The TSI SureFlow™ Model 8682-ST Static Pressure Controller is designed to maintain constant duct static pressure in up to five separate ducts.

The 8682-ST uses a pressure sensor to measure differential pressure. It is easily configured to accept different pressure sensor ranges, making it suitable for nearly any duct.

The 8682-ST independently modulates dampers or variable frequency drives to maintain proper duct static pressure in up to five separate systems. If any static pressure is too high or too low, the 8682-ST activates an audible and visual alarm. Adjustable alarm delays prevent nuisance alarms due to short-duration transient conditions.

The 8682-ST is easy to integrate with building management systems using alarm relays, analog outputs for measured static pressure, or digital communications. The 8682-ST model supports the open MODBUS protocol.
