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.
