- Model: TZIDC V18345
- Order Code: 1010121001
- Communication: HART Protocol
- Protection Rating: IP66 / IP67
Functional Features:
- Auto-Calibration: One-touch automatic setup and tuning for rapid commissioning.
- Advanced Diagnostics: Monitors valve friction, air consumption, and travel deviation.
- Fail-Safe Action: Configurable fail-open, fail-close, or fail-in-place modes.
Application Scenarios:
Critical control valves in power plants, refineries, and marine applications.
Performance Parameters:
- Accuracy: ±0.5% or better.
- Air Consumption: Ultra-low standby consumption for energy efficiency.
Material Composition:
Die-cast aluminum or stainless steel housing with epoxy coating for harsh environments.
Structural Features:
Dual-chamber design separating electronics from pneumatic components. Local LCD display and buttons.
Working Principle:
Uses a non-contact position sensor to track valve travel. The microprocessor adjusts the pneumatic relay to maintain the exact position commanded by the 4-20 mA signal.
Installation Requirements:
Mount according to IEC 60534 standards. Ensure adequate clearance for the display and pneumatic tubing.
Usage Precautions:
Use clean, dry instrument air. Protect the positioner from excessive mechanical vibration.
