ASC

Acceleration and Rotation Rate Sensors

ASC sensors

Advanced Sensors Calibration (ASC), headquartered in Pfaffenhofen, Germany, is one of the leading global manufacturers of acceleration and rotation rate sensors, and inertial measurement units (IMUs). ASC sensors are used for crash tests in vehicle development, safety and wear monitoring of rail-bound vehicles, stability monitoring of turbines and measurement of fluctuations in container vessels.

ASC sensors are used in many different environments to meet a wide range of tasks, such as monitoring high-speed trains' vibration control at injection-moulding machines. Diverse areas of application often require precisely customised solutions. Therefore, ASC experts cooperate with customers to develop new sensor solutions or customer-specific adjustments of individual parts, including cables, plugs or modified housings to attach sensors.

ASC implements its products in small batches and with short delivery times, which is crucial for use in development departments. ASC products meet a high quality standard that is ensured by production at its Pfaffenhofen site, where only high-quality sensor elements from renowned European and American manufacturers are used.

ASC cooperates with leading players including Alstom, Balfour Beatty Rail, Beijing Environment Institute, Faiveley Transport, Italcertifer, Siemens Transportation Systems, Siemens AG Österreich, Strainstall, Trenitalia, IMC Test & Measurement and TÜV SÜD Rail.

Typical applications of ASC sensors for railways

ASC can provide sensors for rolling stock testing and commissioning applications, such as modal analysis, passenger comfort and ride quality testing, brake and crash testing, and commissioning tests in laboratories.

The sensors can also be used by service providers to monitor bogies, wheelsets, axlebox bearings and gearboxes.

ASC sensors' infrastructure management applications include track condition and ground borne vibration monitoring, as well as determining soil quality.

Gyroscopes to measure rotating rate

ASC also produces Gyroscopes to measure the rate of rotation (turn). ASC gyroscopes are based on MEMS Technology, which means that the sensors are shock resistant and have a steady signal. ASC gyroscopes are offered in both uniaxial and triaxial models; both come with a range of 100°/s, 300°/s and 1,500°/s.

Inertial measurement units

Inertial measurement units (IMUs) are also part of the ASC product range. The ASCs include three acceleration and three rotation rate sensors each, which measure along a total of six axes. The IMUs are used for driving comfort inspection and in rail-bound traffic.

The ASC IMU is based on MEMS gyroscopes and MEMS accelerometers. Due to the MEMS technology, the sensor is highly shock resistant, and provides a stable signal for the accelerometer and the gyroscope. The IMU can be obtained with acceleration range of 2g, 5g and 10g, and gyroscope range of 100°/s and 300°/s.

Worldwide railway industry reach

ASC has catered for many leaders from different industries around the world with its products' high quality and customised solutions.

In 2010 ASC developed tailor-made sensors, which are used at the bogies within the scope of a new monitoring system for Siemens Mobilities' new Velaro-D high-speed trains. For controlling the oscillations of the bogie, the sensors designed by ASC are directly attached to the bogies. The acceleration sensors operate at a low frequency, and are based on MEMS technology.

Repair and calibration service

ASC offers comprehensive services for sensor maintenance, repairs and calibrations for ASC and third-party products. DAkkS awarded the calibration laboratory of ASC the authority to execute calibrations according to DIN EN ISO/IEC 17025:2005 for acceleration.
