On June 19 and 20, Pepperl+Fuchs will be at the Valve World Americas Expo in Houston, Texas, at booth 327. We will be highlighting patented 2:1 technology for hazardous areas and the F31K2 valve position sensor.
Since the first expo in 2011, manufacturers, distributors, engineering firms, and end users in the industrial flow control industry have been coming from around the world to learn about the latest technologies in their industry. This year, more than 250 international companies will be showcasing their newest products, with North American and South American valve markets being the main focus.
Patented 2:1 technology from Pepperl+Fuchs offers a potential savings of 50% on sensor wiring needs in hazardous areas. Signals from NAMUR sensors can be transmitted in pairs to a control device via one line. Two digital sensors are wired antiparallel to one strand pair that is connected to the switch amplifier.
2:1 technology is ideal for system enhancements that require additional signals to be routed via existing and possibly at-capacity field wiring. Pepperl+Fuchs also provides this technology in sensor and valve interface modules for fieldbus applications.
Quarter turn valves often use two independent sensors to provide valve position feedback. Pepperl+Fuchs’ dual sensor, the F31K2, combines two inductive sensors in one modular package that also includes a high visibility beacon for local on/off position indication. This approach reduces installation and maintenance costs. Durable, noncontact, and wear-free detection makes it ideal for harsh conditions. Mounted directly on a valve actuator, the sensors transmit the valve position to a control system, ensuring absolutely reliable processes.
F31K2 dual sensors are designed for outdoor use with no compromises. The open solution allows status monitoring from a distance with its highly visible integrated valve position indicator and translucent housing. The modular housing design enables easy operation, installation, and diagnostics. The sensor’s unique dual housing provides double the mechanical protection and a high IP rating. The housing materials ensure high resistance to UV, temperature, and corrosion. NAMUR Ex i (Zone 0/20) and Ex nA (Zone 2/22) versions are available.
