The T251-109 can be supplied as a drop-in replacement for the flange driven MCRT Torquemeters and the older 6-02T Torquemeters. The T251-109 is also available as a replacement for the MCRT with SensorData’s i200 AC carrier strain gage signal conditioning electronics attached to the T251-109 housing as shown in the photo above. An optional zero velocity speed sensor is available. Interconnecting cable assemblies are available as an option. SensorData will provide in-house calibration of the T251-109 with customer-supplied electronics for a fee. The T251-109 offers performance superior to the MCRT and 6-02T products.
