Top FAQs

Q: I have several requirements to meet in selecting a panel meter. How can I narrow my choice based on what I need?

Use Red Lion’s handy panel meter selector tool.

Q: What workstation display sizes are optimal?

Midsize displays (around 10″ to 15″) are popular. Smaller displays are impractical unless necessary. 17″ displays are too big for workstations that must fit a 19″ mount or other relatively compact footprint.

Q: What kinds of touch screen technologies are available?

Capacitive or resistive touch screens simply respond when an object changes the static condition of the glass (resistive requires more pressure because response is generated by compressing two layers together); the guided wave sets up a field that responds to the disturbance at the surface. Guided wave and resistive respond better when dirty, greasy environments are a factor, but may require the unit to be larger in order to accommodate the width of the circuitry around the LCD viewing area. Newer infrared optical technology is affordable and offers some advantages in the flexibility of design.

Q: How should displays be protected?

Users should use 0.125″ to 0.25″ tempered glass to protect the LCD display, depending upon duty. For LCD touch-screens, it is important to choose the appropriate technology for the application. Resistive touch-screens, when properly protected, are ideal for outdoor environments because they are unaffected by moisture, dust, etc., and respond to a gloved hand. Capacitive touch is generally superior for use in indoor environments, requiring more complex interactive screen controls because of generally higher resolution and accuracy and lighter force required to operate, reducing fatigue over time. Glass-on-glass technology offers resistance to wear and protection in extreme temperatures as well as resistance to UV deterioration.

Q: I’m reluctant to allow too much interface in the common work area. How can I limit certain functions to the proper personnel?

Software password control is one way. Another is to employ a mechanical key-type device or access panel that can only be opened by key personnel; through an access door, more functionality can be available such as full keyboard access to control software and programming or configuring of devices. Magnetic overlay templates are employed by some manufacturers to activate alternate keyboard functions.

Q: How can we effectively address the issues posed by a harsh environment?

First, look for low-power components (such as made for laptops) because heat generation is a critical problem. Look for components that are pre-tested for shock and vibration. Use rubber, foam, and other gaskets wherever possible to remove vibration peaks, which can reach multiple Gs in the industrial environment. Do not rely on outside air exchange for cooling; instead, radiate heat to the outside through heat sinks. Be sure your suppliers will carry components for the life cycle of the design. Review applicable ratings information to see if you should be getting third-party testing to ensure safety or continuous operation under your environmental conditions. Beta test. Finally, assess whether your in-house staff is really best employed, or has the proper experience, to handle this type of project. Check the costs and advantages of finding a good partner in development for what you need before you commit to doing this in-house.

Q: What’s the difference between point to point vs. point to multipoint wireless connections?

Point to point describes applications such as connecting two buildings together (this is also the scenario described when the term “bridging” is used). Point to multipoint describes an application where a central point connects to a lot of other points (a single building connecting to multiple buildings, or even multiple clients connecting to the same access point).

Q: What is Zone 1?

Hazardous area are divided into zones to indicate the probability of a hazardous mixture of gas (or dust) and air being present. Zone 1 is a place in which an explosive gas-air mixture is likely to occur in normal operation (>10 and less than 1000 hrs/annum).
