Carbon Potential Controller
MAXWELL SEMI AUTOMATIC CP CONTROLLER
MODEL: MAX-CPC-SA-V1.0
Maxwell CP Controllers are engineered with a high-speed STM microcontroller and a precision Analog-to-Digital Converter (ADC) to deliver highly accurate, stable, and reliable readings from oxygen probes. A key advantage of the latest Maxwell CP Controllers is their high input impedance design, which minimizes signal loading on the oxygen probe. This preserves signal integrity and enables precise millivolt measurements, especially in low-signal conditions, resulting in improved measurement stability, faster response times, and exceptional reliability in demanding heat treatment applications.
The controller provides precise regulation of carburizing fluids while continuously calculating Carbon Potential (CP) throughout the metal hardening process, ensuring consistent metallurgical results and enhanced process control. Designed for long-term operational stability, Maxwell CP Controllers are field-proven to maintain calibration accuracy over extended periods. Under normal operating conditions, they require minimal recalibration, helping reduce maintenance efforts, minimize downtime, and improve overall production efficiency.

MAXWELL FULLY AUTOMATIC CP CONTROLLER
MODEL: MAX-CPC-FA-V2.0
Maxwell CP Controllers are equipped with a high-speed STM microcontroller and a precision Analog-to-Digital Converter (ADC) for oxygen probe measurement, delivering exceptional accuracy, stability, and reliable process control. The system ensures ±1°C temperature accuracy while providing precise Carbon Potential (CP) control with integrated heater management for consistent heat treatment performance.
A key highlight of the latest Maxwell CP Controllers is their high input impedance design, which minimizes loading on the oxygen probe signal. This preserves signal integrity, enables precise millivolt measurement, and delivers outstanding stability and repeatability, particularly in demanding low-signal furnace environments. The controller accurately regulates both carburizing fluid and heater output, maintaining optimum temperature and Carbon Potential throughout the carburizing, diffusion, and soaking stages of the heat treatment process.
For advanced industrial automation, the controller supports RS-485 Modbus communication for seamless SCADA and PLC integration, 4–20 mA analog output for reliable signal transmission, and Thyristor (SCR) control for precise heater regulation. Designed for long-term operational stability, Maxwell CP Controllers maintain calibration integrity over extended periods, eliminating the need for frequent recalibration under normal operating conditions while reducing maintenance costs and production downtime.
