Sensors for commercial vehicles
April 2010
Sensors & Transducers
The combined level and temperature sensor from JUMO is an aid to vehicle diagnostics in modern commercial vehicles, construction and agricultural machinery.
With this level sensor, based on the hot-wire principle, it is possible to determine the level of the gearbox or engine oil in a 150 mm measurement section. Continuous monitoring of the liquid level provides certainty that the engine is not running with too much oil, or that, unobserved, the level has dropped too low.
The level sensor is also available with an additional temperature sensor. The temperature sensor is designed with a Pt1000 shunt resistor conforming to EN 60751, Class B, in a 2-wire circuit. Pt100 and Pt500 sensors, as well as NTC and semiconductor sensors, are also possible.
The hot-wire voltage signal and the temperature sensor resistance signal are sent separately to the vehicle electronics for evaluation.
The level and temperature sensor is designed for continuous operation from -40 to +140°C.

PDS implementation on mines
Sensors & Transducers
Level 9 vehicle intervention for collision avoidance has been mandatory on South African mines since 2022, yet the effective roll-out of proximity detection systems remains slower than expected. This is not due to the technical limitations of integration but to operational readiness on site.
