Ellis/Kuhnke Controls Pneumatic Indicators (NF Series)

The NF Series Visual Pressure Indicator is designed to monitor air pressure within a pneumatic system. It provides a visual cue through a color change to indicate the presence or absence of pressure. 

Options for Pneumatic Indicators

• Two-Color Visual Indication: The indicator has a ball or a similar visual element that changes color based on the air pressure condition. The specific colors available for indication depend on the model, as detailed in the product's catalog.
• Dual Modes of Operation:
  • Spring Return Mode: The indicator uses a spring mechanism in this mode. When air pressure is present, the indicator changes to one color (typically showing pressure is present). Once the pressure is no longer present, the spring mechanism returns the indicator to its original color (indicating no pressure).
  • Maintained Switch Position Mode: This mode requires a second port. The indicator changes color when air pressure is applied and remains in this changed state even after the initial pressure is removed. It returns to its original color when a second pressure signal is applied through the second port. This feature allows for tracking the presence of pressure and sequences or cycles of pressure application and removal.
• Visual Pneumatic Indicator Design Features: 
  • Oil Tight Panel Mounting: The indicator is designed to be mounted on a panel, such as a control board, and is resistant to oil, ensuring durability and reliability in industrial environments.
  • Extended Lens and Ball Design: The design of the lenses and the ball indicator extend beyond the panel's surface. This makes it easier to see the indicator's status (color and position) from various angles, not just directly in front. This feature is particularly useful in busy or cramped settings where direct line-of-sight to the panel is not always possible.

Overall, the NF Series Visual Pneumatic Indicator is an effective tool for visually monitoring the status of pneumatic systems. It enhances operational safety and efficiency by providing clear and immediate feedback about the system's pressure status.
