4 Factors To Consider When Selecting Digital Encoders For Harsh Environments

When selecting a digital encoder for challenging environments, consider the environmental stressors, the type of sensing mechanism, vibration testing compliance and hazardous location certification. In this blog, Walker Machinery, a leading distributor of digital encoders such as linear encoders, rotary encoders and DRO systems in Milton, Ontario, explores these factors in detail.

How To Choose Encoders For Challenging Conditions?

Consider Environmental Stressors

What is the main environmental stressor leading to the challenging conditions? Is it high pressure, temperature, or the way the machines are washed down, presence of oil or lubricants, presence of dust or corrosive chemicals? Depending on the stressor, there are different types of digital encoders with varying IP ratings to consider. 
 

Type Of Sensing Mechanism

The next step is deciding the type of sensing mechanism. For instance, if the environment is relatively clean and accuracy is vital, then absolute optical encoders can be considered. However, if there is dust, moisture or shock, it is better to opt for magnetic encoders as they can tackle these stressors.
 

Vibration Testing Compliance

Are the digital encoders to be exposed to a lot of vibrations or shocks? Make sure to choose encoders which are tested for shocks and vibrations. Otherwise, inaccurate readings might become commonplace, leading to major errors.
 

Hazardous Location Certification

Finally, for really hazardous and explosive conditions, such as those seen in the oil and gas sector, there is also a need for special hazard location certification that also specifies the temperature class of the encoder. 
 

Conclusion

In summary, all the 4 factors mentioned above become vital when considering digital encoders, such as linear or rotary encoders, for challenging or hazardous conditions.

FAQs:

Why is IP rating important for digital encoders?

IP rating is important for digital encoders as it informs the user about the type of protection it offers, such as dust or moisture.

How to choose encoders on the basis of position feedback?

Based on position feedback, the options to choose from include absolute and incremental encoders.
