TF Non-Contact Voltage Detection and Indication System
- Advanced Non-Contact Sensing: A state-of-the-art system capable of detecting high voltage (120V to 33kV and above) from a distance—up to 15 meters—without any physical contact.
- Clear Visual Indicators: Equipped with a dual/single side LED display that clearly shows
- RED – Voltage Present
- GREEN – Voltage Absent
- YELLOW – Sensor Failure
- Wired Signal Extension: The RED, GREEN, and YELLOW indications can also be extended through wired outputs, enabling integration with external alarm, display, or automation systems.
- Adjustable Sensing range: Configurable via built-in Wi-Fi UI; users can set cutoff voltage and sensitivity (1–5) to fine-tune detection range based on operational needs.
- Robust and Reliable Design: Maintenance-free sensor with high efficiency and built to operate in extreme conditions (−30°C to +70°C, up to 5000 meters altitude).
- Versatile Deployment: Suitable for industrial, railway (OHE), and high-voltage environments. Comes with waterproof or non-waterproof enclosures, 12”x6” display (customizable), and rugged connector interfaces.
- Smart Connectivity: Built-in Wi-Fi enables real-time adjustment through an easy-to-access web interface.
- Proven Detection Range:
- 240V: Up to 2 meters
- 11kV: Up to 5 meters
- 25kV: Up to 10 meters
- 33kV: Up to 15 meters
