Burkert's PID Controller/Positioner
Type 1067 PID Controller/Positioner is compatible with virtually any rising stem or quarter-turn valve/actuator used for process control. The unit consists of two components: the valve stem position pickup and a microprocessor-driven pneumatic controller. The control or position setpoint can be adjusted via the integral display panel or sent remotely via common current (020mA, 420mA) or voltage (010 VDC) signals. Unlike traditional I/Ps and positioning devices, the Type 1067 is a "no air-bleed device." In a steady-state condition, air consumption is zero.
