FT — FasTrak
FasTrak is a smart positioner and its has a high-capacity, high-precision digital-pneumatic valve controller that replaces a conventional positioner. It has an excellent dynamic performance and high flow (Cv = 2).
His configuration and calibration is made through Hart device or by self calibration. FasTrak is compatible with double and single acting actuators, with or without spring, piston or diaphragm.
Tight shut off and travel limit position are independently adjustable up to 50% of stroke to open and to stroke.
The pressure shut off to open and to close is independently adjustable.
Positioner’s parameters can be easily selected from a Remote Control device.
This product has two digital inputs and outputs. The first ones are used to fully open or fully close the actuator. The second ones are used as virtual limit switch or to indicate position error or low pressure. The power/signal fail position can be mechanically configured.
