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.
What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
