Product details
Introduction to AWA5810D Measurement Amplifier:
AWA5810D type measuring amplifierIt is a specialized measuring instrument developed using digital true effective value detection technology, which can measure the effective values of voltage, sound pressure, or vibration. It has the advantages of large dynamic range, high accuracy, and good stability, and can be widely used in the fields of acoustics, vibration, and voltage measurement. Meets the requirements of GB/T 3785.1-2010/IEC 61672-1:2013 for 1ji sound level meters.
Using digital true significant value detectionliThe digital audio microphone amplifier of the technology includes A, C, and Z frequency weighting characteristics, which comply with the requirements of GB/T 3785.1-2010/IEC 61672-1:2013 standard for level 1 sound level meters.
The measurement frequency range can be extended to 40 kHz or 80 kHz. Through the front panel LEMO 7-pin socket, it can be connected to a microphone preamplifier and a 1/2-inch or 1-inch test capacitor microphone to form a level 1 sound level meter for acoustic measurement. There is also a direct input jack that can be connected to an accelerometer preamplifier or used as a general high-sensitivity audio electronic voltmeter to measure true RMS voltage. It is a widely used laboratory acoustic, vibration, and voltage measuring instrument that can replace imported measuring amplifiers for acoustic metrology.
