For nitrogen‑pressure monitoring in accumulator systems and hydraulic‑fluid pressure measurement in hydraulic systems, SCHWERLL offers high‑precision pressure sensors, available with digital display and both digital and analog outputs. The pressure sensors supplied by SCHWERLL have been rigorously tested over long service lives in hydraulic and accumulator applications, demonstrating reliable performance. These are well‑established products, featuring sensor interfaces that fully match the standard ports on system valve blocks, while maintaining a compact installation footprint.
Excessive nitrogen temperature within the accumulator system can lead to overpressure, causing thermal damage to component parts. System operation also imposes strict temperature‑control requirements for the hydraulic fluid. Drawing on years of experience in demanding operating conditions, SCHWERLL offers users a range of temperature sensors designed to monitor nitrogen‑related issues in the accumulator system or to measure the hydraulic fluid temperature in the hydraulic circuit.
The UPS ultrasonic sensor is an external switch-type sensor used to measure piston position. It is mounted on the outer wall of an accumulator or hydraulic cylinder using mounting bases, clamps, and other accessories. During operation, the ultrasonic switch continuously emits ultrasonic signals and receives the reflected echoes. When the liquid level is detected, the switch’s output voltage changes, generating a discrete switching signal.
