Product Description
BKC – Metal Bellows Couplings provide the ideal complement to Magtrol’s TM / TMB / TMHS / TS In-Line Torque Transducers and Sensors, when these are to be mounted in a drive train.
The torque transmission element consists of a metal bellows and 2 clamping hubs. The couplings are both torsionally stiff and flexible in order to compensate for axial, angular and radial misalignment when connecting two shaft ends. The high torsional spring rate of the couplings ensures a high torsional
stiffness and angular precision.
Design & Material
Bellows are made of highly flexible high-grade stainless steel, the hub material of aluminum or steel with a single ISO 4762 radial clamping screw per hub.
Features
- Metal bellows couplings for use with Magtrol TM, TMB, TMHS and new TS In-Line Torque Transducers and Sensors
- Easy to mount
- High Torsional Stiffness
- Diameter Range: 8 – 60 mm
- Radial Clamping Screw hub for smooth shaft
- Ideal for the transmission of large torques

[post_content] => Magtrol’s Model 3411 Torque Display is designed for use with all Magtrol TS, TM, TMHS, TMB and TF Torque Transducers. This easy-to-use device powers the transducer and utilizes high speed processing to display torque, speed and mechanical power. It includes a tare function to help offset any slight residuals caused by couplings or suspended loads. The 3411 may also be used with any torque sensors requiring 24 V DC power (500 mA max.) with ± 5 V DC torque output (± 10 V DC max.) and open collector, TTL or CMOS output for the speed signal.

[post_content] => Magtrol’s In-Line Torque Transducers provide extremely accurate torque and speed measurement over a very broad range. Each model has an integrated conditioning electronic module providing a ±5 VDC (±10 VDC) torque output and an open collector speed output. Magtrol Torque Transducers are very reliable, providing high overload protection, excellent long term stability and high noise immunity.
All transducer models employ our unique non-contact differential transformer torque measuring technology. This measuring technology offers many benefits, most notably that no electronic components rotate during operation.
To provide customers with several price/performance options, Magtrol offers three torque transducer models: basic model (TMB Series), high accuracy (TM Series) and high speed with high accuracy (TMHS Series).
Each transducer consists of a hardened stainless steel shaft with smooth, splined or keyway shaft ends, an anodized aluminium housing containing the guide bearings and an electronic measurement conditioner.
The integrated electronic circuit, supplied by single DC voltage, provides torque and speed signals without any additional amplifier. The transducer is a stand-alone measuring chain. Connections are made by means of a 6-pole male connector mounted on the housing. A removable aluminium base (delivered as standard with TM Series and TMHS Series models, and as an option for TMB Series transducers) allows fixed mounting of the transducer.
