TROVIS 3793 Positioners

|   Products

The positioners use proven mounting kits and have a modular design.

High air capacities and variable outputs, e.g. double-acting control, can be achieved by using exchangeable pneumatic modules that can be retrofitted. Optional additional functions, such as limit switches, position feedback or binary inputs and outputs, can be added to the positioner on site as option modules. This allows positioners to be easily adapted to customer requirements at any time.

Extensive diagnostics, communication over HART® protocol, ease of operation with a multilingual plain-text display, and a protected non-contact sensor system contribute to making the positioner a first-rate device.
