The Loading Bench by Mountz Inc. is a laboratory grade instrument designed to enable accurate torque wrench calibration with less physical effort. The Loading Bench simulates torque application conditions with minimum effort and enhanced safety for the calibration technician assuring a more accurate calibration. The calibration instrument enables quick and easy torque wrench calibration and presetting, independent of human influence or transducer side and end load factors. The Mountz Inc. Loading Bench is designed to calibrate torque wrenches in accordance with International Standards ISO6789:2007.

The drive system of the Loading Bench assures the load application eliminates potential operator induced test errors. Built for durable use, the Loading Bench reduces the operator effort required to attain and sustain torque during the calibration process. The Loading Bench features a large handle wheel, which operates in clockwise and counterclockwise directions to allow smooth manual loading.

A torque wrench is considered a measuring tool and must be properly calibrated and maintained on a preventative maintenance and calibration schedule. The adjustable design of the Load Bench allows it to accommodate various size torque wrenches that can be tested with the unit. The gearbox design of the Loading Bench allows for high torque to be applied with minimum effort required from the calibration technician.

Small torque tools go out of calibration with use. To maintain consistent accuracy, small torque tools must be checked periodically for wear or defective parts. A small power or hand torque tool is a measuring tool that must be properly calibrated and maintained.

Mountz, Inc., a specialist in the design and manufacture of torque control products, offers the LPX torque sensor for testing small torque tools. The LPX is a low torque sensor designed for calibrating and testing small hand screwdrivers, torque wrenches and power tools. With it’s with low profile design, the calibration instrument can be used for automated applications, by mounting it to a palletized system. This saves time as there is need to remove the driver from the robot or off the automated system for calibration. These versatile torque sensor is used in conjunction with a torque tester. Mountz offers various LPX models covering a torque range from 1 inch-ounce up to 20 inch-pounds.

In the manufacturing and assembly world, tightening, controlling, or measuring torque fasteners is imperative for production efficiency. An inadequately torqued fastener can vibrate or work loose; conversely, if the tension is too high, the fastener can snap or strip its threads. Faced with these problems, manufacturers are realizing that precise torque control can spell the difference between a safe, reliable, and economical product and complete disaster.

Using a quality torque sensor and torque tester has become increasingly important for many companies to ensure that proper torque is being applied. Testing torque is a science and not something that can be left to chance.

Torque measurement is utilized in three areas of assembly. Controlling torque is quintessential for companies to ensure their product’s quality, safety and reliability isn’t compromised.

Prior to Assembly
Torque testing equipment, like electronic torque tester and  torque sensors are used before assembly process for tool setup or conducting tool capability studies. For tool setup, the tool crib will want to set the torque tool according the torque specification required for the application. For tool capability studies, technicians need to ensure that the torque tool can provide the necessary torque and repeatability that’s required for a potential application.

The equipment used for this torque testing would be:
- Tabletop torque testers with built-in transducers
- Torque analyzer that connects with either stationary torque sensors or rotary torque sensors
- Joint simulators like run down adapters

During  Assembly
For air and electric assembly tools once the torque tool is being used in the production area, many manufacturers like to audit the tool and verify the actual torque being applied to the application or if the tool is starting to fall out of specification. The Rotary Torque Sensor is the ideal torque-auditing tool for testing the actual torque being applied on the assembly application. By connecting a rotary torque sensor between an electric or pneumatic tool and assembly application, you can monitor the torque being applied from the tool to fastener or bolt. This type of torque reading is called a dynamic torque reading. The rotary sensor is connected to torque analyzer, which records and stores the data.
