Pressure Differential Gauge

When screw anchoring, a torque reading is required to ensure the pile/pier has been screwed in at the correct specification. Project engineers will generally 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.
