Differential Pressure Sensor - E8Y In one miniature package, the E8Y differential pressure sensor solves applications that previously required two individual sensors and a controller. It is an extremely sensitive and reliable controller with discrete outputs for direct connections to your PLC. A separate analog output makes the data available for charting. The E8Y puts intelligent control at the site, freeing up your control system for faster performance. Gauge Pressure Sensor - E8F2 Make your pick-and-place and object detection applications perform at peak consistency with the new E8F2 gauge pressure sensor. Its large LED face simultaneously displays an analog bar graph and digital pressure values so you can monitor all aspects of your application at a glance. These models also have two independent discrete outputs for quick connections to your control device, and an analog output that simplifies data collection. Choose either vacuum or pressure models to fit your application. 31 x 30 x 30 mm (1.22 x 1.18 x 1.18 in) * * * * * * * * * * 28 x 28 x 29 mm (1.10 x 1.10 x 1.14 in) Small size PSI models with 2 pressure ranges 1-touch programming for upper and lower limits Hysteresis mode (ideal for detection applications) Window modes (ideal for maintaining a pressure range) Digital and analog outputs NPN or PNP output types Manual or Automatic programming User defined normally open or normally closed configuration 3 different pressure ranges Programming Options Both the E8Y and E8F2 can be configured either normally open or normally closed. They also offer a choice of Hysteresis or Window mode and auto or manual programming. Manual Hysteresis Mode Normally Open Output Hysteresis Width ON OFF If you know the exact pressure settings of your application, simply enter the ON and OFF set values. The Hysteresis width is automatically set. Pressure Value OFF Set Value ON Set Value 2-Point Auto-Teaching Hysteresis Mode This method automatically sets Output the essential parameters based Hysteresis Width on production ON Midpoint between values. Use an Teach 1 & Teach 2 actual object to teach the ON OFF and OFF points, and the midPressure Value OFF point will be Point ON Point automatically Teach 1 Teach 2 Using actual object Using actual object set. Manual Window Mode Normally Open Output SET Normally Open These programming methods are ideal for detection applications. 1-Point Auto-Teaching Window Mode Normally Open The manual Window mode requires you to set the ON and OFF set values and the Hysteresis width. Hysteresis Width (set value) ON OFF Pressure Value OFF Set Value Output This is the ideal programming mode if you have a target pressure.
