  • Water sensor moves from basic research to promising businessBy Krishna RamanujanLindsay France/University PhotographyCornell-developed water sensor and probe that inserts into the stem or trunk of a plant.A water sensor technology that began as basic research at Cornell is blooming into a business that fills a vital need for grape, nut, apple and other growers.While current water sensing too...
  • A wireless network of sensors aimed at preventing explosions in mines is an innovation of worldwide significance that is being developed by a Norwegian-African cooperative project.A Norwegian-African cooperative project aims to improve safety conditions for miners. The project initially targets the South African mining industry, but if it is successful, its results could also be of inter...
  • A pressure transmitter or pressure sensor is a device that measures pressure in a liquid, fluid, or gas. Pressure transmitters are commonly used to measure pressure inside of industrial machinery in order to alert the user before a catastrophe occurs. They have many different uses, most of which are industrial or automotive in nature. A pressure transmitter is easily recognized as it is ...
  • A piezoelectric transducer is a device that converts electricity into mechanical forces or vibrations. Although piezoelectric transducers have other uses, ultrasonic devices require them. Piezoelectric transducers usually converts electricity into vibrations and vibrations into electricity, although this is not always the case. They rely on two phenomena known as “electrostriction” and...
  • Although cities have a vital role in minimizing the emission of greenhouse gases to tackle climate change, the direct measurement of the emissions has always been difficult.Mobile sensors were attached to car-share vehicles in Vancouver. Credit: University of British ColumbiaResearchers from the UBC have now developed an innovative technique to measure the emission of carbon dioxide, consi...
  • What is a Temperature Transmitter?The thermocouple or RTD signal is converted to a 4 - 20 mA output signal using a temperature transmitter, which is considered to be the ideal solution for a number of remote temperature measurement applications. In comparison to conventional temperature measuring devices, temperature transmitters have definite advantages but must be selected with caution...
  • Traffic can be dangerous, but the risks of congested highways may go beyond road rage and car accidents.Traffic-related air pollution (TRAP) presents a significant health risk, said Patrick H. Ryan, Ph.D., an associate professor of Pediatrics and Environmental Health Division of Biostatistics and Epidemiology at Cincinnati Children’s Hospital Medical Center, University of Cincinnati.“The e...
  • What is a Bourdon Tube Mar 20, 2017

    Bourdon Tubes are known for its very high range of differential pressure measurement in the range of almost 100,000 psi (700 MPa). It is an elastic type pressure transducer.The device was invented by Eugene Bourdon in the year 1849. The basic idea behind the device is that, cross-sectional tubing when deformed in any way will tend to regain its circular form under the action of pressure. The...
  • A differential pressure transmitter works by sensing the difference between two different ports and then producing a signal that corresponds to a certain range of calibrated pressures. Usually this set of functions requires that the differential pressure transmitter be built with two different cases. One of these cases holds the pressure sensing element, while the other houses the elec...

  • Technical Tips/FAQ What is the difference between differential, gauge pressure and absolute pressure?Differential pressure is the difference in pressure between two sources. If one source is 5 psi and the other is 3 psi, the differential pressure is 2 psi. A 4-20ma differential pressure transmitter with a range of 0-4 psi would read half of the scale which would be 12 ma.Gauge pressure is...
