Series 52 2N1 ProxSensor valve status monitors from Bray Controls, Houston, TX, are now available in versions with AS-i, DeviceNet, or Profibus DP communications along with a solenoid drive. Each device incorporates 2 proximity sensors in one compact, self-contained, sealed enclosure. Features include local LED indicators; an optional valve position display; AC, PNP or NPN DC, or NAMUR DC units; adjustable targets so you can set both valve position signals at incremental angles before or on the fully open or fully closed positions; and imperviousness to vibration, moisture, and most chemical and corrosive agents. The device mounts directly to the company's pneumatic actuators, eliminating contamination buildup between sensor and actuator.
