Product Specification

    Hazardous area approved, SST Sensings range of intrinsically safe optical liquid level switches are designed and certified for use in demanding applications where direct contact with hydrocarbons, fuels, and flammable or explosive liquids is likely.

    Using infrared technology and the principle of total internal reflection, our liquid level switches detect the presence or absence of most liquids. An almost instantaneous response time is standard, and switch point repeatability is +/- 1 mm.

    SST liquid level switches have an operating temperature range between -30℃ and +80(-22°F+176°F). Stainless steel housing and a choice of sensing tip materials ensure they are extremely robust and resistant to chemical attack.
