Home > Products > CM 2GF Monitor and Control

The Problem

• Centralized control and monitoring of the heat trace system.
• Real time, automatic monitoring of each heating cable's electrical functions.
• Need to dramatically reduce maintenance costs.
• Need to reduce problem response time.

Solution

Selecting the CM-2GF allows plant personnel to verify actual installed load current values and perform preventative maintenance by monitoring the actual ground leakage value for each heating circuit. Combining the GF option into the CM-2 totally integrates the temperature control capabilities of the CM-2 with the most advanced load and ground leakage current monitoring available in the industry today.
