MIC Series – Miniature Couplings
Product Description
MIC Miniature Couplings provide the ideal complement to Magtrol’s TM / TMB / TMHS / TS In-Line Torque Transducers, when they are mounted in a drive train. They can also be used with any Magtrol Hysteresis (HD), Eddy-Current (WB) or Powder Brake (PB) Dynamometer and Hysteresis Brake (HB).
The couplings consist of one (MIC-6) or two (MIC-5) disc packs, two clamping hubs and a spacer. They are both torsionally stiff and flexible in order to compensate for axial and angular misalignment when connecting two shaft ends. The MIC-5 (double-element coupling) also provides compensation for radial misalignment.
On demand, MIC Series Couplings are available in an electrically isolated version, suitable for temperature up to 100 °C (125 °C max. temperature, short term).
Features

WB and PB Dynamometers - High Torsional stiffness
- Low inertia
- Low weight
- High rotational speed
- Electrically Isolated version available (available on request)

c) Radial misalignments refer to double element coupling (MIC-5-xxxx).
d) At maximum bore
e) Value available on request.
f) The standard versions are manufactured with integer values; the standard tolerance is H7. All diameters and tolerances are possible. Please contact our sales department.
g) CAUTION: for small diameters, the torque can be reduced < 40 %. For more information, please contact our sales department.
Applications
In a drive train installation, double-element miniature couplings are the ideal complement, although single-element couplings can be used for low speed applications in a suspended installation of the toque sensor.
The higher the speed of the application, the more care is required in selecting the coupling and assembling (alignment and balancing) the drive train configuration. Your Magtrol sales representative can assist you in choosing the right coupling for your transducer.
Coupling Selection
In order to ensure a sufficient safety margin, Magtrol recommends that couplings be sized according to the maximum torque supported by the torque transducer. It is strongly recommended to protect all rotating machine parts according to Safety Machine Norms for avoiding injuries. For further information, please contact our sales network who will be able to provide you with personal advice.

[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.
