String Pot Sensor
A String Pot or Draw Wire sensor are sensors used for vertical displacement material compression and creep monitoring.
 
The sensors are typically packaged in a NEMA rated enclosure with an extended wire attached to it allowing it to span from floor to floor in a building. Depending on the expected travel, different models are available. The compact size, wide variety of travel ranges and favorable price as compared to LVDTs make this sensor attractive in a variety of different applications. See ASTM publication Volume 41, Issue 4 (July 2013) titled Monitoring of Vertical Movement in Four-Story Wood-Frame Building in Coastal British Columbia for detailed information on how String Pots can be used to monitor vertical displacement and compression of buildings.
