SST’s range of intrinsically safe optical liquid level switches, approved for use in hazardous areas, is specifically engineered and certified to operate reliably in demanding environments. These include applications where direct exposure to hydrocarbons, fuels, and flammable or explosive liquids is common, making them suitable for critical safety requirements.
Leveraging advanced infrared technology combined with the principle of total internal reflection, SST’s liquid level switches precisely detect the presence or absence of a wide variety of liquids. With an exceptionally fast response time, their performance ensures rapid and accurate readings, while their switch point repeatability of ±1 mm guarantees consistency in even the most challenging conditions.
Designed for resilience, SST’s liquid level switches operate within a broad temperature range of -30°C to +80°C (-22°F to +176°F), ensuring reliable functionality across diverse environments. Constructed with durable stainless steel housing and offering a selection of sensing tip materials, these devices are highly resistant to chemical corrosion and mechanical wear, further enhancing their suitability for harsh industrial settings.
