FLIR SI2X-LD Industrial Acoustic Imaging Camera Detector: Worldwide Buyer's Guide [2026]

The FLIR SI2X-LD Industrial Acoustic Imaging Camera Detector, model FLIR SI2X-LD from Teledyne FLIR, is a handheld acoustic imaging tool that converts inaudible ultrasound into a visual overlay, letting maintenance teams locate compressed air leaks, partial discharge, and bearing faults without shutting down production. It is supplied worldwide through industrial distributors such as 3G Electric.

What is a FLIR SI2X-LD acoustic imaging camera?

A FLIR SI2X-LD is an industrial acoustic imaging camera detector that uses an array of ultrasonic microphones to map sound sources onto a visible-light image. Teledyne FLIR designed the Si2X-LD for predictive maintenance and energy-audit work in compressed air, electrical, and rotating-equipment systems.

Unlike a single-point ultrasonic probe, the SI2X-LD shows the leak or discharge location as a colour overlay on the camera display, so a technician can document the fault in seconds. This makes it a core instrument for compressed-air leak surveys, switchgear partial-discharge inspection, and mechanical fault screening.

How does a FLIR SI2X-LD acoustic imaging camera work?

The camera captures ultrasound in the 2 kHz to 100 kHz range, then overlays the strongest source onto the optical image. Teledyne FLIR's onboard analytics estimate leak rate and cost, and classify partial discharge type, so the operator gets a decision-ready reading rather than raw decibels.

Because the camera is sensitive to ultrasound rather than audible noise, it works in loud plant rooms where a traditional ultrasonic probe would be masked. The result is faster surveys and fewer missed leaks in high-noise environments such as compressor rooms and turbine halls.

FLIR SI2X-LD specifications and accessory compatibility

The table below summarises the measurable attributes buyers ask about most. Values reflect the FLIR Si2-series platform and the accessories stocked by 3G Electric.

Note that the Si124 carrying case and VS80 probe are cross-series accessories; confirm fitment with your 3G Electric representative before ordering for an SI2X-LD deployment.

Types and applications in Worldwide industry

Acoustic imaging cameras are deployed across several Worldwide industrial segments. The SI2X-LD is most often specified for compressed-air leak surveys, where a single survey can recover its cost through reduced compressor load.

• Compressed air systems: locate leaks in headers, dryers, and end-use drops; quantify leak cost in USD per year.
• Electrical inspection: detect partial discharge in switchgear, transformers, and busbars before failure.
• Rotating equipment: screen bearings, gearboxes, and pumps for early-stage mechanical faults.
• Steam and gas systems: identify valve pass-through and trap failures in steam and gas distribution.
• Energy audits: document savings for ISO 50001 and internal efficiency programmes.

How to select a FLIR acoustic imaging camera

1. Define the detection task. Leak surveys, partial discharge, or mechanical screening — each favours different frequency weighting and analytics.
2. Check detection distance and field of view. The SI2X-LD reaches up to 200 m, which suits high-bay and outdoor switchyards.
3. Confirm battery and runtime needs. Carry at least one spare Si2-series battery for full-day surveys.
4. Verify accessory fitment. Cases, probes, and chargers are series-specific; cross-check the SKU against your camera family.
5. Plan for export and voltage. Confirm charger input for 50 Hz or 60 Hz mains and request export documentation if shipping outside your region.
6. Budget in USD. Include spares, case, and calibration in the total cost of ownership.

Product selection ladder: FLIR acoustic imaging accessories and cameras

The table below arranges the FLIR items stocked by 3G Electric from entry accessory to core instrument support. Use it to build a complete SI2X-LD kit.

Step up the ladder when your survey scope expands: add the spare battery before multi-site campaigns, add the VS80 probe when you need visual confirmation inside enclosures, and add the carrying case when the camera travels between sites. For buyers standardising on the Si2 platform, the SI2X-LD is the anchor instrument and the accessories above complete the kit.

Why source the FLIR SI2X-LD through 3G Electric

3G Electric supplies industrial equipment, parts, and supplies across 14 departments — from machining and electrical to pumps, controls, and instrumentation — with deep specialist expertise in combustion, pumps, and controls. We stock 14 FLIR-related products and can interpret your demand, source the right configuration, and quote in USD with export documentation for Worldwide delivery.

Our team supports cross-market voltage and frequency variants, incoterms-neutral supply, and technical selection assistance. We are a distributor and supplier, not an authorised dealer, and we are accountable for getting the right answer rather than promising infinite warehouse stock.

According to Teledyne FLIR's Si2-Series product documentation, 2023: "The FLIR Si2-Series acoustic imaging cameras detect and classify compressed air leaks and partial discharge, helping maintenance teams prioritise repairs and reduce energy costs."

Frequently asked questions

What is the FLIR SI2X-LD used for? The FLIR SI2X-LD is used for compressed-air leak detection, partial-discharge inspection in electrical assets, and mechanical fault screening. It converts ultrasound into a visual overlay so technicians can locate and document faults quickly, even in high-noise industrial environments.

How do I select a FLIR acoustic imaging camera? Match the camera to your detection task, required distance, and analytics needs. Confirm battery runtime, accessory fitment, and charger voltage for your region. For Worldwide buyers, verify export documentation and 50 Hz or 60 Hz charger compatibility before ordering.

Where can I buy the FLIR SI2X-LD in Worldwide? 3G Electric supplies the FLIR SI2X-LD and compatible accessories to Worldwide buyers. Contact us for a USD quote, lead time, and export documentation. We stock 14 FLIR-related products and provide technical selection support.

What accessories are compatible with the FLIR SI2X-LD? The Si2-series replacement battery (SKU 822GY1) supports extended runtime. The Si124 soft carrying case (SKU 783RN5) and VS80 camera probe (SKU 797RC9) are cross-series accessories — confirm fitment with 3G Electric before ordering for an SI2X-LD deployment.

Does the FLIR SI2X-LD work on 50 Hz and 60 Hz power? The camera is battery powered, so operation is independent of mains frequency. The charger, however, must match your local mains — confirm 50 Hz or 60 Hz input and plug type when ordering for Worldwide delivery.

What is the difference between the FLIR SI2X-LD and a standard ultrasonic probe? A standard ultrasonic probe gives a single-point reading. The SI2X-LD images the ultrasound source across the field of view, so you see the leak or discharge location on screen and can document it immediately.
