GRAS Sound & Vibration Announces New 146AE Rugged Microphone Designed to Perform Under Harshest Conditions

October 19 2017, 03:00
World-renowned manufacturer of high quality measurement microphones and related acoustic equipment, GRAS Sound & Vibration introduced a new, extra durable, high-performance measurement microphone. Designed with the automotive industry in mind, because of its ruggedness, the new GRAS 146AE may have appeal to many industries that require a high-performance solution.

This new measurement microphone set is shock-resistant, waterproof, dust- and oil-resistant and able to withstand extreme high or low temperatures – all without compromising measurement quality.

The 146AE was designed specifically for the demands of automotive testing and can perform accurately and durably under the most extreme test conditions time and time again. This minimizes costly retesting and rescheduling, providing efficiency with consistently high quality data.

When designing the 146AE, GRAS focused on ensuring this microphone would perform in real-life conditions such as strong vibrations, being dropped, extreme temperatures and water, oil or dust (IP67 Rated). The 146AE is ideal for engine compartment measurements and transmission, exhaust and brake noise tests. It withstands rain, high humidity and oil mist, and its dust, water and high-speed particle protected with a replaceable grid, that allows users to just change the filter, not the microphone. Also, the diaphragm is repairable at low cost.

It can be used at high temperatures (125°C) - ideal for engine compartment measurements, and transmission, exhaust and brake noise tests. With a PowerOn Indicator, it provides efficient control of any measurement set-up, while online data ensures access to electronic calibration data for any system software

The 146AE provides consistent and precise data on frequency range and dynamic range as with IEC compatible 1/2” measurement microphones, 3.15Hz – 20kHz, 18dB(A) – 138dB, 50mV/Pa, and comes with a 5 year warranty.

According to GRAS product manager, Jan Hansen, the 146AE offers an alternative to traditional automotive testing microphones. “Our customers have been asking for a robust, dependable and precise microphone set that is tailor-made for automotive testing and we have listened. The 146AE is the only automotive microphone that can deliver accurate data, even when measuring under the most extreme conditions.”
