New Si124 range improved bandwidth yields big savings for energy-intensive industries
The Si124 range of acoustic cameras now detects air leaks from 2 - 65 kHz - and the small change means big operational improvements for indus- trial applications across sectors. The Teledyne FLIR range of acous- tic imaging cameras, the Si124, Si124-PD and Si124-LD, now offers an improved bandwidth range for detecting compressed air leaks in in- dustrial settings. The change means that the industry-leading range can now detect leaks from anywhere be- tween 2 to 65 kHz and adds crucial functionality to the previous peak bandwidth of 35 kHz.
While it may seem like a minor change, the operational impact of the improvements cannot be overstated: it means marked savings for industrial applications globally, reducing costs and improving reliability.
The improved Si124 range promises easier, more impactful inspections The range of three cutting-edge Si124 models are now equipped to measure virtually all compressed air leaks in manufacturing settings - regardless of how small and seemingly insignificant. This unique range covering 63 kHz is scientifically the optimal sound spectrum range for detecting leaks, which occur on this measurable threshold. Detecting ranges outside of this spectrum actually detracts from long-term functionality as detecting background noise beyond 65 kHz can interfere with baseline readings and negatively impact leak detection. Failure to detect air leaks can cost companies thousands of pounds
in replacement costs for units that are not operating optimally, and can have a knock-on effect on production when parts are replaced and production lines forced into downtime.
Federico De Lucia, Team Lead of Condition Monitoring Specialists (EMEA Solutions) at Teledyne FLIR explains why this seemingly small change cements the Si124 range as operating across the optimum bandwidth for detecting compressed air leaks in industrial applications. “Let’s look at, for example, a
compressed air leak from a small hole of just 1.5 millimetres and on a network of compressed air at seven bars of pressure. Two years ago, with a price of €0.07 per kilowatt hour, that would have cost a company roughly €1500 (£1300) per year, if we assume an average operating time of 6000 hours.
“Now that the energy situation is more challenging, it means that costs may be three, four, even five times higher in some cases, which could be a cost of up to £7500 a year - which is a shocking amount simply for failing to identify a single small hole in a vital production component. This is staggering when you consider the scale of indus- trial manufacturing and the scope for leaks to crop up unnoticed.”

Early and central fire gas detection risk be contained?
Filter systems represent a central point in most industrial systems because the air extracted from the various machines is usually bun- dled and guided through a pipe / exhaust duct after the filter ele- ments. Precise monitoring of fire gases within this pipeline enables fire incidents to be detected at an early stage not only in the filter but in all connected machines and system parts.
When do which fire gases arise?
Combustion (Fire) gases develop before smoke or flames can be recognized. Depending on the bulk material, certain fire gases arise earlier, later or only to a limited extent. In order to cover exactly this point, REMBE relies not only on the measurement of carbon monoxide (CO) but also on hydrogen (H2), hydrocarbons (HC) and nitrogen ox- ides (Nox). In this way, monitoring can be set flexibly and precisely to process and material.
The handling of bulk solids poses many challenges. One of these chal- lenges is the enormous amount of dust that is created by conveying and processing the different products. In order not to unnecessarily strain the process and employees on site and to expose them to risks, these enormous amounts of dust get extracted. This is the first step in the direction of fire and explosion protection, because dust clouds of flammable powders in the right mixture ratio to oxygen always represent a great danger.
Despite accurate dedusting of the machines, there is still a high fire risk with corresponding bulk goods e.g. through glowing embers trans- ported into the process or self-ignition of the product. So how can this
