Process Control

Type 1067 PID controller/positioner is one of three recent devices from Burkert for process control applications. The other two are the Type 8630 TOP control system and Type 8365 process controller/positioner.

Valve positioners and actuators from Burkert include three devices for improved safety in process control applications. They include Type 1067 PID controller/positioner, Type 8630 Top control system, and Type 8365 process controller/positioner.

Type 1067 PID controller/positioner is a zero-bleed device compatible with nearly any rising stem or quarter-turn valve/actuator used for process control. Valve stem-mounted potentiometer provides precise valve position data for Type 1067 microprocessor-driven electronics. Choice to operate as a PID controller or positioning device is set internally. It can be adjusted through the integral display panel or sent remotely via common current.

Type 8630 Top control system—PID controller or positioner for the Burkert line of diaphragm and globe-style valves—is intended especially for process applications. It can take 4-20 mA, PT100, or pulse input directly from a sensor. Self-tune function determines the proper PID valves for optimum system control. Setpoint modulator prevents undue oscillation while running the Ziegler/Nichols-based program.

Type 8635 process controller/positioner is intended for 20-gauge wire and intrinsically safe control application and is used in conjunction with pneumatically actuated process valves. Microprocessor controlled unit automatically calibrates itself to the travel of the attached valve. A 4-20 mA input signal transmits the unit's control signal while simultaneously supplying the device with power. It is designed for use in intrinsically safe environments or where a low-power, two-wire control device is required.
