Bluetest adds option to integrate R&S CMX500 5G radio communication tester into its RTS reverberation test systems

Users of Bluetest reverberation test systems (RTS) can now enjoy the benefits of the R&S CMX500 5G NR radio communication tester from Rohde & Schwarz for 5G FR1 MIMO over-the-air (OTA) measurements.

With the R&S CMX500 integrated in the Bluetest Flow control software, the solution provides a stable and reliable environment for measuring throughput as well as receiver sensitivity and output power on multicarrier devices with up to 4x4 MIMO.

The reverberation chambers from Bluetest in combination with the R&S CMX500 now enable developers and manufacturers of 5G components and devices to perform MIMO stress testing under realistic conditions with high data rates.

Power transmission torque measurement: NCTE’s inline shaft mounted torque sensors are available from Ixthus

The German manufacturer NCTE develops and manufactures in-line shaft sensors that measure torque and other forces such as shear and bending moment. 

Available with full support in the UK from Ixthus Instrumentation, these directly mounted sensors are especially practical for dynamic, high precision load measurement of power transmission and power take-off (PTO) shafts where real-time data acquisition provides not just the safe operation of connected machinery but also the ability to optimise efficiency and operation for the entire drive’s function.

NCTE sensors are designed to form part of the drive chain as a ‘plug and play’ component complete with integrated signal conditioning and with no other components required. With several sized model options available torque measurement, from a zero reference, can range from 1 to 10,000 Nm.

Real-world torque measurements enable electric car competition to go virtual

Student engineers are using a newly launched torque sensor for predicting the energy efficiency of a competition-grade electric car.

Young technologists from the University of Sheffield alleviated their disappointment at the Covid-cancellation of Shell Eco Challenge Rally by instead developing a computer simulation tool for predicting electric cars’ energy efficiency. 

The university has a long association with the Shell Eco Challenge, in which student teams from around Europe compete to see whose car electric will cover the greatest distance on a single charge. So, when Covid shut down the event, rather than abandon their efforts Team Sheffield shifted their focus and set about a related project.

Pressure, vacuum and differential pressure switches from Variohm EuroSensor

Developed for harsh aerospace environments, each of VEP’s five product series’ cover pressure, vacuum or differential switching with wide flexibility in mechanical and electrical options.

For example, VEP’s 490 series has field adjustable pressure ranges from 3.0 to 3,000 PSI in a lightweight gold-plated aluminium housing with a dual-spring and stainless-steel piston design that maximises accuracy and stability as well as allow high proof pressure to 4500 PSI. Designed to meet FAA’s 15-minute flame test requirement, the 490 has an altitude range from -1000 to 50,000 feet and, like all other product series available, offers SPDT switching at 5 Amps-resistive from a 30 V DC supply.
