Product Overview
The Hirschmann pSENS DAVS 300/1511-01 is a compact industrial pressure sensor designed for continuous pressure measurement in heavy machinery and mobile equipment. With a measuring range of 0 to 300 bar and a 10–35 V DC supply, it is commonly used in hydraulic circuits, crane load moment systems, boom pressure monitoring, and safety-related control applications.
This model carries part number 8123AQ091237 and is built with a stainless steel housing for durability in industrial environments. The M12 electrical interface and threaded process connection make it suitable for service replacement and system integration in demanding off-highway machinery.
Key Design and Performance Features
300 bar Measuring Range: Designed for medium-to-high pressure hydraulic circuits found in lifting equipment and construction machinery.
Wide Voltage Supply: Operates from 10 to 35 V DC, supporting typical 12 V and 24 V mobile machine electrical systems.
Analog Voltage Output: Provides a proportional voltage signal that can be processed by crane controllers, load indicators, PLCs, and other electronic control units.
Stainless Steel Construction: All-welded or sealed stainless steel housing improves resistance to corrosion, hydraulic oil, moisture, and vibration.
IP67 Protection: Suitable for outdoor and heavy industrial use where dust, water spray, and temporary wetting may occur.
Wide Temperature Capability: Rated for operation from -40°C to +70°C, supporting use in both cold and warm climate zones.
Compact and Lightweight: Small cylindrical form factor allows installation in space-constrained hydraulic manifolds and control blocks.
Reliable Field Performance: Engineered for long-term stability under vibration, mechanical shock, and continuous hydraulic operation.
Applications in Construction and Lifting Equipment
This pressure transducer is typically applied wherever hydraulic pressure needs to be measured, monitored, or fed into a safety control system:
Mobile truck cranes and all-terrain cranes
Crawler cranes and lattice boom cranes
Load moment indicator (LMI) and safe load indicator (SLI) systems
Boom raise/lower cylinder pressure monitoring
Main hydraulic pump and circuit pressure sensing
Outrigger and stabilizer leg pressure detection
Construction machinery, telehandlers, and heavy industrial vehicles
Installation and Compatibility Notes
The sensor connects to the hydraulic circuit via a threaded process port and seals with an integrated washer. The electrical output is transmitted through an M12 male connector, which is widely used in industrial machinery and crane electronics. During installation, the hydraulic system should be depressurized, and the correct thread size, sealing condition, and output configuration should be confirmed before start-up.
This unit is compatible with a wide range of crane and construction machine brands, including XCMG, Sany, Zoomlion, Liebherr, Manitowoc, Terex, and Grove. It is often used as a direct replacement sensor in hydraulic pressure monitoring and load moment limitation systems.
