“The sensor has a number of advantages which impressed us immediately,” says Jos De Jong from Bray Controls, a valve company that enjoys a long-standing working relationship with both Pepperl+Fuchs and Frisia Zout. “This sensor is compact and the beacon in a weatherproof housing gives a very clear indication of the valve’s position. With the inductive sensors, there is no need for mechanical contacts – what is not there cannot corrode! The fully encapsulated housing design of the F31K2 guarantees additional protection and high impermeability. At a very reasonable price, the sensor looked like the perfect solution to me”, says De Jong.
Optimized for outdoor use, the F31K2’s housing materials provide high UV protection and are resistant to extreme temperatures, salt water, and corrosion. The beacon is visible from long distances and gives on-site operators reliable valve position information at a glance. The modular housing is made of a ruggedized, translucent plastic and LEDs that indicate the power supply, sensor, and valve conditions are integrated into the encapsulated sensor module. Thanks to the large terminal compartment and pluggable terminal block, cables that are rigid or have large diameters do not pose problems in environments where mounting work could prove difficult.
“The sensors have worked perfectly. The on-site operators are extremely satisfied, not least because of the high visibility of the signals given off by the beacon. I am certain that, over time, we shall replace all of our switch boxes with F31K2 sensors,” concludes Rudolf Bergsma.
