Product Description
ConST326 Series Intelligent Process Calibrator: Comprehensive Product Introduction
1. Overview
The ConST326 Series Intelligent Process Calibrator, developed by Const Group (a leading Chinese calibration technology provider listed on Shenzhen Stock Exchange, 300445), is a cutting-edge field communicator designed for industrial calibration, troubleshooting, and maintenance. Tailored for harsh environments like oil refineries, chemical plants, and power stations, this device integrates HART communication, precision measurement, signal simulation, data logging, and safety compliance into a single handheld unit. Its modular design and robust functionality make it indispensable for engineers working in explosive atmospheres (Zone 0) or demanding field conditions
2. Key Features & Selling Points
2.1 Multifunctional Integration
The ConST326 eliminates the need for multiple tools by combining:
HART Communicator: Supports point-to-point, multipoint, and burst modes for seamless interaction with HART-enabled devices (e.g., pressure transmitters, temperature sensors). It executes universal, common, and device-specific commands, including sensor trimming (e.g., Honeywell ST3000, Rosemount 3051)
Signal Generator/Simulator: Simulates RTD, thermocouple (15 types), mA, mV, V, and frequency signals. Pulse excitation stabilizes in 1ms, ideal for high-speed PLCs
Measurement Tools: Acts as a True RMS multimeter (up to 30V), loop power supply (24V), and pressure indicator (with external CDP-Ex modules).
Data Logger: Records pressure, temperature, and electrical signals with 500 snapshot slots and 10,000 task files
Thermal Calculator & Unit Converter: Simplifies on-site calculations for engineers
2.2 Explosion-Proof Certification (Zone 0)
The ConST326Ex model holds ATEX/IECEx/CSA/UKCA certifications (Ex ia IIC T4 Ga), making it safe for use in explosive gas environments. Its IP54-rated casing and intrinsically safe battery ensure reliability in oil rigs, pharmaceutical plants, and chemical facilities
2.3 Advanced HART Communication
Dual Modes: Autocal Mode offers a simplified Chinese UI for routine tasks; Handheld Mode (using SDC625 resolver) accesses device-specific commands
Compatibility: Supports >50 HART device families, including Emerson, Endress+Hauser, and Rosemount. Regular firmware updates keep it aligned with new devices
Loop Calibration: Built-in 250Ω resistor and 24V power enable offline/online calibration without additional tools
2.4 Paperless Calibration
Documentation Suite: Preloaded tasks for temperature, pressure, flow, and loop equipment (e.g., vortex flowmeters, limit switches). Automates error judgment and generates compliance-ready reports
ACal Software Integration: Optional PC software automates data collection, analysis, and certificate generation when paired with temperature/pressure sources
2.5 Precision & Stability
Accuracy: Up to 0.005% RD + 0.005% FS (ConST326 base model), outperforming competitors like Emerson 475
Thermocouple Compensation: Patented mini-TC interface stabilizes cold junctions in 10 seconds (vs. industry-standard minutes) using ZL201820031598.4 technology
Humidity Resistance: Maintains accuracy at 95% RH, critical for tropical or high-moisture environments
2.6 User-Centric Design
5-inch HD Touchscreen: Semi-transflective display ensures visibility under direct sunlight
Ergonomic Hardware: Weighs 1.33kg, with a glove-friendly interface and one-handed operation
Smart Battery: Removable 8-hour Li-ion pack supports hot-swapping for uninterrupted fieldwork .
