FLIR Si124 LD Plus Acoustic Imaging Camera

Description

FLIR Si124-LD Plus Acoustic Imaging Camera – Industrial Compressed Air Leak Detection System with 124-Microphone Array

The FLIR Si124-LD Plus Acoustic Imaging Camera is a professional industrial acoustic imaging system designed to quickly locate and quantify compressed-air and pressurized gas leaks in demanding industrial environments.

The camera uses 124 low-noise MEMS microphones to capture ultrasonic sound and generate a real-time acoustic image. The acoustic image is overlaid onto the digital camera view, allowing operators to visually pinpoint the location of a leak even in noisy industrial environments. FLIR states that the Si124-LD Plus can help users identify leaks up to 10 times faster than traditional methods.

The system supports automatic distance measurement and filtering and can detect very small leaks. FLIR specifies a typical detection capability of more than 0.011 L/min at 3 bar from 3 m and more than 0.024 L/min at 3 bar from 10 m, with an absolute minimum detection level of 0.004 L/min at 1.2 bar from less than 1 m in quiet conditions.

Key Features

124-Microphone Acoustic Array
The Si124-LD Plus incorporates 124 low-noise MEMS microphones to capture ultrasonic sound and create an acoustic image in real time.

This microphone array allows operators to locate the source of compressed-air leaks visually instead of relying solely on audible ultrasonic signals.

Compressed-Air Leak Detection
The Si124-LD Plus is specifically designed for finding and quantifying leaks in compressed-air systems.

Typical inspection targets include:
Compressed-air lines
Pneumatic equipment
Fittings
Valves
Couplings
Hoses
Connectors
Pressure systems
Manufacturing equipment

Acoustic Image Overlay
The acoustic image is displayed over the digital camera image in real time, making it easier to identify the exact physical location of a sound source.

Automatic Distance Measurement
The system supports measurements from approximately 0.3 m to 130 m, helping operators estimate the location and severity of detected leaks from a practical inspection distance.

Automatic Filtering
The Si124-LD Plus includes automatic filtering designed to help isolate relevant acoustic signals from background industrial noise.

Leak Quantification
The system provides leak-rate information that can help maintenance teams estimate the amount of compressed air being lost and prioritize repairs.

This can support energy-efficiency programs by identifying leaks that contribute to unnecessary compressor load and operating costs.

FLIR Software Support
The Si124-LD Plus supports the FLIR Acoustic Camera Viewer for web-based acoustic analysis and reporting. Acoustic images can also be imported into FLIR Thermal Studio Suite for offline editing, analysis and advanced reporting.
