Should You Use Current or Voltage in Analog Transducer Readings?
When choosing an analog measurement transducer for a variety of instrumentation monitoring applications including machine monitoring, quality assurance, and more, you will be given a choice of signal types. The most common signals for these transducers are either voltage (0-5 V dc, or 0-10 V dc) or current (generally 4-20 milliamps). Both types are low-cost and easy to find, and both have advantages and disadvantages depending on the environment in which they are being used. As a result, the Applications Specialists at CAS DataLoggers have put together this article to explore both the pros and cons of these two analog signals.
