Serving as direct replacements for electro-optical and mechanical float switches, the LL-01 Sentio Series miniature, ultrasonic liquid level switches pair ultrasonic technology with analog circuitry to precisely measure aerated liquids. The 316L stainless steel sensors are immune to the dielectric or optical properties of liquids. Available with either 1/4" NPT or 1/2" NPT threaded fittings, features include no moving parts, pressure measurement up to 250 psig (1,724 Kpa) with pressures up to 500 psig (3,447 Kpa) available as an option, 5 to 30 Vdc input power, and an operating temperature range from -20°F to +176°F (-29°C to +80°C). Repeatability is 2 mm or better and leak current is less than 50 µA. A datasheet is available at http://meas-spec.com/downloads/LL-01.pdf
