Type 8692 positioners combine simply and reliably with Type 23xx/2103 process valve actuators, and are specially designed for the requirements of hygienic process environments, such as in food, beverage and pharmaceutical industries.
Functions are activated using push-buttons and DIP switches or a PC interface.
The control air channel is integrated in the actuator without external tubings. The easy handling and the selection of additional software functions are done either on a big graphic display with backlight and keypad or over a PC interface. The Positioner registers the valve position without deterioration through a contact-free, analog position sensor.
The control of single or double-acting actuators is done without internal air consumption. With integrated diagnostic functions operation conditions of the control valve can be monitored.
Through status signals, valve diagnostic messages are transmitted according to NAMUR NE107 and recorded as history entries.The position setpoint is set using the standard signal 4-20 mA. In addition, the enable can be controlled using the binary input and an optional position feedback can be integrated. Fieldbus communication via optional AS-Interface.
The housing is easy to clean and features proven IP protection and chemically resistant materials.
They meet the demands of plant washdown environments thanks to their compact design, materials used, external seals, and integrated control air supply to the actuator.
