The measurement of torque is common practice in all types of aerospace engines, and is used to improve safety, pilot control and engine reliability. Transense SAW sensor technology offer advantages in these applications due to its accuracy over other technologies. Our sensor system is robust, and compact in size and weight. Its ability to measure or compensate for temperature fluctuations, and immunity from background electromagnetic interference, make it the ideal choice.

Based on our sensor performance in harsh mechanical and environmental conditions GE selected Transense SAW sensor technology under licence for the U.S. Army’s Improved Turbine Engine Program (ITEP), which is to replace the GE T700 series engines on all Army Black Hawk and Apache helicopters. The new engine will be used on one or more of the Army’s Future Vertical Lift platforms offering; 50% more power, 25% more fuel efficiency, higher levels of performance at 6,000ft and 35°C (95°F) and 6,000 new engines for the existing helicopter fleet.

Transense SAW sensors are also well suited to the growing UAM Market. See SAW in Electric Motors for vehicles and eVTOL for more information.

Electric Motors and Drives (EMD)

Electric Motors and Drives (EMD)

As the market for electrified vehicle powertrain develops rapidly, the quest to deliver improved efficiency and performance in electric drive systems is paramount. Maximising vehicle range for a given battery capacity is a key target of every powertrain development programme, alongside maintaining and improving the safety integrity of the powertrain system.

The present state of the art is to use advanced torque estimation techniques based on electrical current and rotational speed measurements. Accurate torque measurement is desirable but has not been possible using competing torque measurement systems. Using Transense SAW sensors eliminates the need for estimation and gives reliable torque and temperature measurement from the motor rotor that can be used to improve both motor efficiency and safety, and is suitable for the growing EV motor market. See SAW in Electric Motors for vehicles and eVTOL for more information.

EMD also has links into the other sectors with increasing electrification in aerospace and industrial machinery.

Industrial Machinery

Industrial Machinery

Industrial Machinery provides the backbone of many sectors, from mining and construction to agriculture, materials handling and logistics where Transense SAW sensors can be used.

Transense SAW sensors (both robust and reliable) offer solutions to the problems Agricultural vehicles face where the use of SAW sensing of torque and/or temperature in real time, wirelessly can improve accuracy, efficiency and power distribution. This can also contribute to the ability to operate such machines remotely or on a fully autonomous basis and reduce unnecessary breakdowns and costly down-time.

Transense SAW sensor technology can provide an improved way to measure torque, rotation and temperature in robotic systems, virtually eliminating flex and creating high performing and more repeatable robots with more compact joints than has been possible previously. See SAW in Electric Motors for vehicles and eVTOL for more information.

Performance Automotive

Performance Automotive

Transense have successfully designed its torque SAW sensor technology for Electric Power-Assisted Steering (EPAS) in specialised vehicles and with partners McLaren for Motorsport torque-sensing products. For several years Transense SAW Technology has been used in premium motor sport driveline applications to measure delivered torque in race vehicle drivetrains for monitoring and regulatory compliance purposes. In September 2021, the Company agreed as Joint Collaborative Agreement (JCA) with McLaren Applied Ltd to further develop non-contact torque products for this sector.

The performance motorsport market offers a real and active proving ground for new automotive technology which may subsequently be adopted in mainstream vehicles. There is strong overlap with EMD as high volume performance vehicles are increasingly being developed using electric drivetrain. See SAW in Electric Motors for vehicles and eVTOL
