How to Choose a Rotary Encoder for an Automation Project

If you need to purchase an encoder but are unsure which type is best, get assistance from a reputable source. That way, you’ll receive accurate and reliable information on the count, direction, speed, and position capabilities based on your specific application. For automation projects, many people prefer optical rotary encoders.

Before you buy a rotary encoder, take time to learn how the two best types differ and the benefits they provide.

Optical Vs. Magnetic Rotary Encoder

Before going over the buying tips provided, look at the brief rundown between these two rotary types.

Magnetic

With a spinning magnetized disc composed of alternating poles and either a magneto-resistive or half-effect sensor, the magnetic rotary encoder detects changes within magnetic flux fields. Since it’s rugged and handles both vibration and shock with ease, it’s a good option for your automation project.

Optical

Compared to the magnetic type, optical rotary encoders boast higher resolution and accuracy. Along with a glass or plastic disc, this device consists of an LED light and several slots that alternate between opaque and transparent. If you want an encoder that can detect motion and provide accurate information, this is likely the one you want.

Helpful Tips When You’re Ready to Buy a Rotary Encoder

Both an optical and magnetic rotary encoder affect motor performance. So, have one of your company’s engineers look at the various properties of each, in particular, those listed below.

  • Audible noise (the quieter, the better)
  • Bandwidth (this determines the response of the drive command signal)
  • Positioning accuracy
  • Power loss
  • Speed stability

To better understand the importance of this, whether you choose an optical or magnetic rotary encoder, consider a few examples of why these properties matter.

Position Accuracy

Unfortunately, a magnetic rotary encoder has significant limitations. Typically, the position accuracy of this device falls within a range of ~ ±500”, which equates to 16,384 positions per revolution. In comparison, the optical device has a much greater accuracy of ~ ±280”, resulting in 131,072 positions per revolution.

If accurate positioning is critical to your automation project, the optical encoder wins hands down.

Speed Stability

This is another important factor to look at before you buy a rotary encoder. Along with the number of measuring steps per revolution, the engineer should focus on signal quality. There’s a reason for this. The way an encoder achieves the resolution needed is by having interpolated scanning signals. So, high quality is essential.

Bandwidth

Finally, there’s bandwidth as it relates to the control reliability and command response. To ensure optimal performance, whether an optical or magnetic rotary encoder, the engineer should look at two specific things. First is the rigidity of the coupling that goes between the encoder shaft and motor shaft. The second has to do with mounting. If not done properly, that can cause long-term resonant vibration.

How To Eliminate Common HVAC Odors

Most homeowners turn towards the air conditioner unit in their home to keep their pets and family comfortable when the summer starts to heat up. Just like any other appliance in your house, HVAC systems will also emit some terrible and strange odors. Most homeowners who own HVAC systems do not know why their units are emitting such strong odors.  

If you are one of them, then you need to realize that the main reason behind the strange odors from the HVAC system can range from potentially dangerous to innocuous. However, it is best to reach out to professional HVAC repair NYCtechnicians if strange odors are coming out of your HVAC system. Here are some of the common HVAC odors that you might encounter and a guide on what causes them and how to prevent the issue.  

A Musty Odor  

If there is a musty odor coming out from the HVAC unit, then mold will be most likely the common culprit behind the issue. The AC unit in your home will be working a lot harder during the summer and the moisture that is produced will get collected in the ductwork or the unit. Mold requires moisture, air, and warmth to grow, which makes your HVAC system an ideal place for it to grow.  

You should immediately get in touch with an HVAC repair NYC technician if there is a musty odor. The technician will be easily able to identify the root cause of the issue and they will also help you resolve it as fast as possible. The solution can be something as simple as cleaning the ducts or replacing the air filter.  

Decaying Garbage Odor  

Another common odor, which might come out of the HVAC unit in your home will remind you of decaying or stinky garbage. This type of odor occurs when a rodent or a small animal has been living inside the HVAC unit. Several animals often seek refuge in the ductwork of HVAC units.  

If you allow these animals to continue living inside the HVAC unit in your home, then they will build a nest and may reproduce gradually. The garbage smell that comes out of the HVAC system could be caused either by the fecal matter, nest, or the decaying body of the animal.  

If you are able to notice such an unpleasant odor, then it is best to contact an experienced HVAC repair NYC technician immediately. The technicians will resolve the issue, check if there are any holes in the ductwork, and ensure that no animals will be able to reenter the HVAC unit.  

Burning Electrical Or Smoke Odor 

In some cases, you might be able to notice an odor, which will be similar to a burning electrical odor. You will need to act quickly if there is such an odor coming out of the HVAC system. There are several electrical components within the HVAC system and if one of them is overheating or damaged, then it might result in a fire.  

The first thing you should do when you notice such an odor is to turn off the HVAC unit. If the odor near the components of your HVAC systems seems stronger, then you should immediately reach out to an HVAC repair NYC technician.  

It is best not to try and fix the situation on your own, as it may destroy the HVAC unit or you might end up getting hurt. All you need to do is to wait for the HVAC repair technicians to arrive, as they will be able to resolve the issue with ease.

What are the top Web Development Technologies and Frameworks for 2021?

What are the top Web Development Company Technologies and Frameworks for 2021? There are many new technologies coming out every year, but not all of them will be around by 2021. The following list of technologies and frameworks will continue to be popular in the coming years. Most of them are still very new, which makes it difficult to predict what will happen with them by 2021, but there is enough activity on GitHub to indicate that they are important technologies that deserve more attention than they currently receive.

1) Ember.js

A framework that allows you to create single-page web applications with a scalable, agile architecture. It’s known for its speed, powerful features, and flexibility. In 2016 it was considered one of the most popular JavaScript frameworks on Stack Overflow—an impressive feat given its relative newness compared to some of its more mature counterparts. One of Ember’s biggest benefits is that it focuses on a front-end rendering engine rather than a back-end one.

 

2) React.js

React.js is a JavaScript library developed by Facebook to help with building user interfaces. Since its launch in 2013, it has been heavily adopted by developers across different industries. It’s open source, cross-platform, modular, scalable and above all fast. We are best in react native development company. 

 

3) Angular.js

Node.js is an open-source, cross-platform JavaScript runtime environment for developing server-side applications. Node.js is used by tens of thousands of developers in more than 200 countries around the world to develop powerful web applications that run on both client-side and server-side processes. Tagline infotech is the best angular js development company in Usa. 

 

4) Backbone.js

A server-side runtime environment that executes JavaScript code outside of a browser, Node.js is an open-source platform that allows programmers to run multiple processes in parallel. The framework utilizes an event-driven, non-blocking I/O model, allowing it to efficiently handle real-time web applications.

 

5) Node.js

Although it’s been around since 2009, Node.js is only now starting to reach enterprise-level maturity. Built on Google’s V8 JavaScript engine, Node allows developers to write server-side applications in JavaScript (JS), which can be used to manipulate data on a web page using AJAX—or create entire browser apps without refreshing a page. It was originally developed as an open source project by Ryan Dahl back in 2009, who was working at Joyent at that time.
