PU502E is a compact pressure transmitter designed for accurate pressure monitoring in mobile machinery and hydraulic systems. It provides a 0 to 100 bar measuring range for medium-pressure applications. The robust stainless-steel construction provides high resistance to mechanical shock and vibration. Its compact housing allows installation in areas where mounting space is restricted. The transmitter provides stable, repeatable pressure measurement for continuous machine operation.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
PU502E is designed to reliably detect system pressure in mobile machines and associated hydraulic circuits. The transmitter uses a G 1/4 external threaded process connection for secure pressure-port installation. Its analogue output provides a proportional electrical signal to compatible control equipment. The compact cylindrical housing supports installation close to hydraulic pressure sources. High measurement repeatability and low characteristic deviation contribute to dependable system monitoring.
PU502E measures relative pressure from 0 to 100 bar, equivalent to 0 to 1450 psi. Its analogue output responds rapidly to changing pressure conditions with a 2 ms step response time. Repeatability is specified at less than ±0.05% of span under defined conditions. Linearity deviation is below ±0.25% BFSL and hysteresis deviation is below ±0.2%. These characteristics make the transmitter suitable for pressure control, diagnostics and machine protection.
PU502E uses a cylindrical stainless-steel housing with dimensions of approximately 19 mm diameter and 66 mm length. The pressure-contact components are manufactured from stainless steel 17-4 PH for demanding applications. The transmitter is designed for a minimum of 60 million pressure cycles at 1.2 times nominal pressure. Its shock resistance is specified at 500 g and vibration resistance at 20 g. IP67 and IP69K protection supports reliable use in harsh mobile-machine environments.
