Burkert’s 8792/8793 Sidecontrol positioners/process controllers are designed for flexible mounting onto linear and rotary actuators.

The Sidecontrollers offer excellent control accuracy and outstanding dynamic properties in positioning and decentralised process-control tasks.

They are suitable for a range of applications in sectors such as hygienic processing, water treatment, steam and gas handling, typically in the control of auxiliary processes – water, steam, air, heating and cooling.

The Sidecontrol 8792 intelligent positioner unit can be attached directly to an actuator, used as a remote mounted version or installed in a separately controlled enclosure.

Due to its compact and robust IP65/IP67-rated aluminium housing, the Sidecontrol 8792 is suited for use under tough ambient conditions and in Atex zones 2/22.

In addition, when configured as a process controller (type 8793) with automatic process value evaluation (such as temperature, pressure, filling level and flow rate) and automated parameterisation, the device is suitable for decentralised process control with optional simultaneous feedback to the plant-control level.

The 8792 employs the latest three-wire technology, said to significantly reduce cost compared with comparable devices based on three-wire technology.

The positioner’s wide control pressure range of 1.4 to 7 bar and the high air-flow range of 7 to 100Nl/min or 150Nl/min mean the Sidecontrol 8792 is extremely versatile.

The controller consumes no control air once in its steady position and can be easily operated using a large backlit graphic display.

The menu control of the Sidecontrol unit is operated through an intuitive four-key panel.

Sebastian Kundel, segment manager for hygienic processing at Burkert, said: ’In order to standardise and simplify processes for the operator, the concept is the same as that of Burkert’s digital 8692 electro-pneumatic positioner.

’End users of Sidecontrol 8792/8793 units connected to control actuators with IEC or VDI/VDE interfaces and Topcontrol 8692/8693 devices for use on Burkert control valves can thus use the same control logic for both types of controllers.

’This makes day-to-day operation much more efficient.’ Also aiding ease of use of the 8792/93 is a new version of Burkert’s Processtune function.

This allows easy, fast and reliable recognition of the control-loop type and selection of the suitable controller type with optimised parameters.

Initially Burkert launched the standard version of the Sidecontrol 8792, for IEC534-6/VDI/VDE 3845 (NAMUR) adaptions, as well as a version with Profibus DPV1 communications.

These will be followed later by units with Devicenet communications, a remote version for externally connected position sensors and a low-cost basic version without display for low-cost OEM applications.

The Sidecontrol actuators are suitable for both double-acting and single-acting linear and rotary actuators.

Offering the advantage of operating from a low-voltage (24V) supply, the 8792 works with industry-standard signal inputs and outputs: 4-20mA/0-5-10V plus binary I/O and offers Profibus DPV1 communications.

End-position detection on the unit is by means of limit switches (or the integrated displacement measuring system) with mechanical position indication also an option.

The 8793 process-controller version also has 4-20mA input, a PT 100 or frequency signal for the process-value input in closed-loop control applications.

In common with the 8792, it has an RS232 port for software updates and parameterisation.
