8692 Digital Electropneumatic Positioner

The compact positioner device Type 8692 is optimised for integrated mounting on the pneumatic actuators in the process valve series Type 23xx/2103 and is specially designed for the requirements of a hygienic process environment. The pilot air duct is integrated into the actuator without external piping. The easy operation and the selection of additional software functions are carried out either on a big graphic display with backlight and keypad or via the COMMUNICATOR. The positioner registers the valve position without deterioration via a contact-free, analogue position sensor. The integrated diagnostics function are used to monitor control valve operating conditions. Valve diagnostic messages via status signals are issued in accordance with NE107 (NAMUR) and recorded as historical entries. The housing is easy to clean and features proven IP protection and chemically resistant materials for use in hygienic processing in the food, beverage and pharmaceutical industries. Combined with Bürkert ELEMENT actuators, the pneumatic actuating system enables spring chamber aeration that avoids actuator chamber contamination from the environment.
