PU501E is a compact pressure transmitter designed for reliable pressure measurement in mobile machinery and hydraulic systems. It provides a 0 to 250 bar measuring range for monitoring demanding pressure conditions. The robust stainless-steel housing offers high resistance to shock and vibration during machine operation. Its compact cylindrical construction is suitable for installations where available space is limited. The transmitter is designed for stable and repeatable pressure measurement over long operating periods.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
PU501E is designed to continuously detect system pressure in mobile machines and hydraulic equipment. The transmitter uses a G 1/4 external threaded process connection for secure installation. Its analogue voltage output can be connected to suitable machine controllers and monitoring systems. High repeatability and low linearity error support consistent pressure information. The device is particularly suitable for demanding mobile applications requiring robust pressure sensing.
The transmitter measures relative pressure across a 0 to 250 bar range. Its 0.5 to 4.5 V analogue output provides a proportional signal for electronic control systems. A 2 ms analogue step response allows fast detection of pressure changes. Repeatability is specified below ±0.05% of span under defined temperature conditions. Long-term stability and low hysteresis help maintain dependable pressure measurement during extended operation.
PU501E features a compact cylindrical stainless-steel housing measuring approximately 19 mm in diameter and 66 mm in length. The wetted components use stainless steel 17-4 PH material for pressure-contact durability. The transmitter is designed for more than 60 million pressure cycles at 1.2 times nominal pressure. Shock resistance reaches 500 g and vibration resistance reaches 20 g under specified test conditions. IP67 and IP69K protection supports operation in demanding mobile-machine environments.
