Helical pile monitor and data logger
Digga is pleased to announce their latest product, the Torque Hub,. Utilising the same technology as our previously sold Torque Logic, it delivers over 99% accurate torque readings. Data is sent over a robust 2.4 GHz RF FHSS signal to the handheld display / datalogger. The Torque Hub measures not only torque, but also inclination. This torque monitoring and data logging device is intended to replace the Kelly Bar Adaptor or mount directly onto the drive-head output shaft. It is available in 2”, 2-1/2”, 2-5/8”, 3” hex & 100mm square kelly shaft sizes.
New reporting capabilities
Reports are exportable directly from the display, either via email using a smartphone with its’ hotspot enabled or through the onboard USB port connected to a flash drive.
Torque Hubs are available for drive units with 2”, 2-1/2”, 2-5/8”, 3” hex & 100mm square shafts. With torque ratings from 5,000ft-lbs to 70,000ft-lbs.
More than just torque
Digga's Torque Hub provides you with a 99%+ accurate torque measurement alignment indicator and data logging proven solution.
Replaces Kelly Bar adaptor or mounts directly onto the drive shaft. Available in 2”, 2-1/2”, 2-5/8”, 3” hex & 100mm square kelly hub sizes.
