MI Series System Configuration Examples

MI Series System Configuration Examples

* For measurements up to 100 kHz, please consider the CF-9200A/9400A or DS-5000 100 kHz unit. (Discontinued products) The CF-7200, DS-3000, and DS-2000 series 100 kHz units are also compatible.

* MI-1282M10 Low Noise Microphone Compatible Models

  • This software is compatible with the FFT analyzers DS-5000 series, CF-9200A/CF-9400A, and CF-4700A.

  • When used in combination with the FFT analyzer DS-3000 series, CF-9200/CF-9400 (without A), or CF-4700 (without A), sufficient performance may not be achieved depending on the conditions.
    Modifications will be necessary when using these devices in combination. After modifications, some functions may be limited.
    For further details, please contact your nearest sales office.

It is ideal for removing background noise in simple sound source detection and anomaly detection applications.

Sensor amplifier

SR-2210 2-channel sensor amplifier
Sensor amplifier
Features
This is a 2-channel sensor amplifier for inputting sensors from a constant-current drive amplifier into analyzers or recorders such as DATs that do not support constant-current amplifiers. It features two power supply options: battery power and AC adapter (optional). It can be stacked and secured, and supports multi-channel configurations.

sound calibration
Sound calibration No.1 Sound calibration No.2 Sound calibration No.3
Features
This acoustic calibration conforms to JIS C 1515:2020 Class 1 and has a nominal sound pressure level of 94 dB. In addition to feedback control, it incorporates built-in correction functions for static pressure and temperature, resulting in stable sound output. For high-precision measurements using the low-noise microphone MI-1282M10*, the use of this product is recommended. *Acoustic calibration of low-noise microphones requires an acoustic calibration with a nominal sound pressure level of 94 dB.		 Features
This acoustic calibration conforms to JIS C 1515:2020 Class 1 and has a nominal sound pressure level of 114 dB. It generates a stable sound through internal feedback control. Because it generates a high sound pressure level of 114 dB, it is less susceptible to interference from ambient noise in environments such as factories and outdoors, allowing for calibration in the actual measurement environment.		 Features
This acoustic calibration conforms to JIS C 1515:2004 Class 2 and has a nominal sound pressure level of 94 dB. It can also be used for simple operational checks. It employs a dynamic speaker design, resulting in a low price.
