Level and temperature probes

for utility vehicles as well as construction
and agricultural machinery

 Temperature range from -40 to +140 °C
 As level or combined level and temperature probes
 Connection line: cross-linked polyester
 Installation position: standing or suspended
 Measuring path of 50 mm or 62 mm

For optimum motor or gear 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 hot­wire principle allows to determine the filling level of gear or motor oil throughout a measuring
path of up to 100 mm. Only the filling level monitoring will ensure that the motor does not oper­ate with excessive or insufficient oil. This will prevent damage to the motor.

The level probe can also be provided with an additional temperature sensor. The level and tem­perature probe is equipped with a Pt1000 temperature sensor as per DIN EN 60751, cl. B in 2­wire circuit. The design 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 housing can be made of stainless steel, steel or
heavy-duty plastics.

The level and temperature probe is designed for a temperature range from -40 to +140 °C in
permanent operation.
