A TorqSense torque sensor is helping Powertrain Technologies reduce engine emissions and improve economy as part of a project to develop an intelligent lubrication system. The engine being tested was a current production Diesel and the test bed was configured for motored friction tests with a 6,000rpm 32kW electric motor driving the engine. The engine lubrication system was re-designed with a bank of five computer controlled oil pumps, each capable of supplying individual parts of the engine with oil under conditions unique to that part of the engine and sensitive to the engine operating conditions. The torque sensor is critical to the project since the object is to measure the effect on friction of a range of different oil supply strategies and oil types. Thus the changes in friction are represented by a change in the motored drive torque of the engine.
In the world of pharmaceuticals product integrity is paramount and packaging has a key role to play. CapCoder of Oxford use TorqSense transducers at the core of its specialist bottle sealing machines. These capping machines not only tighten bottle caps within precisely defined tolerance but also log every detail of every bottle that is capped. A batch size is typically 10,000 bottles, which are capped at a rate of one per second. Every cap has to be done up to the same torque, and proof of this performance is required. The machine had to run the torque up to 10kgf.cm within tolerances of 10% recording the actual value achieved. This secures the cap at a level of tightness that will ensure security and sterility, yet can be opened relatively easily by an adult. The logged values are saved using TorqView software to provide a permanent record for traceability.
The new wireless LoadSense load cell provides all the information needed to optimize efficiency and increase profitability of a wide range of industrial operations. The new development allows weighing processes to be fully integrated with handling operations. All live data is captured in real time and can be transferred to a database, stored, totalized and analyzed. The load sensor can be integrated with a crane hook, fork lift or other handling device. It has an on-board single-chip computer for recording, analyzing and archiving readings, and wireless communications (operating on a harmonized global 2.4 GHz waveband) that can transfer data in real time to a host computer. Internal batteries make LoadSense’s operation completely autonomous. As such it can be deployed with minimal disruption to operations, and will automatically begin transmitting data. No special training is required to install or operate the unit. Multichannel operation is standard.
