Optical Level Sensor for Liquids - TED

Economical, Compatible with Many Liquids

The economical TED optical level sensor is compatible with many different liquids and the lens is coating-resistant. It operates independently of liquid properties such as: color, viscosity, dielectric constant, density, conductivity, contamination, and temperature. It is also ideal for applications requiring chemical resistance.

Easy to Install, Reliable

The TED is extremely easy to install. Simply thread the body into a container, reservoir, or pipe. It offers exceptional reliability. The self-contained, solid-state design means that there are no moving parts to wear out. No adjustment or calibration is necessary either for the TED.


The TED is available in either polysulfone or PFA, ensuring compatibility with all metal or plastic containers. It offers a maximum pressure of 200 PSIG and a temperature range of -40 degrees Fahrenheit to 230 degrees Fahrenheit. The supply voltage is 5-35 VDC and the supply current is 33 mA, excluding the load.
