Force Solutions for Testing Machines

In test and measurement, one of the most common application for force sensors is industrial-scale testing machines of all kinds. Force and torque data is used in several ways with these types of applications. They can be used in the design phase to help perfect a product or component as it relates to force input or output. They can also be used as a monitoring device to tell users when a machine or its accessories need to be repaired or replaced.

For machine makers, product engineers and test lab equipment users, Interface supplies precision load cells, torque transducers, data acquisition devices and accessories.

Machine testing is one of our most prominent use cases for measurement sensors. Interface has seen quite a few different applications across industries. We’ve noted a few of our application notes that highlight these use cases by outlining how force measurement solutions are used in various machines.

Proving Theoretical Cutting Forces of Rotary Ultrasonic Machining

Rotary ultrasonic machining is a hybrid process that combines diamond grinding with ultrasonic machining to provide fast, high-quality drilling of many ceramic and glass applications. This new method has been theoretically proven using computer models. Rotary ultrasonic machining generates forces of a very small magnitude. To prove this theory, any load cell used for measurement must be sensitive, while at the same time retaining high structural stiffness within a compact, low-profile envelope. Interface suggest using its 3A120 3-Axis load cell installed in the rotary ultrasonic machine to measure the forces being applied to a sample part. With clear signals and minimal crosstalk, the applied forces are recorded and stored using an the BSC4D Multi-Channel PC Interface Module. The 3-Axis load cell provides excellent data helping uncover the relationship between machine cutting parameters and the forces applied on the component. Using this knowledge, the machining process can be reliably optimized for new materials and operations. Review the complete cutting forces of rotary ultrasonic machine application note.

Friction TestingFriction Testing Machine

A testing laboratory was looking to replace two single axis load cells used in their friction testing machine with one sensor that could measure force on the x, y, and z axis simultaneously. Interface’s 3A60 3-Axis load cell was installed on their existing machine with an Interface BSC4D-USB Multi-Channel PC Interface hooked directly to a PC laptop to monitor and log the data in real time. The testing laboratory was able to simplify their sensor set-up and improve their data collection, creating more value for their end customer. Friction testing is a common use case.  To learn more about this application for a friction testing machine, go here.

Spring Compression Testing Machine

In an upgrade in machinery and testing equipment, a customer sought a solution to test the performance of their springs in their specially designed spring test stand using a new wireless solution. Interface suggests using the WTS-5200XYZ 3-Axis Force Moment Load Cell which has 3 integral WTSAM-1E Wireless Transmitters and installing it into the customer’s spring compression frame. The WTS-5200XYZ 3-Axis Force Moment Load Cell will measure the force compression of the spring. The integral WTS-AM-1E Wireless Strain Bridge Transmitter Modules will transmit and display the information wirelessly to the LCCA Wireless Instrument enclosure. It can also be programmed to trigger an alarm.  You can read about the spring testing machine here.

Weighing and Packaging Machine

A food brand wanted to weigh the amount of their snacks that is automatically dispersed into the bags during the packaging process. In this case, they also want to weigh their potato chips being packaged and ensure the potato chips are at the exact weight needed due to regulatory standards. Interface’s suggested using multiple SPI Platform Scale Load Cells and install them to the potato multi-head weigher and packaging machine. The SPI Platform Scale Load cells were installed inside of the mount that attaches the head weigher to the packaging machine. Force results from the potato chips were read by the load cells and sent to the ISG Isolated DIN Rail Mount Signal Conditioner, where the customer could control the automated production from their command center. With these products, the customer was able to determine the weight of the potato chips being distributed into their bags with highly accurate results. They also were able to control the automated production process with the provided instrumentation. They will use this same weighing method for other snacks that need to be packaged.
