TRADUCTOARE DE PRESIUNE
Traductoarele de presiune functioneaza pe baza sistemului cu 2 sau 3 fire si convertesc presiunea (semnal de intrare) in curent direct sau tensiune (semnal de iesire) proportional cu presiunea. Gama variata de modele oferta posibilitatea masurarii cu acuratete diferita a aproape tutoror presiunilor relative sau absolute.
Designul lor, capacitatea la incarcari mari si posiblitatea instalarii unitatilor in orice pozitie le permit sa aiba o gama larga de aplicatii.
D-400 series with piezoresistive or ceramic transducer behind its flush face diaphragm is especially suitable to contaminated liquids and for tanks with bottom measurement of pressure (level). The high temperature versions are able to be used up to 150 °C. Units in the pressure range of 0 … 40 bar operate up to 300 °C. Absolute pressure measurement in the range of over 0.1 bar is possible.
The standard pressure transmitting liquid of the sensors is silicone oil, but the units can also be ordered with a pressure transfering liquid suitable for food industry. Transmitters can be applied both in 2- and 3-wire systems.
APLICATII
Datorita dimensiunilor si greutatii reduse, poate fi instalat direct in bazine, conducte, instalatii, etc.
