A base model "5115" is an inline rotating torque meter with non-contact Rotary Transformer Signal Transmission.  It has a Floating Aluminum Housing and Double Male/ Double Key Shaft and is in the 2,000 to 10,000 in.-lbs. capacity range.

"F52" designates a full scale capacity of 5000 in. lbs., with an overload capability of 500% of full scale or 25,000 in. lbs. and a full scale output of 2mV/V.

"2A4" specifies an excitation frequency of 3 kHz, Non-Repeatability: <0.02% of rated output, Non-linearity: <0.05% of rated output, Hysteresis: <0.05% of rated output, Zero balance: 2% of rated output, Bridge resistance: 350 ohms nominal, Useable temperature range: -65 to+170 F, Temperature effect on output: 0.001% / F  of rated output Temperature effect on zero balance 0.001% / F of rated output, Excitation voltage 3 to 10 AC  RMS, Bridge current at 5 VAC 50  ma, and Insulation resistance: >5000 mega ohms bridge to case.
