CMT’s responsiveness went beyond technical support though. “They were great when it comes to customer support,” he added. “When working with the engineering staff it was easy to see that they were very knowledgeable about the instruments and with troubleshooting,” said Orekan. In addition to the VNA instrumentation being a difference maker for their technology, Sensatek has also credited CMT for its responsiveness and technical support. These materials are optimized for dielectric and sensor performance up to 1,700 ☌. Sensatek’s technology is the culmination of over 10 years of R&D on advanced ceramic materials that are robust inside harsh environments and feature elevated temperatures and corrosive gases. This allows Sensatek to wirelessly interrogate the temperature, strain, or pressure on these rotating parts at very high speeds (up to over 1,200 MPH). The sensor is passively ringing at a specific frequency which correlates to a particular temperature, strain, pressure, etc. It then pings the antenna to get frequency sweeps. CMT’s 1-Port VNA -often an R140- is connected to a high temperature cable that terminates within the antenna and reads the sensor. As the sensor passes by the stationary antenna at speeds up to 2000 kph, the antenna communicates with the sensor at RF frequencies. Sensatek’s RF temperature sensor is bonded on rotating equipment such as a jet engine turbine blade. Sensatek’s passive RF sensors determine and report the health status of jet turbine engines, land-based gas turbines, wind turbines, and various other high-powered DUTs with the integration of CMT’s Reflectometers. Sensatek Propulsion Technology develops and manufactures wireless, high-temperature gas turbine sensors to measure heat transfer data for customers in several industries including energy, aviation, and aerospace.
