Pressure Sensors for Farming and Agriculture

As a specialist in miniaturized pressure measurement technology, DDM Sensors develops and manufactures high-precision, robust pressure sensors designed exactly for the demanding conditions of modern agriculture and farming. Our pressure sensors deliver the reliable measurement data essential for automation, increased efficiency, and resource conservation in agricultural processes.

Precise Pressure Measurement for the Challenges of Modern Agriculture

In smart farming and precision agriculture, exact pressure measurements form the foundation for automated and optimized processes. Pressure sensors from DDM Sensors enable a significant increase in efficiency and resource conservation by providing precise data for controlling hydraulics, pneumatics, or dosing systems. We design our pressure sensors for maximum reliability, even under extreme operational conditions in farming and agriculture.

Requirements for Pressure Sensors in Agricultural Applications

Mechanical Robustness for Mobile Machinery

Our pressure sensors are designed for use in mobile agricultural machinery and are characterized by high shock and vibration resistance, as demonstrated by the PV-22 series. For hydraulic systems, they offer high overpressure strength of up to 400% and a corresponding burst pressure to safely withstand pressure spikes. Even during rapid load changes and pressure pulsations typical of working hydraulics, our sensors guarantee high stability and measurement accuracy.

Resistance to Environmental Factors

For use under harsh field conditions, we offer pressure sensors with protection classes such as IP67 and optionally up to IP69K, ensuring reliable function even during high-pressure machine cleaning. The use of high-quality stainless steels such as 1.4404 and 1.4435 ensures high resistance to dust, mud, UV radiation, and corrosive media like fertilizers or salt spray.

Electrical Stability for On-Board Power Supplies

The electronics of our pressure sensors are designed for direct connection to 12 V and 24 V vehicle electrical systems and operate reliably across a wide supply voltage range of 8 to 32 VDC. Integrated protection against typical electrical system disturbances, such as load dump and voltage spikes, is implemented as standard. High EMC resistance ensures interference-free operation alongside other electronic components in the agricultural machine.

DDM Sensors Product Portfolio for Agriculture

Our portfolio for agricultural technology includes proven pressure sensors as well as tailored custom solutions. The PV-22 series is a robust all-rounder that is highly versatile thanks to a wide choice of electrical and mechanical connections. For highly dynamic hydraulic systems, our PV25 and PX25 series are particularly suitable as they are optimized for fast response times. For confined installation spaces, the miniaturized PV10 series weighing just 20 g with a diameter of 10 mm presents an ideal solution. Furthermore, DDM Sensors develops customer-specific pressure sensors for farming and agriculture to precisely meet your unique requirements.
