SENSORS:Kavlico recently introduced a rugged, aerospace-grade differential pressure (DP) sensor for monitoring pressure drop across a turbine engine style inlet air filter, also known as an inlet barrier filter. The DP sensor monitors filter health by detecting increases in pressure across the filter element. The DP sensor incorporates a piezo-resistive sense element and is available in pressure ranges of 0-1, ±1, ±5 and ±10 PSID, with other options available. Other features include an operating temperature range of -40 to 125C with a storage temperature of -55 to 150C, an accuracy of ±1.5 percent of full scale over the operating temperature and an operating voltage of 5 to 15V dc. The lightweight device (<6.5 oz) is rugged by design and has a housing constructed of an anodized aluminum with an MTBF of 300,000 hours at normal operating temperature. The DP sensor typically provides an output of 50 mV at 10V dc excitation.
The landscape of product development is changing. Electronic components and the devices that use them are shrinking, while power and functionality are rising. As a result, heat management is now in the forefront of the design process.
Ahead of their appearance at Design & Manufacturing Minneapolis, we look at some of the engineering behind two robots from the hit show, BattleBots, as well as some tried-and-true fighting tactics engineers should keep in mind when taking their own robots into battle.
