Ludwig Schneider – Engine Glass and Dial Thermometer

ENGINE GLASS AND DIAL THERMOMETER

Engine thermometers and dial thermometers are modern, reliable temperature measuring devices and are naturally manufactured in our company in accordance with DIN standards. Thanks to their functional form and extremely robust design they are suitable for nearly all areas of application and offer manifold installation options.

Our engine thermometers and dial thermometers have truly proven their worth in deployments in diesel engines, turbines, power plants and compressors. They are used and valued in various applications in shipbuilding, in cooling and heating technology, the chemical and petrochemical industry, the energy industry as well as in general engineering and apparatus engineering. To meet your accuracy requirements our products are subject to thorough checks after each manufacturing step as well during the final inspection.

Engine glass thermometers are liquid-filled thermometers. They offer particularly easy installation double-functioned with good and reliable readability. Thanks to their wear resistance, our high-quality engine glass thermometers have an extremely high service life and are low in maintenance. If necessary, the individual components can be replaced easily.

DOUBLE-FUNCTION ENGINE GLASS THERMOMETERS WITH ELECTRICAL PROBES

Double-function engine glass thermometers are manufactured as special engine thermometers with additionally integrated Pt100. This allows you to read the current temperature at the engine glass thermometer and to use the temperature measured with the Pt100 for remote visualization or measurement processing.

Our double-function engine glass thermometer is available with one or two Pt100 units. The connection is affected with a 3-wire circuit when using a Pt100. If a thermometer with two Pt100 units is used they are operated in 2-wire circuit.

We would also be happy to optionally deliver the thermometer with an integrated 4 … 20mA interface to reduce interference at a long connection cable. In this case the 4 … 20mA interface is installed with an additional connection head.

DIAL THERMOMETERS

On the other hand, gas-filled precision dial-thermometers react rapidly and have a high and consistent display accuracy of ±1 % of the full-scale value. With rigid shaft and long-distance piping these can supplied up to 40 m.

Exhaust gas dial thermometers are especially robust, water-, dust- and oil-tight and furthermore react rapidly. Their liquid filling stabilizes them against strong vibrations. They are corrosion protected and have a high service life even under hard conditions.

The dials of our dial thermometers are adapted to application-specific requirements The scale division and figures depend on the respective dial size. As part of a special version we gladly realize special inscriptions or coloured markings on the figure We look forward to your inquiry If required, we gladly also provide a works calibration certificate.
