The accurate measurement of torque applied to rotating drives and fastening applications is an important criterion for evaluating production efficiency and quality assurance in manufacturing and assembly. There are many process monitoring applications that require rotary style torque sensor be used to capture and record traceable measurement results.
A rotary torque sensor is a finely tuned instrument designed for testing and monitoring torque applications. Designed for torque evaluation and verification, the rotary torque sensor is a laboratory grade instrument that is commonly used for quality control, R&D and calibration applications. The torque sensor connects to a torque tester or torque meter.
This special class of torque sensors require the ability to rotate but be able to measure the torque applied to a joint. Historically rotary torque sensors provided this feature by using brushes, to contact the shaft measuring torque, in a similar manner to the operation of electric motors.
The typical brush type rotary torque sensor has a few disadvantages. These include:
1. Some additional torque is required to overcome the friction of the brushes.
2. There may be problems associated with “brush bounce” in applications of pulse tools with significant vibration.
3. More maintenance is required, especially in high usage applications, because of brush wear.
4. Additionally, high RPM operation will lessen the force on the brushes due to centrifugal force precluding operation at very high RPM
A torque meter is a finely tuned instrument designed for testing and monitoring torque applications. Designed for torque evaluation and verification, a torque meter is a laboratory grade instrument that is commonly used for quality control, R&D and calibration applications.
The PTT torque meter makes ISO 9001 documentation faster and easier. As an advanced torque controlling, monitoring and documentation solution, the torque analyzer enables operators and engineers to ensure product quality, safety and reliability promptly in a variety of manufacturing environments. The portable torque tester features the EZ-Plug & Play technology, which is an auto-recognition system with Mountz torque sensors. The torque meter is designed for measuring torque, torque calibration, joint testing, auditing or for force and load measurement or verification of load cells.
Torque meters can be used to calibrate or test hand screwdrivers, pneumatics screwdrivers, torque wrenches, electric screwdrivers, pulse tools, cordless screwdrivers, torque multipliers and other torque tools. Using a quality torque meter is key for many companies to ensure that the proper torque is being applied. Testing torque is literally a science and not something that can be left to chance.
The TorqueLab®, LTT-Series, is a torque tester that offers portability, expandability and documentation control. Meeting the demands to test multiple torque ranges for various torque tools used in production, maintenance and calibration labs, the LTT features the EZ-Plug & Play technology, which is an auto-recognition system for Mountz torque sensors. The torque tester is designed for torque calibration, joint testing, auditing or for force and load measurement or verification of load cells.
The EZ-Plug & Play feature of the LTT facilitates and expedites the process of setting up and running tool tests, as well as the transfer, analysis and storage of test data for ISO/SPC documentation purposes. The combined hard-software manufacturing solution offers tool testing, graphing capabilities and a graphical menu for easy navigation.
As an advanced torque controlling, monitoring and documentation solution, LTT enables operators and engineers to ensure product quality, safety and reliability promptly in a variety of manufacturing environments. The LTT torque tester can calibrate hand screwdrivers, pneumatic tools, torque wrenches, and power tools to avoid over tightening problems such as stripped threads and under tightening problems, which can increase liability and risk of recall.
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.
