Reaction Torquemeters are available in several styles, but share one common characteristic...these devices do not have rotating components. They are simple, inexpensive transducers...the torque equivalent of a simple load cell.

If you have a static or quasi-static application requiring the measurement of torque, this type of torquemeter will be your most economical choice.

The various styles are:

Hollow-flanged, available in ranges from 60 lbf-in to 100,000 lbf-in.

"Hollow" indicates that there is a thru-hole down the torque axis.

 

Solid-flanged, available in ranges from 1 lbf-in to 750,000 lbf-in.

"Solid" indicates that there is no hole down the torque axis.

 

Solid-shaft, available in ranges from 1 lbf-in to 300,000 lbf-in.

"Solid" indicates that there is no hole down the torque axis.

 

Square Drive, available in ranges from 300K lbf-in to 3M lbf-in.

For very high torque applications.

 

C-Face, available in ranges from 50 lbf-in to 20,000 lbf-in.

The sensor fits between a C-Face motor and load.

 

 

Electrical Interface:

The C-Face series is unusual in that it includes an on-board amplifier. So this model requires external powering (+12VDC), and will return a fully linearized output signal of +/- 10 Volts, proportional to (bi-directional) torque inputs. As an alternative, the Model 703 Conditioner is a convenient and fully-featured instrument that elegantly meets all interface needs for true "out-of-the-box" convenience. 

All other models above are traditional mV/V Strain Gage transducers, requiring an external AC or DC Strain Gage Amplifier. S. Himmelstein & Co. offers Models 701 and 708 for this purpose.

The Model 703, 701 and 708 all appear similar to this photo.They differ only in their interface circuitry.

 

There are many benefits to pairing a Model 703, 701 or 708 instrument with your Reaction Torquemeter. These instruments are highly configurable, and include a local display, filtering, analog & digital outputs, limit checking and so on. Furthermore, when ordered as a torquemeter/cable/instrument package, a system calibration is performed at the factory for an easy "out-of-the-box" setup when you receive the system.
