Increasingly, outputs using sensor bus protocols are being offered. Most position transducers require 50 V or less, and some are self-powered. Finally, for fast-moving applications, determine the maximum velocity or acceleration that needs to be monitored. Ensure that your data-acquisition or control system has an adequate sampling rate to record the resulting datastream. Photo 1 Cable position transducers provide extended ranges in small sizes.
Flexible cable allows for easy installation.
Check Your Requirements Now that you're aware of the key parameters, you need to determine which ones are relevant to your application and of these relevant parameters, which are most critical. If you don't prioritize your requirements, it's going to be difficult to make a selection decision. You may come to the conclusion that there is no transducer that can meet your needs. This may be true, but it's more likely that your requirements are too stringent and that you need to make a tradeoff to arrive at the optimum selection. He was adamant that all three specifications be met.
