EP500 Advanced ATEX Electropneumatic Positioner
The EP500 is a 2 wire loop powered positioner requiring a 4-20 mA control signal, and is designed for use with linear pneumatic valve actuators. The positioner compares the electrical signal from a controller with the actual valve position and varies a pneumatic output signal to the actuator accordingly.

600 Series pressure, temperature or other pneumatic-electric signal controllers
Series 600 indicating pneumatic controllers are instruments designed for directly measuring a temperature or a pressure which is indicated by a pointer on a segmental graduated scale 100mm wide. At the same time the measured variable is automatically controlled by a pneumatic control unit which in turns operates a control valve or any other pneumatic device. Indicating controlling instruments with a receiving element for 3 to 15 psi (or 0.2 to 1 bar) pneumatic signal from a remote transmitter of any variable are also available.

5500 and 8500 Series differential pressure and level pneumatic transmitters
Series 5500 and 8500 transmitters are blind instruments working on force balance principle and designed for directly measuring differential pressures or levels and converting them into a linear 3 to 15 psi or 0.2 to 1 bar pneumatic signal. A high capacity, built-in amplifying relay allows signal transmission, even over considerable distance, with minimum air consumption. The transmitted signal is directly and strictly proportional to the measured value with remarkable accuracy, repeatbility and sensitivity due to the characteristic force-balance principle, without any moving part and, consequently, no friction or hysteresis and thanks to the feedback device of hte transmitting unit. Series 5500 transmitters are mostly used transmit instantaneous flow rate values of a fluid measured according to the differential pressure across orifice plates or Venturi tubes in process pipe network. They are also used for level measurement when it is impossible to install series 8500 transmitters directly on the tank.

EP500 Advanced Posizionatori elettropneumatici classificati ATEX Istruzioni di installazione e manutenzione
Il posizionatore EP500 2 è un dispositivo con circuito a due fili alimentato da un segnale di controllo 4-20 mA, ed è progettato perl'uso con attuatori pneumatici lineari e rotativi*. Il posizionatore confronta il segnale elettrico in ingresso la posizione effettiva della valvola, e di conseguenza varia il segnale di uscita pneumatica all'attuatore.

Posizionatori elettropneumatici EP5 standard e ISP5 ATEX
Il posizionatore EP 5 funziona secondo il principio delI’equilibrio di forze e quindi con attriti ridottissimi ed in assenza di isteresi. Esso garantisce una esatta proporzionalità tra la corsa dello stelo del servomotore pneumatico ed il valore elettrico di controllo proveniente dal regolatore pilota.
