The Ametek Model 40 Pneumatic Pressure Controller is engineered to automatically position valves or other final control elements, ensuring that process pressure is maintained at the desired set point. This versatile controller is capable of managing any process variable transmitted as a pneumatic signal.
Key Features
- Control Modes: Offers a range of control modes, including 100% proportional, 200% proportional plus reset, and 300% proportional plus reset plus rate (PID), catering to processes with varying load changes.
- Environmental Compliance: Meets the EPA Quad Zero requirement with a bleed rate of less than 6 SCFH when operated on natural gas supply, aligning with environmental standards.
- Design and Usability: Features a large, easy-to-read dial for clear process indication. Field calibration is simplified through straightforward adjustments, and the standard proportional controller can be easily switched to on/off control action with an adjustable differential gap.
- Versatility: Available as an indicating pneumatic transmitter, it can be mounted close to the measurement point to transmit an air pressure signal proportional to the measured variable to other indicators, recorders, or controllers.
The Model 40 is a reliable solution for precise pressure control in various industrial applications, offering flexibility, accuracy, and dependability.
