ZXTX : Precision Calibration for Power and Industrial Applications
In the power and industrial sectors, accurate and reliable calibration of process signals is critical to ensuring operational safety, efficiency, and compliance. The ZXTX Series Multifunction Process Calibrator addresses this need as a high-precision, handheld instrument designed to streamline signal measurement, output, and calibration workflows for both field and laboratory applications.
1. Overview & Core Capabilities
Developed for versatile industrial signal calibration, the ZXTX Series integrates multiple functions into a single compact device. It simultaneously measures and outputs key process signals—including voltage, current, resistance, frequency, thermocouple (TC), and resistance temperature detector (RTD) signals. When paired with external high-precision intelligent pressure modules, it can also calibrate pressure transducers, eliminating the need for multiple dedicated instruments such as signal sources, resistance boxes, electronic potentiometers, and frequency meters.
This versatility makes the calibrator suitable for a wide range of use cases: on-site process calibration, equipment fault diagnosis, laboratory performance testing, and specialized applications in chemical, military, and research environments.
2. Key Technical Features
The ZXTX Series is engineered with robust features tailored to the demanding requirements of power and industrial settings:
Enhanced Environmental & Electrical Protection: With an IP67 waterproof rating and automatic protection against accidental 220V misconnection, the calibrator withstands harsh field conditions and user errors, ensuring reliability in challenging environments.
Comprehensive Signal Flexibility: It measures and outputs voltage, current (supporting both active and passive modes), resistance, and frequency. Temperature signals from thermocouples and RTDs are simulated in direct temperature units, simplifying thermal calibration workflows.
Advanced Calibration Capabilities: The device simulates two-wire transmitters, supports automatic identification of three-wire/four-wire RTD connection modes, and provides both automatic and manual cold junction compensation for thermocouple measurements and outputs. Custom TC/RTD types can also be added to meet specific user requirements.
High Accuracy & Synchronization: Available in two variants—ZXTX-2025 (0.02% accuracy) and ZXTX-1825 (0.05% accuracy)—the calibrator features two isolated channels for synchronous measurement and output, ensuring precision in multi-signal tests.
Operational Efficiency: It offers manual step, automatic step, 0–100% step, and slope output functions, along with a built-in DC24V circuit power supply for on-site debugging. A white LED backlight (with adjustable brightness) and auto-power-off function enhance usability in field environments.
3. Performance Specifications
The ZXTX Series delivers consistent precision across a wide range of signals, as detailed below:
