Abstract
A hand-held measuring appliance includes at least a nuclear magnetic resonance sensor, a control apparatus configured to control the measuring appliance, an evaluation apparatus configured to evaluate a measurement signal supplied by the nuclear magnetic resonance sensor, an output apparatus configured to output ascertained information, and an apparatus for energy supply. The measuring appliance is configured to examine at least one of fuel, oil, and hydraulic fluid.
Claims9
A method of examining at least one of fuel, oil, and hydraulic fluid with a measuring appliance including an apparatus for energy supply, the method comprising:
- generating a measurement signal with at least a nuclear magnetic resonance sensor of the measuring appliance;
- controlling the measuring appliance with a control apparatus of the measuring appliance;
- evaluating the measurement signal supplied by the nuclear magnetic resonance sensor with an evaluation apparatus of the measuring appliance;
- outputting ascertained information based on the evaluated measurement signal corresponding to an examination of at least one of the fuel, the oil, and the hydraulic fluid with an output apparatus of the measuring appliance;
- using the measuring appliance in a vehicle and during operation of the vehicle;
- and
- using the ascertained information for open-loop and/or closed-loop control of at least one component of the vehicle.
A measuring appliance for a vehicle, comprising:
- a nuclear magnetic resonance sensor;
- a control apparatus configured to control the measuring appliance;
- an evaluation apparatus configured to evaluate a measurement signal supplied by the nuclear magnetic resonance sensor;
- an output apparatus configured to output ascertained information based on the evaluated measurement signal;
- and
- an apparatus for energy supply,
- wherein at least one of the nuclear magnetic resonance sensor and the evaluation apparatus is configured to examine at least one of fuel, oil, and hydraulic fluid of the vehicle, and
- wherein the ascertained information is used for open-loop and/or closed-loop control of at least one component of the vehicle.
A method for examining at least one of fuel, oil, and hydraulic fluid of a vehicle with a measuring appliance in the vehicle, comprising:
- calibrating a nuclear magnetic resonance sensor of the measuring appliance using a tetramethylsilane sample provided within the appliance;
- measuring at least one spectrum and/or one relaxation time resulting from an excitation of nuclear spins in at least one of the fuel, the oil, and the hydraulic fluid of the vehicle;
- evaluating measurement signals from the nuclear magnetic resonance sensor by comparing the measurement signals with reference data from a reference database;
- outputting the evaluation results, including at least one of ascertained information and a deviation of ascertained information from reference data of a reference database;
- and
- using the ascertained information for open-loop and/or closed-loop control of at least one component of the vehicle.
