Ludwig Schneider is a leading manufacturer of engine glass thermometers known for their high accuracy and durability. Manufactured in Germany, our industrial glass thermometers offer easy installation, clear readability and reliable performance.

The liquid-filled engine glass thermometers feature long service life and low maintenance costs. Used in diesel engines, turbines, power plants, compressors, shipbuilding, refrigeration, heating and chemical industries, our industrial glass thermometers have proven to be economical and flexible. Customers rely on the quality of our engine glass thermometers for demanding industrial applications.

Double function engine glass thermometers are special thermometers which contain an integrated Pt100 sensor in addition to the classic temperature display. This makes it possible to read the temperature directly on the double function engine glass thermometer and at the same time use the values recorded by the Pt100 for external visualization or data processing.

Our double function engine glass thermometers are available with one or two Pt100 sensors. One Pt100 is connected via the 3-wire circuit.

If two Pt100 are used, the connection is made in 2-wire circuit. Upon request, we can supply the double function engine glass thermometer with an optional 4-20 mA interface. This interface reduces interference with longer connection cables and is installed in an additional connection head.

Since 1910, Ludwig Schneider has been a trusted name in precision temperature measurement, proudly manufacturing analog thermometers of exceptional quality in Germany. Our comprehensive product range includes bimetal dial thermometers, known for their reliability, ease of use, and versatility across various industrial applications.

For environments requiring quick and accurate readings, we offer gas-filled dial thermometers with probe and remote sensors. These models feature a rigid stem and can be equipped with long-distance cables up to 40 meters, ensuring fast response and a high degree of accuracy (±1%).

In demanding settings, our waterproof flue gas models function as high temp dial thermometers, built to withstand extreme conditions while offering superb durability and corrosion resistance. Whether standard or custom-made, each dial thermometer can be tailored to your needs – including special dials, markings, and mounting configurations.
