1. Product Overview: Topworx TXP-M2CGNMM Non-Contact Valve Position Sensor
The Topworx TXP-M2CGNMM is a heavy-duty, non-contact valve position sensor engineered for industrial automation systems operating in extreme and hazardous environments. Featuring a corrosion-resistant 316L stainless steel housing with an IP68/IP69K-rated enclosure, this sensor withstands harsh conditions, including high-pressure washdowns, abrasive chemicals, and temperatures 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-M2CGNMM is ideal for oil and gas, chemical processing, marine, and food-grade industries requiring robust performance in corrosive or explosive atmospheres.
2. Key Technical Specifications
3. Industrial Applications and Use Cases
The TXP-M2CGNMM is critical for monitoring valve positions in offshore oil rigs and refineries, ensuring leak detection and safety compliance in Zone 1/21 explosive atmospheres. In chemical processing plants, it provides precise feedback for valves handling aggressive acids, alkalis, or high-purity gases. Food and beverage facilities leverage its FDA-compliant, crevice-free design for hygienic valve control in CIP (Clean-in-Place) systems, while marine applications rely on its saltwater-resistant construction for ballast valve monitoring. Its IP68/IP69K rating also makes it suitable for submerged environments like wastewater treatment plants and high-pressure washdowns in pharmaceutical manufacturing.
4. Competitive Advantages and Unique Features
5. Functional Capabilities and Operational Benefits
The TXP-M2CGNMM delivers real-time valve position feedback to control systems, triggering automated shutdowns or alarms during operational deviations. Its dual outputs support redundant safety loops, critical for blowout preventers (BOPs) in oil drilling and emergency isolation valves in chemical plants. The IP68/IP69K rating ensures reliability in submerged or high-pressure washdown scenarios, minimizing maintenance interruptions. With optional IO-Link compatibility, it enables predictive maintenance by transmitting diagnostic data such as signal integrity and environmental conditions. The shielded PUR cable reduces EMI interference, while the ceramic-coated face enhances durability in abrasive media. These features make the TXP-M2CGNMM a future-proof solution for Industry 4.0-driven automation and smart facility management.
