PU8501 is a compact mobile pressure transmitter designed for hydraulic pressure measurement. It provides a 0–250 bar measuring range for medium- and high-pressure applications. The transmitter uses a 0.5–4.5 V analogue output for machine controllers. Its robust stainless-steel construction supports demanding operating conditions. The compact form factor simplifies integration into mobile equipment.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
PU8501 continuously measures relative pressure up to 250 bar. The 0.5–4.5 V signal provides proportional pressure information. Fast response supports dynamic pressure monitoring in hydraulic circuits. High repeatability helps provide consistent control feedback. The fixed range simplifies system configuration and replacement.
The transmitter uses a compact stainless-steel pressure measuring construction. Its design is suitable for high vibration and shock environments. IP-rated protection supports outdoor mobile-machine applications. Electrical protection helps improve operational reliability. The compact body enables installation close to hydraulic pressure sources.
PU8501 is suitable for construction and agricultural machinery. It can be installed on hydraulic pumps and power units. Pressure feedback can support machine-control and diagnostic functions. It is suitable for off-highway vehicles and mobile hydraulic equipment. The analogue output integrates easily with compatible machine electronics.
