-Parameter Monitoring

In scenarios such as quantitative packaging, batching, and filling in industries like petroleum, chemical engineering, and pharmaceutical food, precise fluid quantitative control is key to ensuring production efficiency and product consistency. The GT-DL3100D Quantitative Control Box, with an ARM microprocessor as its core, is paired with flow transmitters, sensors, solenoid valves, and other components to realize quantitative calculation, control, and management of fluid media. It also integrates functions such as data display, communication, and protection, serving as an integrated solution for industrial fluid quantitative scenarios.

1. Product Positioning and Application Scenarios

The GT-DL3100D is an ARM processor-based quantitative control system. Its core function is to collect fluid signals through supporting flow transmitters and sensors (e.g., vortex street, turbine, electromagnetic flowmeters), complete flow metering via the ARM’s computing capability, and link with solenoid valves to achieve quantitative start-stop control.
 
It is suitable for quantitative operation needs in industries like petroleum, chemical engineering, and pharmaceutical food, including processes such as quantitative feeding, loading, batching, discharging, splitting, and gas filling. It can be used for independent control of a single workstation or connected to production line systems for batch management.

2. Product Structure and Basic Configuration

The control box offers two structural forms to adapt to different scenario requirements:
 
  • Large control box: Integrates the control box and valve, supporting more complex linkage control;
  • Small control box: Only includes a separate control module, suitable for lightweight installation scenarios;
 
Core hardware parameters include:
 
  • Display and processor: Equipped with a 128*64 dot-matrix gray-white LCD display with a display accuracy of ±0.2% F.S.; adopts an ARM Cortex-M3 32-bit RISC core to ensure efficient execution of data operations and control commands;
  • Installation and dimensions: The large control box measures 300400200mm, and the small one 200300150mm, conforming to standardized installation in industrial sites;
  • Power supply and environment: Supports 220VAC, 24VDC, and 12VDC power supplies; operates in temperatures of 0~50℃, humidity of 0~85% RH, and altitude ≤2000 meters; the instrument’s net weight is ≤1.0Kg, adapting to most industrial working conditions.

3. Core Functional Features: Full-Process Quantitative Management Capability

The functional design of the GT-DL3100D focuses on “precise quantification + convenient operation + data management”, with core features including:
 
  • Basic control functions: Supports display, alarm, and control of fluid flow, and is compatible with signal types from various flow sensors (e.g., vortex street, turbine, electromagnetic);
  • Metering and conversion: Automatically converts flow units; the flow coefficient of differential pressure flowmeters can be calculated automatically, adapting to metering needs of different media;
  • Data management: Features audit records (power outage and quantitative records) and query functions for cumulative reports (daily, monthly, annual), providing data support for production traceability and management;
  • Communication and expansion: Supports the Modbus RTU protocol and RS485/RS232C communication interfaces, enabling connection to upper computer systems; also supports standard current transmission output with flexible signal source selection;
  • Power supply and protection: Provides multi-specification feed output (for sensor power supply), and built-in mechanisms such as data protection (permanent storage during power outage), hardware clock (precise operation after power recovery), and flow input channel protection (against signal damage) to ensure system stability;
  • Adaptability and convenience: Supports temperature input channels, multi-power supply (reducing system costs), and features density compensation (compensation calculation for high/low temperature signals), flow retransmission (meeting automatic control needs), clock/printing functions, balancing scenario adaptability and operational efficiency.

4. Technical Parameters and Performance Guarantee

  • Input functions: Covers flow (4-20mA, 0-10mA analog/0-5000Hz frequency), temperature (0-10mA, 4-20mA/Pt100), and pressure (0-10mA, 4-20mA) channels, compatible with multiple sensor types;
  • Output functions: Includes power distribution output (12VDC+24VDC, max 30mA per channel), transmission output (4-20mA, 500Ω load), and 3 relay outputs (contact capacity 250VAC/3A), meeting control and linkage requirements;
  • Reliability design: Excellent anti-interference performance and high stability; equipped with a human-machine interface and insulation protection, it is easy to operate and highly safe, adapting to long-term continuous operation in industrial scenarios.

5. Product Value Summary

The core advantages of the GT-DL3100D Quantitative Control Box lie in “integration + precision + adaptability”: With the ARM processor as the core, it integrates full-process functions such as flow metering, valve control, data management, and communication, avoiding the complexity of multi-device assembly; ensures quantitative precision through automatic conversion and density compensation; and covers the needs of different industrial scenarios with multi-sensor compatibility, multi-power supply modes, and multi-protection mechanisms.
 
For industries like petroleum and chemical engineering that require quantitative operations, this device not only improves the automation and precision of the quantitative process but also enables traceability and centralized management of production data through data reports and communication interfaces. It is an industrial fluid quantitative management solution that balances efficiency, precision, and reliability.
