Madison Company's optical level switches are useful in a variety of environments. Using phototransistor technology, our optical level switches provide a digital output that indicates the presence or absence of liquid. They excel in diverse environments with temperatures of -40°C to 125°C. They are designed with harsh environments (extreme temperature, pressure, vibration, and shock) in mind.

Madison optical level switches use solid-state technology that is micro-processor compatible to produce digital output. Their rugged design, fast response, and various voltage outputs all combine in an affordable, effective level sensing device. Our optical level switches come in a variety of materials that suit them to specific applications. Our polysulfone and brass optical level switches are perfect for non-coating liquids. Our stainless steel optical level switches are made for high and low temperature harsh environments. We also offer high performance optical level switches that excel in high temperature environments.

Their versatility makes them ideal for a range of applications. Contact us today for more information, specifications, or with any questions.
