Level and temperature probes for utility vehicles as well as construction and agricultural machinery (90.2880)

For optimum engine or transmission operation, several parameters must be continuously monitored and corrected in the event of deviations. The oil level and the oil temperature are two of these parameters.The combined level and temperature probe supports the vehicle diagnosis of modern utility vehicles, construction and agricultural machinery. This level probe operating according to the hot-wire principle allows to determine the filling level of transmission or engine oil throughout a measuring path of up to 100 mm. Only the filling level monitoring will ensure that the engine does not operate with excessive or insufficient oil. This helps prevent damage to the engine. As an option, the level probe can also be provided with an additional temperature output. As standard, a Pt 1000 temperature probe as per DIN EN 60751, class B, in 2-wire circuit is used. Designs with Pt100 or Pt500 temperature sensors as well as NTC and semi-conductors are also possible.The voltage signal transmitted by the hot-wire and the resistance signal from the temperature sensor are separately transmitted to the vehicle electronics for evaluation.Depending on the customer requirements, the case can be of stainless steel, steel or heavy-duty plastic.The level and temperature probe is designed for a temperature range between -40 ... +140 °C in continuous operation.
