Home > Products > CM-1 - Continuous Heater Cable Monitoring System

The Problem

The need to monitor the operation of a heat trace circuit system, often hundreds of feet long with many circuits and often employing a mixed variety of cable. Failure of any one of these circuits can shut down the entire system-and the entire plant with it: a very expensive occurrence. Circuit failure cannot be anticipated and is never detected until it happens. By then, work stoppages are inevitable. Most heat trace systems demand active observation by staff on duty, 24 hours a day, and expensive, hit-or-miss maintenance.

The Solution

The only patented heat trace monitoring system that automatically monitors heater cables 24 hours a day without periodic observation and costly maintenance.

Capabilities

The ability to monitor status on every circuit in the system, across a range of functions: Temperature controller and heater function - is it on or off? Continuity alarm - breaks in electrical continuity? Current alarm - has current fallen below a set point? Voltage alarm - circuit breaker trips due to cable faults? The ability to monitor all cable types in the same unit: Self-regulating Series Constant-wattage

No need for a monitor wire or end-of-circuit lights.

Alarms which react to tolerances that you set on all vital circuit functions, thereby alerting you to an impending failure before it happens.

No need for surveillance staff or costly trial-and-error maintenance looking for failed circuits. Most importantly, no plant downtime.

Maintenance costs can be reduced up to 70%!
