Pressure sensors, differential pressure sensors and pressure-temperature sensors from American Sensor Technologies are ideal for windmill applications, which are located in remote areas and are subjected to temperature ranging from -50 to 60°C as well as such corrosion factors as salt, mist and fog. The AST 4000 offers high proof and burst ratings with high EMC protection. Offering filter condition monitoring, the AST5400 provides linear and accurate readings. Allowing both pressure and temperature readings, the AST20HA reduces process penetrations in the hydraulic system. Finally, the AST4510 measures the level of an oil reservoir while offering temperature output as an option.
