Dual circuit control and monitoring unit


Thermon Group Holdings has announced the introduction of the TraceNet TCM2 Dual Circuit Control and Monitoring Unit, which is the latest addition to the company’s range of remotely-operated heating control and monitoring systems. Like the 18-circuit TraceNet TCM18 Control and Monitoring Unit, the TCM2 makes it possible to remotely maintain heat trace circuits that play a critical role in industrial processing facilities.

To help operators better monitor and control the temperatures of pipes, tanks and heated instruments, the unit is designed to operate reliably in harsh environmental conditions. Heat trace is controlled accurately and monitored continuously, enhancing heat trace efficiency and reliability.

The unit can be operated locally, by remote control or networked via wireless or hard-wire to a computer or distributed control system (DCS) in the facility’s control room. The system continuously monitors every set point, including temperature, current, and ground-leakage current. It then reports locally and transmits key data remotely to the control room. For example, should the temperature or electrical current be too low or high, or should high ground leakage current be detected, the unit senses it and reports it. The operator can review each circuit for temperature, ground current, heater current, the frequency at which it is performing, and alarm status.

The unit relies on resistance temperature detector (RTD) sensors to monitor temperature on the designated pipe or equipment. The system then cycles the heat required to maintain the target temperature. If required, the operator can also adjust every circuit set point on the unit or via remote locations.
