Controller Integrates Safety Limit, Temperature Controller into a Heater
September 1, 2006
EHG SL10 system includes a compact temperature controller, two thermocouple sensors, a power-switching device and alert lights for at-temperature notification, power and out-of-range (high/low temperature) alerts, all connected to a heater. The process controller and safety limit have three modules: display only, communications only or display and communications. The display module allows for changes to the controller settings (setpoint, alert setting, on/off or PID control function), while the communications module allows for remote monitoring and adjustment of control settings.
