Screw anchor monitor & data logger
Digga is pleased to announce their latest product, the Torque Hub. Utilising the same technology as our Torque Logic, it delivers over 99% accurate torque readings. Data is sent over a robust 2.4GHz 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 and suits 75mm Square & 100mm Square 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.
Models available
Torque Hubs are available for drive units with 75mm and 100mm square shafts, and torque ratings from 13,000Nm-95,900Nm. - including Digga's PD15-PD25 and SD range of drives.
More than just torque
Digga's Torque Hub provides you with a 99%+ accurate torque measurement alignment indicator and data logging proven solution.
Simple installation
Replaces Kelly Bar adaptor or mounts directly onto the drive shaft. To suit 75mm Square & 100mm Square shaft sizes.
