Digital Instrumentation 101

Digital instrumentation used for test and measurement provides faster data input and output, and more robust analytics. Interface offers several types of digital instrumentation devices that transform load cell and strain bridge input into digital data output in numerous protocols and bus formats.

Instrumentation that utilizes analog output has long been the standard in the industry. As new requirements for use cases and applications grow, test and measurement engineers and professionals find digital instrumentation advantageous because of the lower cost, easy integration and scalability. They also like the advantage of daisy-chaining multiple sensors together on a single cable run.

Advancements in sensor technologies coincide with growing demands to gather more testing data. This is seen through the use of multi-axis sensors, along with requirements for multi-channel instrumentation that can integrate into existing systems already designed with specific digital connections and protocols, as highlighted in using Interfaces BX8 with our 6-Axis sensors. Change is also coming with a strong desire to utilize instrumentation that can easily work within cable free environments or in remote locations.

In addition to improving speed of data output, digital instrumentation offers an abundance of benefits. This is primarily due to the digital signal, as they are less susceptible to noise and are more secure. Digital instrumentation typically has built in error detection. Digital signals are best for transmitting signals across longer distances or when you need to allow for simultaneous multi-directional transmissions. Many people like the ease of integration, both into existing networks as well as with other testing devices.

We provided a brief overview of our custom solutions offerings and process a past blog. Today’s post provides an update on what’s new in custom solutions:

New Custom Solutions Offerings

Among the most significant changes to custom solutions is our growing engineered to order offerings for OEM customers. To best serve these customers and testing engineers with premium and affordable force measurement solutions for use in components or products, Interface now offers engineered to order capabilities for the masses. Engineered to order means Interface can deliver force and torque measurement solutions from our massive catalog that are modified to meet the features, specifications, and cost that our customers require, while still retaining the premium accuracy, quality and reliability Interface is known for across every industry we serve.

The possibilities are unlimited with the amount of products Interface in our catalog, including the possibilities of using new designs.

Every year we engage in a host of unique custom solutions projects with our customers. We would like to share of a few of our favorites with you.

Airplane Maintenance – Wireless Customization

When an airplane comes into the shop, engineers often must jack it up to perform maintenance. When you lift a plane, there is always a risk because you can’t put too much stress on the wings and fuselage. To ensure that the maintenance team members weren’t stressing the plane beyond its limits, Interface developed a solution to measure the lifting force of each individual jack used to lift the plane. The solution included a number of Interface Model 1200 Series Load Cell that would transmit the forces applied back to a base station. However, the customization came in the way data was transmitted to the base station. Typically, wires are used for transmission, but in this case, there were 21 load cells used on the lifting equipment. To avoid having 21 wires get in the way, Interface added custom capabilities to the 1200 series to allow it to communicate with the base station wirelessly.

Crane Application – Custom Programming

Lifting heavy objects can be a dangerous job for onsite workers, not to mention, pushing a large industrial crane too far can result in expensive damages and downtime. Therefore, when an Interface’s industrial customer needed to intelligently monitor a crane in the process of lifting, we helped create a custom program to do so. The custom application included a model 1280 and force measurement activated program. Whenever the crane was nearing a weight that was unsafe, an alert was triggered based on the force measurement reading that could either sound an alarm or shut the system down. This created an automated safety system using force data.

Additional Custom Solution Applications and Use Cases are available here. 

Custom solutions are key to Interface’s broad offerings that we provide when off-the-shelf solutions don’t provide exactly what is required.
