The TD1000 is a revolutionary New Industrial Pressure
Transducer utilizing the change in "Time" instead of a change of voltage across
strain gauge sensing elements to sense pressure, an industry first, according
to the company. The TD1000 can also have a built-in programmable digital alarm
set-point for either pressure or temperature in conjunction to industrial
standard analog outputs, Industry First! The unit has built-in sensor
redundancy in case one element fails the transducer continues to run to
minimize machine down-time, Industry First! The TD1000 combines an IP69K
connection and a compensated range nearly matching the operating temperature
range along with high accuracy and low cost. With analog circuitry in
transducers/sensors, it is difficult to amplify a low level signal without also
amplifying the noise, as with strain gauges. Filters are required adding cost
and signal delays. By utilizing a TDC (Time to Digital Converter), internal
updates in the 100 micro-second range are realized providing higher accuracy
plus the inherent advantages of digital circuit design. Because of the
innovative design and very low power consumption it's ideal for wireless
applications and can run more than five years on a single coin-cell battery.
Redundant sensing elements are cost prohibited with analog designs but simple
and low cost with TDC designs. The significant difference with this transducer
is sensing the change of resistance with time instead of voltage change. By
very accurately measuring (in the pico-second range) the discharge of capacitors
across the sensing elements via a TDC (Time to Digital Converter) ASIC, keeps
the signal in the digital world until it goes through the D/A converter for the
final output to the outside world. By utilizing this technology/approach you
also have a transducer that its pressure range and output are fully
programmable, which reduces inventory costs, and provides a stable, high
accuracy signal without noise concerns typical with analog circuitry.
The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
The age of touch could soon come to an end. From smartphones and smartwatches, to home devices, to in-car infotainment systems, touch is no longer the primary user interface. Technology market leaders are driving a migration from touch to voice as a user interface.
Soft starter technology has become a way to mitigate startup stressors by moderating a motor’s voltage supply during the machine start-up phase, slowly ramping it up and effectively adjusting the machine’s load behavior to protect mechanical components.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
If you’re developing a product with lots of sensors and no access to the power grid, then you’ll want to take note of a Design News Continuing Education Center class, “Designing Low Power Systems Using Battery and Energy Harvesting Energy Sources."
