The Topworx TVH-E20GNPM is a high-precision, non-contact valve position sensor designed for industrial automation applications requiring reliable feedback in extreme environments. Built with a robust 316 stainless steel housing (IP66/IP67-rated), this sensor operates seamlessly in harsh conditions, including exposure to moisture, dust, vibration, and temperatures from -40°C to +85°C.
Utilizing advanced Hall Effect sensing technology, it detects valve positions (open/closed or intermediate states) without mechanical contact, ensuring long-term accuracy and minimal maintenance. Compatible with ball, butterfly, and gate valves, the TVH-E20GNPM is ideal for industries such as oil and gas, chemical processing, water treatment, and power generation.
- Output Signal: NPN/PNP proximity switch (sinking/sourcing, 100 mA)
- Supply Voltage: 10-30V DC (universal input)
- Enclosure Rating: IP66/IP67, NEMA 4X
- Housing Material: 316 stainless steel
- Operating Temperature: -40°C to +85°C
- Connection Type: M12x1 quick-disconnect connector
- Certifications: ATEX/IECEx (Zone 2/22), SIL 2 compliance
- Sensing Range: Adjustable via magnetic cam (up to 8 mm)
The TVH-E20GNPM is widely used in oil and gas pipelines to monitor valve positions in remote or explosive atmospheres, ensuring safe flow control and leak detection. In chemical plants, it provides critical feedback for valves handling corrosive or high-purity media.
Water treatment facilities deploy it to track the status of large-diameter gate valves in pumping stations, while power plants rely on it for steam valve monitoring in turbines. Its ATEX/IECEx certification makes it suitable for hazardous zones, including LNG terminals and fuel storage areas. Additionally, it supports HVAC systems and pharmaceutical manufacturing for precise valve control in sterile environments.
- Non-Contact Sensing: Hall Effect technology eliminates mechanical wear, enabling maintenance-free operation
- Corrosion Resistance: 316 stainless steel construction withstands harsh chemicals, saltwater, and high-pressure washdowns
- Flexible Integration: M12 connector and universal voltage support simplify installation with PLCs, DCS, and SCADA systems
- Safety Compliance: ATEX/IECEx and SIL 2 certifications for use in hazardous areas (Zone 2/22)
- Adjustable Sensing: Magnetic cam allows easy field calibration for diverse valve configurations
