 August 23, 2007 - TWINSBURG, OH – Pepperl+Fuchs introduces Series F31 Valve Position Sensors. These low profile inductive proximity sensors are just 1.25 in. tall and mount directly to the top plate of any standard pneumatic actuator with just two screws for highly accurate position indication. They feature two electronic switching points integrated into one compact housing, and integral LEDs for quick visual status indication and diagnostics. Additionally, electronic switch contacts facilitate network communication and provide for direct control of a solenoid valve. “F31 valve position sensors are engineered to ensure proper, adjustment-free sensing range at all times. Because there are no adjustments to be made or mechanical components to wear, they provide highly accurate, non-contact position sensing and control of quarter turn valves in industrial, process, water, wastewater and bulk carrier applications,” says David Fink, Pepperl+Fuchs Key Accounts Manager for Process Equipment. In contrast, mechanical limit switches always require adjustment during installation and are actuated by an adjustable cam that is prone to needing re-adjustment during its service life. Unlike mechanical limit switches, F31 sensors will not fail over time due to metal fatigue. Additionally, these sensors do not require a bulky and costly metal enclosure to protect them from the environment and to keep unauthorized personnel from tampering with switch settings. F31 valve position sensors may be used on clockwise or counter-clockwise rotating actuators, or mounted onto a manual valve with an optional mounting bracket. Accuracy and repeatability are unaffected by the speed or frequency of the actuator. They are available in 2 and 3-wire DC models, and 4-wire AC/DC models. AS-Interface, Namur, direct solenoid valve connections, and cabled or terminal connections, are also available. F31 sensors are activated by metal targets on a companion “Puck” (Model BT65) that provides adjustment-free mounting directly to the actuator stem in less than five minutes with a single bolt. The puck also features a visual position indicator. Pepperl+Fuchs is a world leader in the design, manufacture and application of high quality factory and process automation products and services. Pepperl+Fuchs pioneered the development of proximity sensors 45 years ago, and has set the standard for innovation and quality ever since. |
