Description
The DTD-F series of static / reaction torque transducers have end flanges for bolting between machinery where a direct drive is required. Applications including the testing of automotive drives, aircraft actuator and industrial robots.
The DTD-F flange static torque transducer is constructed from Stainless Steel on capacities up to 10kNm while capacities from 20kNm upwards are constructed from Alloy Steel.
Installation and setup is made fast and simpler with its integral, robust connector.
The design of the DTD-F lends itself readily to customisation, allowing us to offer custom flange sizes and fixing configurations, as well as versions with sealing to IP68 for applications where operating conditions are particularly harsh or involve total submersion.
If you need a torque transducer without a flange end, please see our range of alternative static torque transducers.
