steel die cast. The enclosure has a cover with a polymeric inspection window. As an alternative to the
polymeric material the window can be made from aluminium. The enclosure has an ingress protection
rating of IP66
See Annex for model code, thermal and electrical values.
3730-4/5
General - The positioners type 3730-41, 3730-51, 3730-45 and 3730-55 are communication-capable, bus-
powered field devices which are used to assign a valve position to a control signal. The bus interface
connection (bus-coupling) can be performed according to the FISCO-concept for both specifications,
Profibus PA and Foundation
flammable media are used as pneumatic auxiliary power. The equipment is intended for the application
inside the hazardous area.
The positioners type 3730-48 and 3730-58 are communication-capable, bus powered field devices which
are used to assign a valve position to a control signal. They are mounted onto levitation and slewing
actuators. Non-flammable media are used as pneumatic auxiliary power. The equipment is intended for
the application inside the hazardous area.
Construction - The Type TROVIS 3730-4_5 HART° Positioner mainly consists of the electronics part. The
parts are assembled in an enclosure made of aluminium die cast or stainless-steel die cast. The enclosure
has a cover with a polymeric inspection window. As an alternative to the polymeric material, the window
can be made from aluminium. The enclosure has an ingress protection rating of IP66
See Annex for model code, thermal and electrical values.
TROVIS 3793
General - The Type 3793 HART Positioner is a single or double acting positioner for attachment to
pneumatic control valves. The positioner ensures a pre-determined assignment of the valve position to the
input signal. It compares the input signal received from a control system to the travel or rotational angle of
the control value and issues a corresponding output signal pressure for the pneumatic actuator
Construction - The 3793 HART Transmitter Positioner consists of the electronic part and one or two
pneumatic modules. The parts are assembled in an enclosure made of aluminium die cast or stainless-
steel die cast. The enclosure has a cover with a polymeric inspection window. As an alternative to the
polymeric material the window can be made from aluminium. The enclosure has an ingress protection
rating of IP66
See Annex for model code, thermal and electrical values.
