vehicle comfort and safety – Miniaturized and fast: Differential pressure sensors measure pressure pulses in vehicles
Vehicles product quality is perceived via various human senses: In addition to smell, optics and haptics, acoustics also influence the perceived driving comfort and the sense of well-being when driving.
Among others one important factor, is the pressure impulse that occurs when the doors of a vehicle are slammed. If this peak pressure is too high, it can be very unpleasant for the ears. In addition, too much pressure inside the vehicle can also prevent closing and the doors completely.
sustainable energy supply – Hydrogen-compatible DDM pressure sensor for fuel cells
Hydrogen has become an indispensable part of the future energy mix. Our team supported a large research laboratory in the development of new and more efficient fuel cells. In the context of a long-term test carried out over 4 months of a low-temperature polymer electrolyte membrane fuel cell stack, DDM pressure sensors were used in the anode path of the stack. The media compositions at the pressure sensors corresponded to realistic compositions. The involved medium consisted of different concentrations of hydrogen, nitrogen, water vapor and liquid water. The sensing element and pressure connections of our hydrogen-compatible pressure sensors are made from 316l stainless steel. The construction is fully welded and 100% helium leak tested. Each sensor is supplied against a manufacturer declaration for hydrogen use.
efficient development work – Cost reduction and permanent availability with the DDM flow calibration rig
The calibration of flow meters is a complex process. Generally speaking, this work is carried out by calibration laboratories having the appropriate technical equipment. In addition to the calibration costs, there is the downtime which may be significant for the customer.
complex missions – Maximum integration capability: DDM pressure sensors for filling systems
The filling of complex systems requires a sophisticated filling process. A time-optimised process with short cycle times is crucial when it is about economic efficiency. To permit the most rapid filling a number of process steps are required. Their dynamic sequence is determined by the geometry of the unit to be filled and by the fluid properties of the filling medium itself. The typical areas of application are refrigerators, air conditioning systems, heat pumps, systems for braking, cooling, air conditioning, engines, gearboxes, hydraulics or windshield wiper systems. The most important parameter for a short cycle is the process pressure. It is crucial that the pressure sensor is fully integrated within the hydraulic system to respond immediate for any pressure change.
discovery missions – Highly accurate, flexible and stable: pressure measurement in space laboratory.
Various experiments of a biological, chemical or physical nature are carried out at an almost daily basis on the ISS space laboratory. Reliabilty of instrumentation is the most important factor. Therefore some of the experiments were tested on Earth under weightlessness simulated. This is why those instruments are temporary brought into the orbit with small rockets. In this context, for the measurement of various electrical and physical parametres, highly precise and reliable sensors are essential. Therefore the DDM pressure sensor PV 15 series was selected and proven to perform as expected.
sustainable agriculture Dynamic and highly precise: application of fertilizers and pesticides according to the requirements.
To be able to operate agricultural cultivation economically, you have to use fertilizers and pesticides.
An excessively high dosage is costly, damages the soil and groundwater.
Liquid fertilizers and pesticides can be applied in a more targeted manner according to the soil behavier.
DDM flow meters are robust and media-resistant. They measure the flow rate in real time, allowing exact dosing at high driving speed and documentation of the amounts of plant agents applied.
sustainable mobility Miniaturized flow measurement with media exposed temperature probe.
Optimised thermal management systems for electric vehicles contribute to an efficient, economical and comfortable mobility. Smart cooling and heat management increases the range of electric vehicle. As a consequence, it also increases their attractiveness and suitability for everyday use. Flow rate and coolant temperature are required to design the system components. DDM coolant sensors measure the flow rate and medium temperature with high accuracy. They are perfect miniaturized to fit even when space is very limited.
interference-free and sustainable upgrades Digital RF speed sensor (Smart Pickoff) upgrades existing turbine flow meters
In some cases, existing turbine flow meters that are still running well are taken out of service because the associated instrumentation system does not perform with reliable flow readings any more. These faults, for example indicate readings at now flow and the other way round. More serious are flow rate readings with increased uncertainty. Malfunctions are more likely caused by the electronic part of the measurement system rather than by the turbine flow meters itself.
Accurate dosing – small and cost-effective – Flow meters for food and beverage.
Pelton wheel flow meters are small and cost-effective flow meters for liquids and are suitable for batching processes and dispensing applications particularly within the food and beverage, chemical and laboratory sectors.
Perfect thermal management – Differential pressure sensor suitable for road tests provides precise data on complex circuits in cooling systems
Even in modern hybrid or electric vehicles, heat is produced as a waste product, or heat and cold are required to supply the power electronics, the drive, the battery and also the passenger compartment with the optimum temperature in each case.
To coordinate these extensive tasks of the cooling system, an elaborate and complex thermal management system is required.
Safe braking for all drives – Miniature pressure sensor for measuring brake pressure control and consistency
Regardless of whether vehicles are powered by combustion engines, hybrids or electric drives, every vehicle must be braked as reliably and safely as possible. In addition to electrical recuperation, this is done via hydraulic brakes.
