Schneider Electric (Barber Colman) 20-693 2-Pipe Thermostat Tygothane Tube Assembly

The Schneider Electric (Barber Colman) 20-693 Thermostat Tygothan Tube Assembly is applied in HVAC systems as a sense and connection feature of temperature control in two-pipe systems. It is made up of a length-covered sensing tube connecting the thermostat temperature bulb and remote measurement points, which sends pressure changes due to temperature changes. It is installed between the thermostat and the place where the temperature is being measured and it offers precision in thermal response without the use of electronic wiring. This tube system assists in coordinated temperature regulation and control feedback in hydronic, chilled water and airflow-based systems.
