Emerson 4195KBE Controller

Product Overview

The Emerson 4195KBE is a Fisher™ 4195KBE Gauge Pressure Indicating Controller. It is a pneumatic pressure controller designed for industrial process control applications. The controller measures process pressure, compares it with the operator-adjusted set point, and outputs a pneumatic control signal to regulate process equipment.

The 4195K series controllers are widely used where reliable pressure indication, control, and monitoring are required, especially in process industries.
