How to Select a Temperature Sensor

admin2 — Tue, 17 Jan 2012 00:40:49 +0000

There are many variables to consider when selecting the right temperature sensor for your application, but there is a wide range of availability from which to choose a product too. When you boil (no pun intended) all the variables down, there are basically just 3 overall criteria that need to be considered when selecting a temp sensor: 1. Data Requirements, 2. Economic Considerations, and 3. Application Considerations. But within each of these criteria, there are a number of areas to be aware of.

This is an excellent report which covers the data requirements, economic considerations, and application factors that should be considered when selecting the right Temperature Sensor. DEE offers a Free Whitepaper Report that reviews the critical sub-criteria for each of these 3 key areas, and how to properly select your temperature sensor. Using these three key criteria will dramatically improve your efficiency and effectiveness in selecting the right temperature sensor for your application.

12 Mistakes to Avoid When Selecting Circuit Protection for Your Application

admin2 — Thu, 22 Dec 2011 00:03:10 +0000

Dee Electronics has made available a White Paper Report outlining the 12 biggest mistakes to avoid when selecting Circuit Protection or Circuit Breakers for your application.

It’s only a circuit breaker, right? Yet there is enough complexity and confusion when it comes to specifying circuit protection that many engineers are designing equipment with too little or too much protection. Under-protected circuits leave equipment vulnerable to damaging electrical surges. Over-protected circuits add cost and can lead to nuisance tripping. Like Goldilocks and the three bears, the goal is to specify circuit protection that is “just right”. There are many misconceptions when designing-in Circuit Protection, and we cover the 12 most common pitfalls for this white paper. It is our hope that by sharing this expertise, you will avoid these mistakes and protect your designs with “just right” circuit protection.

The Key Advantages of Snap Action Switch/Sensors

admin2 — Thu, 08 Dec 2011 22:43:03 +0000

When it comes to performance, snap action switch/sensor technology definitely has been field-proven. Its simple operating premise has survived decades of technological improvements and demanding environments. Why? Because it works. When choosing a switch for an application, snap action should unquestionably be considered. Besides its track record, the technology offers a long mechanical life. Of course, this varies by vendor, but generally snap action switches last longer than expected due to a simple, yet rugged design. The switches can be designed with various materials and casings, which allows for flexibility and customizability as well. Some switches are waterproof or completely sealed within the casing materials chosen. Snap action switches are not sensitive to most temperature fluctuations and electronic interference, and auxiliary power is not needed to run a switch. Depending on the application, it is important to understand the capabilities of snap action. DEE offers a FREE White Paper Report that discusses the basics of operation of snap action switches, the ideal types of measurement for snap action sensors, and the advantages of using snap zction technology in your application.

Find More Space in Your Control Panel: Tap Rules for Molded-Case Circuit Breakers: Adhering to UL Standard 508A, NEC Section 409

admin2 — Wed, 23 Nov 2011 12:45:55 +0000

Learn how to apply multiple branches and multi-wire terminals with circuit breakers in industrial control panels in accordance with Underwriters Laboratories (UL) standard 508A and the National Electrical Code (NEC), National Fire Protection Association (NFPA 70-2011). Molded-case circuit breakers are used for the main overcurrent protective device (OCPD) and the main disconnecting means for an industrial control panel, or as a main or feeder application. If branch circuits need to emanate from the main OCPD, this can be accomplished via a few different methods. DEE offers a short Free White Paper Report that covers this information.

The Key Criteria You Need to Use to Select Cabling for Your Application

admin2 — Tue, 25 Oct 2011 23:05:50 +0000

Cables are often the last component considered during system designs. In many situations, cables are really the system’s lifeline—if a cable goes down, the entire system can stop. For example, if the cable system ued for data transmission in a spacecraft fails, the communication between the craft and mission control could be lost. Cable reliability is based on both durability and signal integrity, and the ideal cable system should be engineered to last the life of the product in any environment.

DEE offers a free Whitepaper Report that discusses factors that affect wire/cable performance, cable life, types of cable choices, and applications issues. Also included is a nic cable selection checklist for an Engineer to use.

How to Determine a Panel’s SCCR Rating

admin2 — Thu, 13 Oct 2011 23:41:02 +0000

The determination of Short Circuit Current Ratings can appear to be a formidable task to complete if you are not familiar with the National Electrical Code® or the UL 508A Standard for Industrial Control Panels in the United States. However, by breaking the task down into systematic steps, the process can be much simpler to follow. Through upfront planning, an understanding of the Weakest Element SCCR determination method, and careful selection of Power Circuit components, a suitable assembly Short Circuit Current Rating can be achieved. This FREE White Paper Report offered by DEE steps through determining SCCR ratings to achieve compliance for SCCR marking, and the different methods of doing this.

Improve Your Liquid Level Sensing and Detection Applications

admin2 — Fri, 16 Sep 2011 20:29:52 +0000

Dee offers a free white paper report that identifies key issues experienced by manufacturers of equipment regarding handling and detection of liquids, with capacitive proximity sensors in particular. It examines concrete sensing/monitoring methods that will improve processes while guaranteeing reliable and dependable noninvasive liquid level detection. The trend towards more sophisticated equipment, which are expected to handle increasingly complex tasks, requires the most proven, repeatable and reliable sensing technologies available. Many factors make it especially difficult for machine/instrument builders to acquire essential real-time information about the machine or instrument’s state in a non-invasive manner. In most applications, it’s virtually impossible to place sensing devices directly in the fluid pathway. This report provides a review of dealing with challenging areas of liquid level detection and how capacitive sensing technology can solve those challenges.
