When screw anchoring, a torque reading is required to ensure the pile/pier has been screwed in at the correct specification. Project engineers will generallly demand that a specific torque amount is reached depending on what the piles or piers are being used for.
Traditionally, torque is calculated by a single sensor located at the hydraulic pump in the excavator. Unfortunately, this is not accurate as pressure is lost as oil travels up the boom through the drive unit and back again along the boom to the excavator. Pressure readings can be out by as much as 15-20% compared to actual working pressure.
Digga's Pressure Differential Gauge offers a more accurate way of measuring the true hydraulic pressure being applied through the hydraulic motor and gearbox of your drive unit. Hover your mouse over the features´ 'plus' symbol on the diagram below to reveal the respective benefits.
