Blue Level Technologies's VHS rod point level sensor is an extension unit that has an AC/DC universal power supply, low density detection capability as lightweight as 3.12 pounds per cubic foot, and all stainless steel wetted part construction. It uses piezoelectric technology to create harmonic vibrations in the absence of material, and is dampened when material is present using sensor relays. It operates under temperatures as high 266 degrees Fahrenheit or 130 degrees Celsius.
