1650CC

PID Carbon controller dual loop, 1/8 DIN

MAIN FEATURES

• Dual loop PID Carbon Controller
• Zirconia probe input
• Aux analog input configurable temocouple, linear value

Overview

PID controller and measurement of carbon potential in metal heat treatment applications.
The direct connection of the zirconium oxide probes, the efficient algorithm for percentage of carbon calculation inside the furnace combined with a precise PID control, provides a safe and compact control solution even for critical applications.

Single / Dual loop PID controller
Thanks to the third analog input, in addition to the temperature and mV signals required for zirconia probe management, the 1650CC controller is able to control both the Carbon Potential control loop and the furnace temperature control loop.  

Embedded Zirconia proble cleaning Burnoff sequence
The zirconium oxygen probe is a particularly sensitive sensor and due to its installation inside a furnace with a carbon-rich atmosphere, after several hours of operation, it needs cyclic cleaning sequences to remove material deposition on the measuring element, a problem that can cause an error in the measurement of the carbon percentage or reduce the average life of the probe.
For this purpose, the PID controller automatically manages the timed cleaning sequence, also handling the status of the calculated values, which must remain frozen during the cleaning phase.

Zirconia probe diagnostics
Probe diagnostics, useful to verify and ensure the correct functionality of the measurement sensor. Two typical values are used to evaluate proper probe functionality, the impedance and the mV voltage recovery ramp after a Burnoff purge sequence.
Deviation of these values over time, indicating a probe problem, are monitored and reported as alarms by the new Carbon Controller series.  Likewise, any errors during the cyclic purge phase are reported.  

Connectivity and Remote Service
Modbus RTU master/slave, Modbus TCP slave and Modbus RTU/TCP bridge.
Embedded Webserver interface for fast and easy remote assistance.
