Pressure transmitters for mobile hydraulics must deliver stable measured values under temperature changes, vibrations, and continuous mechanical stress. For mobile machinery and vehicle-integrated hydraulic systems, series with suitable pressure ranges and compact installation dimensions are critical. Additionally, media compatibility and electrical integration into the respective control concept determine operational reliability.
Pressure Transmitters Mobile Hydraulics for Demanding Processes
Under varying thermal conditions, the Total Error Band (TEB) is a critical parameter, as it accounts for relevant measurement deviations including temperature effects. DDM Sensors offers temperature-compensated pressure sensors with a TEB of < 0.25% FS for precise pressure measurement across a wide temperature range. The seal-free, laser-welded design with wetted parts made of 316L stainless steel also ensures high media resistance and robustness in demanding hydraulic applications.

Typical Industrial Applications
Pressure transmitters in mobile hydraulics are used in construction machinery such as excavators, wheel loaders, and cranes, as well as in agricultural and forestry machinery like tractors, harvesters, and forest machines. Other typical fields of application include municipal vehicles, lifting equipment, material handling trucks, and special vehicle manufacturing. In these applications, compact designs, mechanical resilience, and reliable signal transmission in harsh environments are essential.
Flexible Installation and Interfaces
Depending on the series, various threads and connection options are available for mechanical integration. The PV22 covers M10x1, M14x1.5, 7/16-20 UNF, G1/4 male, and Rectus 21; the PV15 is designed with M6x1, M8x1, and M10x1 for particularly compact installation situations. Electrically, voltage outputs are available for direct integration into mobile controllers. Upon request, DDM Sensors customizes pressure connections and special form factors for differing installation constraints.
Tailor-Made Custom Solutions
Mobile hydraulic systems differ in installation space, media, connection geometry, and signal processing. DDM Sensors therefore develops custom pressure connections and special builds for test benches, prototypes, and series applications alongside its standard product range. When making a selection, factors such as pressure range, temperature window, mechanical load, media, and the desired electrical interface must be taken into account.

Frequently Asked Questions About Mobile Hydraulics Pressure Transmitters (FAQ)
Which pressure ranges are available for mobile hydraulics?
For the PV22, pressure ranges from 100 mbar to 150 bar as well as 2 bar to 150 bar are available, both with custom intermediate ranges. The PV15 covers ranges from −1 to 2.5 bar to −1 to 150 bar as well as 0 to 2.5 bar to 0 to 150 bar, both with custom intermediate ranges. The specific choice depends on the hydraulic task and the required measurement window.
Which output signals do the pressure transmitters offer?
The PV22 is available with 0 to 5 V or 1 to 6 V, and the PV15 with 0.5 to 4.5 V. This allows the sensors to be directly integrated into mobile controllers and evaluation units. Signal processing requirements in the vehicle or machine architecture should be taken into account when selecting a sensor.
Which materials are used in contact with the medium?
DDM Sensors uses stainless steel 1.4404 and 1.4435 (316L) as standard for wetted components. The construction is seal-free and laser-welded. Custom solutions are available for special media or connection requirements.
Which mobile hydraulic applications are these sensors suitable for?
Typical application fields include construction machinery, agricultural and forestry machines, municipal vehicles, lifting technology, forklift trucks, and special vehicle engineering. Key selection criteria include compact design, robust build, and proper electrical and mechanical integration into the overall system.
