And so is the list of reasons why you need to measure torque quickly and accurately. It's critical to controlling industrial assembly processes, product testing, research and development, maintaining quality standards, and a variety of tightening requirements.

So, as a working engineer, you're likely to find yourself measuring torque for anything from the cap on a tube of toothpaste to the mechanical components of computer drives. Or...let's see...the force exerted by the coils of a 20-foot python wrapped around the body of an engineer...

Whatever your torque measurement need, Honeywell Sensotec has a sensor that will help you decide if it's too tight—before it's too late! More

Four bonded strain gages on a specially machined portion of these transducers measure even the slightest torque motion. Both the QWFK-8M and the slightly smaller QWLC-8M are calibrated for clockwise and counterclockwise torque ranging from 25 in. oz. to 300 in.-lb. With their modular stainless steel construction and no moving parts, these little workhorses are ideal for use in harsh industrial conditions. More

This U.S.-made industry workhorse has been measuring torque in all sorts of applications for nearly 50 years. Tiny screws, gears, anything with a critical torque tolerance, can be verified with this simple-to-use device. The Torque Watch mounts directly to the device being measured with, at the most, two simple tools (a keyed chuck and a square socket driver) and measures either clockwise or counterclockwise torque. Rotating the gage gives a direct reading on a clearly visible dial.

Remembering When. Making the Torque Watch even easier to use is its "memory needle," which moves to the point of highest force and stays there so that you don't have to drop everything to write down the measurement. You can also set the needle yourself before applying force to test whether your equipment is out of spec or varying from a historical value.

Thirty-Three Models' Worth of Flexibility. To ensure adaptability to a variety of industrial needs, the Torque Watch comes in three series comprising 33 models that measure torque at low range (0.003–0.60 oz./in.), mid range (0.05–40.0 oz./in.) and high range (15.0–200.0 oz./in.). Other available references are metric (0.06–0.6 to 15–100 g/cm) and System Internationale (0.2–2 to 0.1–0.7 N/mm). All models are equipped with over-torque protection and can be returned to us for servicing and recalibration in our NIST-traceable system.

What Do You Do With a Torque Watch? Torque Watch is all about adaptability. It's widely used in jet engine testing, but it works just as well with small timer motors and gear drives. In the good old days, Torque Watch made sure that the flashcubes for Kodak's then-revolutionary Instamatic camera required just the right amount of twist.

But Torque Watch is not just about motors. It's helped measure the proper torque on toothpaste caps and the rotary force needed to twirl a lipstick smoothly out of its tube.
