BIM–1 non-contacting non-intrusive continuous torque measuring system was originally designed for gas pumping aggregate GTK–10I (General Electric MS–3002 10MW industrial turbine and Demag centrifugal compressor). BIM–1 can be easily customized to measure shaft power of other machinery.

BIM–1 provides valuable real-time and high-resolution historical operational data (torque, rotational speed and shaft power) which is important to accurately assess machinery condition. In comparison with energy balance or other indirect methods, direct torque measurement allows more precise determination of gas turbine efficiency and heat rate.

The system measures torque using strain gage bridges mounted directly on the power shaft together with signal conditioning and digitizing module. No mechanical modification of the shaft is necessary which is unavoidable when installing standard torque couplings.

Power supply and digital output signals are transmitted through an air transformer without any slip rings or other frictional devices. The system is certified for operation in hazardous areas (zone 2).
