The Topworx TXP-M20GNPM is a rugged, high-precision valve position sensor designed for industrial automation systems operating in extreme and hazardous environments. Built with a corrosion-resistant 316L stainless steel housing (IP68/IP69K-rated), this sensor delivers reliable performance under harsh conditions, including exposure to high-pressure washdowns, abrasive chemicals, and temperatures ranging from -40°C to +120°C.
Utilizing advanced Hall Effect sensing technology, it detects valve positions (open/closed or intermediate states) without mechanical contact, ensuring zero wear, long-term accuracy, and maintenance-free operation. Compatible with ball, butterfly, and gate valves, the TXP-M20GNPM is ideal for oil and gas, chemical processing, marine, and food-grade industries demanding robust and precise valve monitoring.
- Output Signal: Dual NPN/PNP proximity switches (sourcing, 300 mA) with short-circuit protection
- Supply Voltage: 10-30V DC (universal input with reverse polarity protection)
- Enclosure Rating: IP68/IP69K, NEMA 6P
- Housing Material: 316L stainless steel with PEEK sensing face
- Operating Temperature: -40°C to +120°C
- Connection Type: M12x1 quick-disconnect connector with PUR shielded cable
- Certifications: ATEX/IECEx (Zone 1/21), SIL 2 compliance, FDA 21 CFR 177.2600 (food-grade)
- Sensing Range: Adjustable via magnetic cam (up to 15 mm)
The TXP-M20GNPM is widely deployed in offshore oil and gas platforms to monitor subsea valve positions in explosive atmospheres, ensuring leak detection and safety compliance. In chemical plants, it provides critical feedback for valves handling corrosive fluids such as hydrochloric acid or caustic soda.
Food and beverage facilities utilize its FDA-compliant design for hygienic valve control in CIP (Clean-in-Place) systems, while marine environments rely on its saltwater-resistant construction for ballast valve monitoring. Its IP68/IP69K rating also makes it suitable for wastewater treatment plants, pharmaceutical cleanrooms, and high-pressure washdown applications requiring submersion resistance.
