In industry and mobile machinery, hydraulic systems play a crucial role in the transmission of high forces. In order to control and monitor these systems efficiently, safely and precisely, reliable pressure measurement is essential. With the pressure sensors offered by DDM Sensors, you will find the ideal solution for your hydraulic applications.
Pressure sensors for recording hydraulic pressure
DDM Sensors offers a specialized range of hydraulic pressure sensors specifically designed to meet the challenges in this field. Our portfolio includes sensors for various measuring principles to meet a wide range of requirements. These include relative pressure sensors, which measure the pressure in relation to the ambient pressure, absolute pressure sensors, which measure the pressure in relation to a perfect vacuum, and differential pressure sensors, which measure the pressure difference between two points.
Relative pressure sensors
Within the product range for pressure sensors for hydraulics, DDM Sensors also offers relative pressure sensors specially tailored to hydraulic requirements.

What distinguishes pressure sensors from DDM Sensors?
When it comes to pressure sensors for hydraulics, the products from DDM Sensors stand out due to their specific advantages, which are particularly important in demanding hydraulic applications.
- Miniaturization: The sensors are designed so that they can be perfectly integrated even in very small installation spaces.
- Compatibility: Thanks to the possibility of application-specific adaptation, the pressure sensors can be seamlessly integrated into existing systems.
- Precise measurement: Even in small measuring ranges. This means that the sensors provide reliable and accurate measured values even in the millibar range.
Basic data of the pressure sensors at a glance
The pressure sensors for hydraulics from DDM Sensors are characterized by a number of features that ensure their adaptability to a wide range of hydraulic applications.
- Measuring ranges: Ranges from 0 to 250 bar, whereby any intermediate ranges can be realized.
- Precision (total error): The accuracy is described by the total error band and amounts to ≤ 1% of the MB, ≤ 0.5% of the MB or ≤ 0.25% of the MB. This includes errors due to the effects of temperature, non-linearity, hysteresis, zero point and end value adjustment tolerance and temperature effects on the zero point and span.
- Output signals: Available analog signals are 0.5 to 4.5 V, 0 to 5 V, 1 to 6 V, 0 to 10 VDC and 4-20 mA. Digital interfaces such as IO-Link and CAN protocols are available on request.
- Process connections (mechanical connections): Standard connections are G1/4″ female thread and G1/4″ male thread to DIN 3852 T11 including gasket. Other options include M10x1, M14x1.5, 7/16 – 20UNF and Rectus 21.
- Electrical connections: These include connectors such as M12, DIN and Mil-C26482 plugs, as well as Lemo FGG 1B (others on request). Permanently connected cables in various lengths are also possible, with cable assembly according to customer requirements.
- Protection class: The sensors comply with protection class IP67.
- Size: Small sizes are available from a diameter of 10 mm.
- Temperature ranges: Various options are available, including for simple applications 0 – 60°C, standard process -20 to 80°C, standard mobile application -40 to 150°C, extended -40°C to 180°C and special -56 to 150°C.
Simple integration and 100% compatible
A decisive advantage of the pressure sensors for hydraulics from DDM Sensors is their simple integration into existing hydraulic systems. Thanks to the possibility of application-specific customization, the sensors are designed to ensure 100% compatibility with your existing systems. This minimizes implementation effort and ensures that the pressure sensors can be seamlessly integrated into your processes.
Which media can be measured with the pressure sensors?
The hydraulic pressure sensors from DDM Sensors are not only designed for classic hydraulic oil, but can also reliably detect a variety of other media. Thanks to their robust design and choice of materials, they are suitable for measuring aggressive media and various gases. The range includes various oils, including hydraulic oil, transmission oil, engine oil and cooling oils, as well as different fuels such as petrol, diesel, kerosene and e-fuels. Special fluids such as brake fluid and certain refrigerants (e.g. CO2, butane) can also be measured precisely. Even media such as hydrogen, air/fuel mixtures or potentially foodstuffs such as soft drinks can be controlled by the sensors. This versatility makes the pressure sensors from DDM Sensors a flexible solution for a wide range of hydraulic and related applications.
Typical areas of application for pressure sensors in hydraulics
The pressure sensors from DDM Sensors are widely used in a variety of hydraulic systems and environments. A rough distinction can be made between mobile and stationary applications.
In mobile hydraulics, the sensors are used for test drives in the automotive industry, for example. Another important area is crane and lifting technology, where they are used to monitor support legs, booms and safety circuits in truck-mounted loader cranes or aerial work platforms, for example.
For stationary applications, the pressure sensors are ideal for use in test benches and test systems. Here they enable simulations and load tests of components as well as the testing of tightness, load capacity and pressure behavior.
This variety of applications underlines the adaptability and robustness of DDM Sensors pressure sensors for the specific requirements of hydraulic systems.
Fast delivery times and high availability
DDM Sensors attaches great importance to consistent availability and predictable delivery times for its pressure sensors. The typical delivery time is 3 to 4 weeks. This time is necessary because the production of a high-quality pressure sensor with long-term stability involves important process steps, such as the thermal ageing process and temperature compensation. In order to guarantee high availability despite these quality assurance steps, DDM Sensors relies on strategic long-term procurement and warehousing.
