Some like it hot - accelerometers work at up to 150°C

Advanced Sensors Calibration (ASC) has developed new capacitive sensors especially for use at very high temperatures: the uniaxial ASC T-151 and the triaxial ASC T-153.

In addition to their resistance to high temperatures, the products are distinguished by their high level of shock resistance, making them best suited for use in harsh environments. Initial customers from the oil and gas industry as well as in the field of tunnel construction are already using the sensors.
ASC, a leading manufacturer of accelerometers, is expanding its product range with two accelerometers based on MEMS technology (microelectromechanical systems) that work within a temperature range from -25°C to 150°C.

"The sensors can even be used briefly at 165°C without any damage occurring to them. These temperature ranges are unique for MEMS sensors," explains Peter Bay, Managing Director of ASC.
Possible fields where the sensors can be used include MWD (measurement while drilling) for horizontal or vertical drilling, meaning that the measuring unit does not have to be removed during the drilling. In the automobile industry, the new ASC models are predestined for use in components that can become extremely hot such as the exhaust and brakes. In addition, the accelerometers open up new possibilities for tests in climate-testing laboratories.
Diverse models with measuring ranges from 2g to 100g are available for selection for the various applications. The accelerometers withstand shocks up to 5,000g, have amplified signals and low noise, and have a very light yet durable aluminum housing. Customers can have their cables and plugs individually adjusted to their needs by ASC experts.
