Pulley torque sensor
SENSOR Developments’ universal pulley torque sensor addresses
the need to measure belt or chain torque on pulley systems.
It is capable of accepting various pulley wheels and shaft
diameters and features a highly accurate integrated sensing
element, capable of resolving low torque levels while being
exposed to high radial loads created by belt drive systems.
It can be used to replace a standard pulley system for engines,
generators, fluid pumps or other motor-driven equipment and
continuously monitors real-time torque while in operation.
The sensor can be adapted to a wide range of belt drive
systems and can be installed in a dynamometer test stand or on
vehicle. Various torque capacities and pulley gears can also be
designed to meet the customer’s specific requirements.

SERCO’s on-site machining units are positioned and locked by
means of a column/arm system resting on the outside diameter of
the part to be machined, allowing internal machining.
Machine installation is quick and easy. After a first visual
positioning, using a simple specific device, a parallelism and
concentricity within a 0.01mm precision can be achieved. A
powerful air motor drives the tool rotation (hydraulic motors on
request) and radial automatic feed, with a choice of two speeds.
The Serco range of portable products includes machining
equipment, boring and surfacing machines, surfacing machines,
grinding machines and lapping machines.
