Local Control and Monitoring

 

Local thermostats are typically dedicated to an individual circuit and installed in close proximity to the heat trace application.
These devices mostly measure the pipe temperature by means of a temperature sensor installed on the pipe or heated surface. Depending on the type, these thermostats may have a display showing the actually measured pipe temperature, the setpoint and indicate the presence of eventual alarms.
