Under Pressure – The Pressure Transducer
Pressure Transducers In industry, we deal extensively with pressure. We do in our day-to-day lives as well. For decades, many buildings had a barometer, a pressure sensor, to provide information about weather patterns. Small changes in atmospheric pressure can have a massive effect on whether the sun shines, or if we are covered in rain.…

Accelerometers
Accelerometers In the field Instrumentation and Test, we are often forced to use proxies. We can’t measure what we need to know, either because the technology to do it does not exist or because it would be impractical to do so. When situations like this arise, we need to find something else we can measure…

Volts or Amps – the crucial question.
Volts or Amps In a past Transducer Thursday we looked at Galvanometers, in an upcoming article we’ll look at digital voltmeters. Both have been used to create read outs from sensor data. That therefore leads to a question, what do we want transducers to output? A current variant signal or a voltage variant signal? In…

Magmeters
Magmeter – Magnetic Flow Metres How do you measure flow through a pipe? It’s a trickeier problem than it initially sounds. It’s also a question with many answers. Many approaches centre around pressure transducers measuring total pressure and static pressure to then infer dynamic pressure and therefore fluid velocity. Although this means that the density…
