Replace analog transducers with industry’s first configurable digital version

A company out of Cincinnati claims it is the first to develop and market configurable digital transducers, with owners of injection molding machines one of the most important groups of customer for the company. In comparison to analog ones, these digital transducers are said to improve accuracy and reliability, and reduce power consumption.

The developer and marketer of these digital transducers, Transducers Direct (Cincinnati, OH), says its TD1000/1004 Series Transducers can be a direct replacement for any currently used analog unit, but use time-to-digital technology to enable the above cited improvements. Built-in functionality eliminates the need for separate analog temperature and pressure switches.

According to Rob Matthes, president of Transducers Direct LLC, "This is a digital transducer that will very quickly obsolete other units. It is more accurate within a wider operating temperature range and has redundant sensor elements for added reliability. 

And our design enables it to be affordable without sacrificing features." The transducers are direct plug-and-play replacement for analog units, and have the same pin-to-pin configuration. A TD1000/1004 Series transducer turns a digital signal into an analog output that is fed directly into an industrial controller.

"Our tests have shown these digital units to be far less noisy than analog ones, which makes them less susceptible to electromagnetic interference (EMI)," added Matthes.  Matthes said the current consumption is low enough that, depending upon application and operating time, a four-to-eight year use life is projected using a coin cell battery as a power source for wireless transducer solutions.
