Troquemeter Calibration


Recommended Posts



Not sure what you mean by "what is it calibrated by" but the Astar torquemeter reads in transmissable torque in percent. It measures millivolts converted from engine oil bleed pressure.


So I guess they would calibrate the gauge by using millivolts which would equal the percent of torque required.


One reason the B or BA guage reads 83 or 88 percent as redline, is that 83% is the max torque the transmission can take out of the available 641 hp the engine can put out.


I would guess that most helicopters torquemeter reads a redline as max transmissable power(hp or kw) shown as either percent or oil pressure.


Hope it helps.
