Simmonds Precision Aircraft Systems. ... One of the most successful multimode fiber optic sensors to date has been the Faraday sensor. This type of device has been used to detect rotational speed, torque, proximity and other parameters. When in a reflective configuration, the transducer element has consisted of a thin Faraday film between a polarizer and a mirror. In this paper, it is shown that enhanced performance of the sensor results when the polarizing element is removed from the transducer.  2, fiche 1, Anglais, - transducer%20element

Phase angle transducers provide a signal which is linearly proportional to the phase angle between a voltage and a current in a power system. This type of transducer is often called a power factor transducer, which is technically incorrect as power factor is proportional to the cosine of the phase angle and as such is non linear.  1, fiche 3, Anglais, - phase%20angle%20transducer

La mesure de la force d'un astronaute est l'un des paramètres fondamentaux utilisés pour évaluer ses performances physiques et l'effet de l'apesanteur pendant les missions spatiales prolongées. Sous contrat de l'Agence spatiale européenne, une société a développé un système pour mesurer la force de la main et celle du pouce, utilisé lors d'expériences embarquées. Le système se compose d'un dynamomètre de poigne de la main (HGD) et d'un dynamomètre de force de pincement (PFD) ainsi que d'une unité de connexion pour raccorder l'équipement à l'alimentation (28Vcc) et à un ordinateur.  1, fiche 7, Français, - dynamom%C3%A8tre%20de%20force%20de%20pincement

When specifying a mass flow control system, the first consideration is whether the process will take place at constant system pressure, constant throughput, and/or predetermined gas flow ratio. Another important consideration is whether system control will be automatic(microprocessor) or manual(setpoint potentiometers).... There are three major state-of-the-art systems that can be identified. The first uses a flowmeter(s)... as the primary transducer(s) to monitor mass flow. Using this format, a signal is compared in control circuitry to a setpoint signal. This generates an error voltage which is used to drive a valve, thus continuously controlling the flow. The second major type of system uses a pressure transducer as the primary sensing element. System pressure is held either constant or varied at a predetermined rate by controlling the mass flow rate of process gases. This leads to a third type of system that slaves valves and flowmeters to the primary sensing.  1, fiche 8, Anglais, - mass%20flow%20controller
