Industrial Sensors Offer More Connectivity Options

Big data, medium data, small data. No matter the magnitude of the amount of machine or process data needed in manufacturing operations these days, sensor suppliers of every ilk are providing more network connectivity possibilities with their devices to help report operating and/or condition status to other segments of the company, as well as enable more direct machine control feedback.

"The growing popularity of industrial networks has heavily influenced the expansion of our rotary encoder line," reports Bob Alesio, AMCI director of sales and marketing. "Our most popular shaft encoders now include an Ethernet, DeviceNet or Profibus interface."

Control Design's audience surveys regarding industrial sensor use seem to back that up. In 2008, 78% of respondents reported that their deployed sensors were hardwired. December 2013's survey pegs that number at 53% now. Nearly 15% of respondents noted using IO-Link, a solution that wasn't even asked about in 2008, since its North American visibility was pretty low at that point. Basic serial EIA232/422/485 was used by 23% of respondents in 2008. This latest survey puts that use at 10% at present.

What hasn't yet changed much is the percent of survey respondents who say they use wireless sensing. Only about 30% report using them, a number that's been largely constant since 2008.

  Compute the Power    
APN Series power-monitoring sensor measures three phases of current and voltage, and computes 14 values to track power use in the RS485 Modbus RTU format. To measure watts in an ac circuit, the supplied voltage is compared with the current and indicates whether the current peaks before the voltage (leading power factor in a mostly reactive circuit) or the current peaks after the voltage (lagging power factor in a more inductive circuit). It can be configured to accept standard 5-A current transformer inputs or sensors producing 333 mVac proportional to the ac current of the circuit.
