Type 8635 Smart ElectroPneumatic Positioner Side Control

Brand: Burkert Fluid Control Systems
Does not ship to Virginia, United States

The Side Control Positioner Type 8635 is an electro pneumatic positioner for pneumatically actuated process valves with linear or part turn actuators. It is executed in two conductor technology.

Signal processing, control and actuation of the internal positioning system are accomplished with microprocessor-controlled electronics. The software function Auto tune implemented therein enables automatic adaptation of the positioner to the control valve in use.

The positioner is parametrized and operated comfortably via three operating keys and a plain-text display. It is possible to set up a decentralized control system if a process controller with PID characteristics is used.

As an option, the Side Control Positioner Type 8635 can be supplied with approval for use in the Ex area (Zone 1) according to ATEX. Because of its compact and robust design, the housing is suitable for use in chemical and process engineering.
