  2. Resistance thermometer - Wikipedia

    en.wikipedia.org/wiki/Resistance_thermometer

    By far the most common devices used in industry have a nominal resistance of 100 ohms at 0 °C and are called Pt100 sensors ("Pt" is the symbol for platinum, "100" for the resistance in ohms at 0 °C). It is also possible to get Pt1000 sensors, where 1000 is for the resistance in ohms at 0 °C.

  3. Particle velocity probe - Wikipedia

    en.wikipedia.org/wiki/Particle_velocity_probe

    The particle velocity transducer is called the Microflown. The second particle velocity transducer is manufactured by Weles Acoustics. Both commercially available solutions share a similar transduction principle. The Microflown sensor is a MEMS based transducer able to directly measure acoustic particle velocity.

  5. Potentiometric sensor - Wikipedia

    en.wikipedia.org/wiki/Potentiometric_sensor

    Potentiometric solid state gas sensors have been generally classified into three broad groups. Type I sensors have an electrolyte containing mobile ions of the chemical species in the gas phase that it is monitoring. The commercial product, YSZ oxygen sensor, [1] is an example of type I.

  6. Ultrasonic transducer - Wikipedia

    en.wikipedia.org/wiki/Ultrasonic_transducer

    A curvilinear array ultrasonic transducer for use in medical ultrasonography Inside construction of a Philips C5-2 128 element curved array ultrasound sensor. Ultrasonic transducers and ultrasonic sensors are devices that generate or sense ultrasound energy. They can be divided into three broad categories: transmitters, receivers and transceivers.

  7. Current sensing - Wikipedia

    en.wikipedia.org/wiki/Current_sensing

    Fluxgate technology principle. Fluxgate sensors or saturable inductor current sensors work on the same measurement principle as Hall-effect-based current sensors: the magnetic field created by the primary current to be measured is detected by a specific sensing element. The design of the saturable inductor current sensor is similar to that of a ...

  8. Distributed temperature sensing - Wikipedia

    en.wikipedia.org/wiki/Distributed_temperature...

    Distributed temperature sensing systems (DTS) are optoelectronic devices which measure temperatures by means of optical fibres functioning as linear sensors. Temperatures are recorded along the optical sensor cable, thus not at points, but as a continuous profile. A high accuracy of temperature determination is achieved over great distances.

  9. Catalytic bead sensor - Wikipedia

    en.wikipedia.org/wiki/Catalytic_bead_sensor

    The catalytic bead sensor MSA 94150 The catalytic bead sensor consists of two coils of fine platinum wire each embedded in a bead of alumina, connected electrically in a Wheatstone bridge circuit. One of the pellistors is impregnated with a special catalyst which promotes oxidation whilst the other is treated to inhibit oxidation.
